Hi Tony
Thanks for your advice. I will certainly try Amayama next time I need parts for my Camry.
Meanwhile the Camry is going to my friendly local mechanic tomorrow for him to try and sort it out as I have several other cars in my collection that need my attention.

Paul
PS How do you know about the ridiculous markup.

I recently replaced the drive belt tensioner on my 2003 Camry ACV36R as the old one had developed excessive up and movement whilst the engine was running.
After I installed the new tensioner I found it very difficult to replace the drive belt. The drive belt itself was not replaced as it was still in good condition after a recent water pump replacement.
Using a 19mm socket and a long breaker bar I compressed the tensioner as much as reasonable possible without breaking the 19mm lug off the tensioner.
A common issue according to a number of YouTube videos I consulted.
I found a hack on YouTube using a zip tie to hold the belt onto the crankshaft pulley, whilst turning the crankshaft, which worked but the belt was quite tight.
The new (aftermarket) tensioner appeared to be doing its job as the belt and tensioner were now quite smooth with very little up/down movement at the tensioner pulley wheel.
This lasted for about a week when the old up/down vibrations came back. 
At this point I am not sure about the next step. I checked all the accessory pulleys for smooth operation without any noise or binding when fitting the new tensioner so I don't think they could be the source of the problem.
The only other thing that comes to mind is that when installing the new tensioner, I could not compress it as far as the old one making it difficult to replace the drive belt.

Options that come to mind are:
1. Replace the drive belt with a longer one. Currently have 7PK1935 fitted, could go to 7PK1940.
2. Replace the hydraulic tensioner module in the drive belt tensioner with a genuine Toyota one.

Any thoughts on this, Camry lovers?

Been meaning to post this for a while but a recent incident reminded me of the issue.
The built-in car alarm goes off at apparently random places and times.
However after joining the dots it appears that it is caused by strong electromagnetic radiation (EMF).
During a recent trip to Bribie Island the car was parked underneath a disused water tower that now serves as transmission tower for council and mobile phone antennas.
Other know spots where the alarm is guaranteed to go off is at a friend's place behind an Energex substation and two shopping centres with medical imaging services.

The tripping of the alarm does not cause a fault code to be displayed on the Multifunction Display.
The incidents do not appear to be frequency related but pure EMF force triggering the alarm circuit.

My simple solution is to open the bonnet and disable the horn by pulling the electrical connector off it.
Don't forget to reconnect when you leave!
 

Others on this forum may be interested in the outcome of this problem.
After some searching on Google I found a very good YouTube video (2003 Toyota Camry - Replacement of Evaporator Core, Expansion Valve, and Heater Core (A/C Evap Core) - YouTube) from the USA which explains in detail how to remove all the necessary components without taking all of the dashboard out. 
Its all mirror image of course due to them being LHD.
The auto electrical workshop agreed that if I removed all of the necessary components and purchased the TX Valve they would do all the necessary refrigeration work.
Day1 - Spent the best part of the day on my back in the Camry removing glovebox, fan, electrical wiring, A/C Ducting, etc.
Day2 - Back to workshop to have TX Valve fitted (Denso $77.11), they encountered a few problems getting the old one out as the steel bolts were seized.
Day3 - More time on my back re-assembling the fan box and electrical wiring.
Day4 - Back to workshop to have system regassed and checked.

Success, glorious cold air, an absolute necessity in Brisbane at this time of year, December 2023.

Total cost, $480, which is a big saving over the cost of having it all done by an A/C workshop.

My Air Con had been getting less and less efficient over the last few weeks to the point where it was not worth turning on.
Now with the temperature and humidity in Brisbane rising to uncomfortable levels it was time to get the A/C checked out.

The system was found to be low on gas and recharged but the technician found that there was a blockage in the system that pointed to the TX Valve.
Unfortunately, this is located near the evaporator behind the dashboard, so its a dashboard out job (~$700) for a $100 part.

Other cars have this component accessible in the engine bay.
What was Toyota thinking when they designed this system? 

Has anyone on this Forum experienced the same problem?
What was the outcome?

