Thermostat Replacement

[356to966]

My wife's 02, Tipronic, Cab had a cracked cylinder engine failure a couple of years ago. I don't know what caused the problem outside of the former owner not being at all car savvy and all that implies. We surely don't want this to happen again so do all the little things to maintain and operate the car as it should. I've been wondering if a low temperature thermostat would help but delayed so as not to jeopardize Porsche's two year warranty on the new engine. My question is; how much coolant should I have on hand to replace that drained out during the thermostat R and R process?

Thanks for any help and also to all that contribute to this extraordinary forum.

I would wait till the warranty is over before this mod (or any orher mods), which likely will void the warranty. AFAIK, cracked cylinder is not a common mode of failure on the 3.6L. I think we see a lot more posts on scored cylinders.

Just change the oil every 4-5k/6 months whichever comes first. Easy on it when the engine is cold and never lug the engine. Reman engine failure is quite rare.

Forgot to answer your question. If you remove the coolant drain plug, about 2.5gal will come out for a stick shift car. Your's a tip so it may be a little more.

So I think you would need about 1.5gal of pure undiluted coolant.

Thank you Ahsai,

I pretty sure the former owner of our car didn't follow you guidance in your first reply. Hence our engine failure. Your advice to keep the revs up is particularly good for anyone with a Triptonic transmission. The Tip will default to shift at ridiculously low RPM when operated in automatic mode. You can teach it to act more sensibly but that takes a warm engine and a place to use full throttle. Because of this, we always operate in the manual mode and shift with the steering wheel buttons.

Thanks again
