I purchased a cambelt kit etc etc from Toyota North western last year, january. Installed it all, on my engine and put the engine in the car.
Didn't even get to drive the car 100kms in total before i had to part the vehicle out.
Now, i had another vehicle, same car (my current mr2, 3sgte). And this car was due for a coolant flush and my thermostat seemed to have siezed open. So i thought hey, it'd be cool if i rip off the new thermostat off the engine i took off the parted out car.
So last week, i took it off, but found that my current one in my mr2 was a 82 C thermostat and the one off my old 3sgte is a 72 C one. I thought this was a bit funny as I don't think toyota would have given me a wrong part.
I flushed it for around 30 mins (didn't flush the heater lines or cores tho), got red "Nulon" coolant and poured it in, and assembled with the 72 C one which has less than 100kms on it as mentioned above.
Bleed the cooling system, and car heated up to temp pretty fast so was happy.
Went for a drive, then noticed the temp just went down again as if it had no thermostat.
My questions, -
1. Red coolant, and Green Coolant, i heard you shouldn't mix the two? My new one is red and old one was green
2. which one would be the correct temperature? 82C or the 72C
3. would a thermostat become buggered if it's been not used for nearly two years after being first used?
4. How long does toyota provide warrantees for on parts the sell?
