Just have an issue with my dad's 1994 Camry Vienta V6. It currently has 156,000kms.

The radiator has been replaced 2 times due to the top tank leaking.

Straight after replacing the radiator, we've used Toyota coolant and bled the air as usual.

Problem goes away for about 1 year then, the top tank begins to leak again.

There are no overheating issues as the temperature needle stays on halfway when at operating temperature.

The thermostat has also been replaced.

I've narrowed it down to the thermofan switch. I've noticed that when the car is started up [even when cold] the thermofan spins slowly and I've never heard it kick in.

Just need a few opinions on this issue and whether or not anyone else has had similar problem.

I had a similar problem with mine only a few months ago... found that the radiator fan wasn't spinning like it should be (you could actually grab it). It'd heat up on idle, but drop back to 1/2 way when driving.

I took it to the Mechanic... got him to check it out, showed him the problem and everything... he thought maybe something got caught in a sensor or something like that, or that the thermostat was stuffed.

I ended up goin back in the arvo... asking what the problem was, and he said at that time, he couldn't fault it. The fan was goin nuts like it should be and everything was back to normal... I've never had the fault come back since.

I asked a few people... I found that maybe, just maybe that the power steering fluid might have something to do with this, as it passes through a welsh plug on the radiator fan. Maybe the fluid is old, not doing it's job or something like that, and could cause the problem?

Either way... that's another place to check mate.

as well as what was said above, I've heard of radiator here in the US constantly going bad due to the fact the replacement radiators are pieces of crap and bad quality.

      overheated engine

      I drive a 2010 series 200 sahara V8 automatic. I recently towed a small caravan on a not that hotter day. The temperature gauge went to about half then dropped back to normal. The motor then went into limp mode and eventually stopped. On lifting the bonnet i noticed the top radiator tank had split all the way across. I have only two months ago had the complete cooling system checked with no defects. I called the RAA in South Aust and they tried to start it but just turned over but did not fire up. It was still pretty hot. I have been told the motor would be ruined by overheating. The car has been sitting at the repairers for 5 days now and as far as i know it has not been attempted to start. Before putting a new motor in it would it be worth putting a new radiator in it and see if it will fire up? Open to any suggestions at this stage.

      1996 Trueno XZ - Is it worth modding?

      Depends on how common/rare they are in your part of the world. The XZ trim was the second-lowest so didn't come with most of the fun bits that the full-fruit BZG/V/R models did, so it's not anywhere near as desirable stock but sometimes you have to make do with what you can find, plus you shouldn't feel as guilty modding the heck out of it since most of it isn't special.

      VSC, Traction Control, Check Engine lights all on

      I attended Toyota Preston for Aurion ATX 2013 major service today. Cost $~$1300. On the way home I stopped to pick up dinner. Two fault lights: engine and VSC lights came on when I restarted the car. Car drove home just fine. I can only return the car tomorrow for them to sort out. Annoyed. Let’s see if they’re still on in the morning.

      Hi everyone, new member to the group and owner driver of a nifty little Toyota Sprinter Trueno XZ, now this was my cousins car, I bought it off him and after various drives, I have come to the decision that this needs alot of love. Now I am wondering if its worth putting my time and money into doing this certain make n model up or should I just buy a different car to do up? I am not very car-inclined so I really don't know a lot. Any opinions would be very helpful Thankful!

      Android auto

      OK. Does any of Toyota's advertising material mention Android Auto? If so then kick up a stink, with Toyota management, about misrepresentation and false advertising, reminding them of the hefty fines. Herb