It has been some time since I lasted posted about this repair but what I discovered maybe of use to others.
T&E Tools make a Toyota Timing Belt Tensioner Compressor.
This little tool, see photo, compresses the timing belt tensioner with the belt still on the pulleys.
This saves having to remove the A/C compressor and the tensioner assembly.
The tool can be purchased from Burson Auto Parts for around $35.00

Thanks Tony, I have had a look at both and they contain some useful tips.
The one thing they all complain about is the removal/replacement of the A/C compressor mounting bracket.
Bad design from a maintenance point of view.

Regards

Paul

The problem is that the water pump pulley is under a lot of tension from the timing belt and the timing belt tensioner is not accessible without removing all of the aforementioned parts. I'm sure that mechanical workshops have devised a shortcut way to do this job, potentially saving them many hours of labour.

Hi Tony and Hayden
Thanks for your responses. 
I tend to agree with your sentiments but for non-critical parts, eg interior trim, aftermarket can prove to be OK.
I replaced some interior and one exterior door handle with aftermarket many years ago and they have been fine.
With second-hand parts it pays to be a bit more careful since the part you are replacing could as old as the original and may also have a short life.
I replaced a broken boot release cable with one from a wrecker's yard, but only after having carefully inspected it.

For my window winder I should have gone with genuine.

Regards

Paul

Recently I returned from the shops and the driver's window refused to windup.
Having experienced this problem before I homed in on the window winder motor and found it to be faulty.
I went back to the shop where I had purchased the window regulator and motor 2 years ago and complained about the failure.
They advised that their warranty was only for 12 months and offered to sell me a replacement motor only for $95.

The motor is now installed in the door and working well but it begs the question regarding the reliability of aftermarket spare parts.
Has anyone else on this forum experienced early failures with aftermarket spare parts?

The original Toyota motor lasted 18 years, the replacement Chinese motor 2 years.

Sometimes its worth paying the extra for the genuine Toyota part.

Paul

I am about to replace the water pump and thermostat on the 5VZ engine of my Prado.
Haynes Workshop manual says to remove the A/C compressor and the crankshaft pulley.
Just wondering if anyone on this forum has found a work-around for this job as all the bolts for the water pump are clearly visible after removing the upper timing belt cover.

Regards

Paul

Hi Ron

Expenses break-down is as follows:

All up Grand Total:                   $1,128.03

The Steel, Flat Bar and Hi Tensile Bolts, in case you're wondering,  was used to make a crankshaft pulley holding tool.

Yep. The 5VZ-FE has three seperate belts, hence three seperate tensioners. All of which are the tradional old school threaded bolts in slide plates. Best to spray them with penetration fluid before attempting to loosen the main tensioner bolt as they have a tendency to seize and potentially snap if you're too vigorous in your removal application 😄

I can confirm the "tendency to seize and potentially snap" as this happened on my Prado.

I omitted some detail in the original posting to keep it short. 
The bolts retaining the stone-guards were rusted in and heads rounded off. I could not get the guards off so I took the car to a local garage (this is before I had my own hoist installed). They removed the bolts and offered to install the belts at the same time. I supplied the belts and left it with them.

When I came to pick the car up they explained that the A/C tensioner was that badly seized that it snapped off. The belt was then tensioned the old fashioned way by using a lever.

I used the same method to tension the A/C belts when I recently replaced the faulty alternator belt.
One day I will replace the A/C belt tensioner but it looks to be a major job.

Finally noticed this from your initial post.

Interested to know further details of this repair whether you DIY or sent to mechanical repair shop.

I sent the head to a local engineering workshop specialising in head reconditioning to be machined in case there was any warping.
The threads in the block were repaired by Mobile Threadfix who came to my house to do the job.

See my posting in a separate thread: https://au.toyotaownersclub.com/forums/topic/58786-2003-camry-acv36r-power-steering-pump/

I took the belt back to Repco who replaced it immediately even though it was well outside the warranty period.
They thought it was a manufacturing fault.

I decided to tally up the cost of these repairs as a guide to others who may be contemplating doing these repairs themselves.

Parts and Services: $917.09

Tools:                        $142.18

Consumables:          $68.76

Total:                       $1,128.03

Of course the tools are now part of my tool collection and will be used on other projects. So too will some of the consumables that were not used up on the job.
I had been given estimates of around $2,500 to have this repair done professionally by a mechanical workshop so there were considerable savings by doing it myself.
Plus of course the satisfaction of doing it myself and learning lots on the way.

