I like your cardboard box idea too. Very novel approach.

That was an improvisation on the day. I was more considering numbering/marking the bolts and the relevant holes but you need a good permanent marker/paint pen, space etc. If markings get blurred, is that 1 or 7, 3 or 8, 5 or 6, 6 or 9 etc.

Previously, I have carefully placed parts in a tray in an ordered sequence then accidentally given the tray a boot. Good reason why this time when I removed parts, I put them in the cabin. 

I was also thinking at the time if there had been a photo or diagram of the actual part on the water pump box that I could have poked some holes in that box to use for the water pump bolts. I have kept that thought in mind so in future I may print out a photo or diagram then paste onto cardboard to ensure right bolt goes into the right hole.

Just an update. I had the water pump replaced with a genuine Toyota water pump by a local mechanic at a cost of only $495.

Actually, I reused the coolant which was Nulon Pre-mix with a 8 year life. I drained the radiator and that was approximately 5.5 litres. There was still some coolant in the thermostat housing and

Water pump arrived today. Already spent about 2 hours dismantling. Able to access and loosen all bolts so far and no need for cursing, yet. Tight working space and had to jack up the engine just to ge

That would be a very frustrating moment, with plenty of expletives from me lol !!

Great Idea.  A Pictorial template that way you can marry up all the bolts to the correct holes. Another excellent idea. 👌

Thanks for the video Ash. It's content like this which helps prevent others from making stupid mistakes. It demonstrates how important it is to do careful research and preparation. It's a big job, not impossible, can be daunting to the uninitiated that's for sure. If you can follow the correct procedure you can't make any mistakes.

Never knew about the O-ring in the water pump housing though. Did you replace you're one Ash ? He also used Dielectric grease to condition the O-ring. I wonder if that is something the factory use and what type of O-ring, Nitrile or Viton. I'm going to guess Nitrile as the old one was black and the Viton is the upgrade to this. Would this be correct ?

Note how the tensioner pulley bolt is a reverse thread. So if you're going to remove it in the same manner as the water pump pulley or the other idler pulleys, there's going to be a lot of cursing when you can't figure out why it won't budge lol.

I also like that chain strap vice grip tool to lock and hold the pump pulley. Gotta see about getting one of those babies !!

I did not replace the O-ring but I did use some vasoline to condition it. I do not know about what type of O-ring except that it was black. More than likely with my older 2006 Aurion, it is going to be Nitrile.

A chain strap vice grip would be a handy tool. However, I did not need it and I do have a few oil filter strap tools that could have been used.

While there was still tension on the serpentine belt, I was able to loosen the 4 retaining bolts on the pump pulley. Torque on those bolts in not high so did not need the backup plan of using a screwdriver through one of the pulley holes then hold in place against the pump housing. Just another item in the preparation and planning ahead.

Yeah, welcome to the club 🙂 I was $600 out of pocket for this at an independent when it happened, so $750 at Toyota isn't that much of a rip-off. While it's belly up get them to do the VVT oil line, it's a recall item and should be free of charge if your car is still running on the original rubber crap.

That got done back in 2008, aslo has the Cooling oil lines to external oil cooler replaced out of warranty, 2020, still going to strong with 89000 klm, I hardly drive it now.

I'm guessing if the O-ring isn't damaged in any way I would say that it could be reused but if you have new ones on hand It would make sense to just replace it. I have a small o-ring kit with an assortment of sizes and just need to find out if they are compatible.

I don't like reusing things like O-rings if I can help it, always replace, but each to their own of course 🙂

 

When I had my water pump replaced it came with new O-rings. Wasn't making noise but it was weeping coolant so probably didn't have much more to go in it.

I had forgotten that the new water pump [NPW brand] did come with new O-rings and a gasket. I must have been thinking about re-using the existing O-rings if they had not been included.

Just checked the box and the old O-rings, gasket and pump were inside.

Haha, you're right. It's been a long while since purchasing mine you prompted me to dig mine out and take a look for myself.

Yep. Upon checking I can confirm this. I also purchased a Genuine Toyota gasket some time back as it was going cheap so I had this in the box with the NPW contents. I also noticed the cardboard for the NPW gasket has had the sticker carefully razor bladed off. Not sure why, but I'll be using the Toyota Gasket anyway when it's time to replace my pump. 

Refresh my memory. Where does the larger O-ring go ?

Have another look at the other side of your water pump. You will then notice the groove in the round section offset above the water pulley. 

Also at the 5:46 time of the YouTube video that I posted, you will be able to see the O-ring still in position on the water pump housing. This is after the thermostat housing has been removed.
