Good one. Like the improvised cookware. Could’ve had a coffee afterward.
I think I’ve had about 10 Toytos and Hondas after my air cooled 1966 Beetle.
I’ve been lucky never to have had a thermostat problem. I’ve always bought new cars, and used the car to extinction (the dump). But I’ve kept the coolant reasonably fresh throughout their lives.
Do you think thermostats fail due to too many cycles, poor manufacturing, or ugly corrosive coolants? Thanks.
This is great. I had a question on this I’d been wondering about.
I have a 2003 PT Cruiser. It used to have the cheapest antifreeze money could buy in it. It wasn’t overheating but the antifreeze had been in there for 5 years and where I live it is often -30 celcius at night. So I took the old antifreeze out, flushed the system with water and filled it with the factory recommended HOAT antifreeze (can you do a video on what the hell HOAT is and why it is supposedly better?) So now that I’ve got the HOAT in it it’s doing something strange. It gets up to operating temp and whenever the fan kicks on, which I’m assuming is tied to the thermostat, the engine temp drops quite a bit (on the temp gauge in the dash). With the old stuff in it it never moved once it was heated up, now it will show a drop in temp of about 1/8 of the distance of the whole gauge when the fan comes on and then creep back up to the middle (operating temp) in a minute.
Is this fine? A sign of doom? Did I do something wrong when I switched antifreeze?
The HOAT I bought was the premixed Zerex G-05 brand. The reservoir is showing the coolant is at exactly the right level.
Thanks
My vehicles seem to run a few degrees cooler on HOAT as well. Weird because the difference is just the additive package for anti-corrosion and what not. I figured it could be a different concentration of antifreeze/water that is affecting the cooling properties.
Very good video Eric!! I’m looking forward to the new video series you thought of and i also cant wait to see more of the Fairmont!!! hows it treating you so far

To answer your question I would say, all of the above.

It doesn’t sound like there’s anything wrong. The new coolant, or the mix you have now, sounds more efficient. Unless it’s overheating or staying in the cold range, I wouldn’t worry about it.

Look for Fairmont stuff more towards the spring. I have a few other things I want to cover first. I also want to wait for some warmer weather. It’s been brutally cold at the shop lately. Not very good for shooting videos.
Yeah, what makes a thermostat work is wax. Well, that and a spring. Liquid wax has a much greater volume than solid wax (however solid wax gets). All the manufacturer has to do a brew up a wax mixture that melts at the required temperature and you have a working thermostat. The energy required to make this little motor work comes from the coolant.
A thermostat is opening and closing continually most of the time when the engine is operating. It is a moving part and moving parts wear out. Hence it is a good idea to buy a good one.