Finally got around to fitting the new bush into the shift cable linkage under the centre console. See photos below.

The most difficult part was inserting the bush into the linkage eye at the end of the cable. 
I applied white zinc oxide grease to both the bush and the eye then used a small G-clamp to push the bush in.

         Temporary Fix                                                 Shift Cable Eye                                       Bush Installed                                             Cable Re-attached

At the end of the job I gathered all the plastic bits that had somehow fallen off when the RACQ patrolman was getting me mobile again with his temporary fix (a couple of zip ties). See photo below. He did say that plastic get a bit brittle after a number of years. Most of the bits are redundant as the various components have several fixing points but I will have to glue the curved corner of my gear selector quadrant back in, if only for aesthetic purposes.

Paul

Thanks for the link Ashley, I missed that one during my online search, only found USA based sellers.

My micrometer goes from 1" to 2" so its a bit too big for this small bush but I will use my vernier calipers to record the critical dimensions.

Regards

Paul

After some more prodding, the spare parts man at my local Toyota dealer referred me to a local mechanic who had apparently bought up the last of these bushes when Toyota listed them as a spare part. A quick trip to his garage and $50 later I became the owner of the last Camry auto trans cable bush in captivity. See attached photos of the old and new bush.

Someone with a 3D printer could have a sideline business printing these bushes.

The GM bushes, which looked a bit larger than the genuine item, have gone back to Repco for a refund.
Tomorrow's job will be to fit the new bush.

Regards

Paul

Hi Tony

I went to my local Toyota dealer yesterday and they tried to sell me a complete transmission shift cable for $190 as the plastic bush is not available as a separate part.
When I baulked at the price they suggested I try Repco for an aftermarket part.
Repco have Dorman transmission bushing kits but not specifically for the Camry. They suggested I buy the Dorman 14055 kit, which is intended for GM cars, as this seems to fit a lot of other cars as well. I parted with $50 for a kit which consists of 2 small plastic bushes but haven't had the chance to try it out yet.

Paul

Yesterday, after starting my Camry, I could not engage Drive. The shift lever moved loosely from one end of the quadrant to the other without engaging any gear.
I called RACQ Roadside Service and the technician removed all the centre console trims to expose the end of the shift cable.
Apparently a plastic clip that retains the eye of the shift cable onto the shift lever had perished and fallen off.
He made a temporary repair with a couple of cable ties and I was on my way again.

My question is this, can you buy these plastic clips as a replacement part from Toyota or an after market source?

Has anyone else experienced this problem?

Regards

Paul

Hi Mike

Thanks for the tip. I will check it out at Supercheap and see if its suitable for my Camry.

Problem Solved

I checked and cleaned the PCV valve with TB cleaner and ensured it was working correctly before installing it back into the valve cover.

Next I checked the inlet manifold vacuum and found it to be 17 in Hg on a cold start, rising steadily to 22 in Hg as the engine reached operation temperature.
This is in accordance with the data published in the Haynes workshop manual.

Finally it was time to check to IAC (Idle Air Control) valve. Luckily it could be removed from the car without again removing the throttle body.
It was full of black gunk which I removed with lots of TB cleaner and a small brush.
I then removed the electric actuator from the IAC to check and ensure that the valve could move freely on its shaft.

IAC Valve Body and Actuator

After reassembly I installed the IAC valve on the TB in the car and plugged in the electrical connector.

Upon starting the engine the idle revs went to 1000 RPM and then steadily dropped to around 650 RPM. Joy!

Did some extensive test driving and stopping to check idle, but its perfect.

So to sum up, happy camper, after Camry being off the road for 2 months.

Hi astol87

I have tried your Custom Configuration String on my 2003 Camry ACV36R using Torque Pro and 3 different ELM327 adapters but without success.
All I get is a blinking ABS light. Any recent update to your Configuration String?

The adapters were: Tonwon T2 Bluetooth LE 4.0 (which works fine on my 2005 Jaguar), a generic ELM237 BT adapter, and a WiFi ODBII Diagnostic Interface.

Has any other member on this forum been able to get this working?
I would be keen to learn about your experience.

Hi Damian

This quite an old post but I am experiencing a similar problem.

Did you ever find out what the problem was, and a solution?

Regards

Paul
