Summer's here...Cooling system almost perfect!

[ps2cho]

Thought I'd post this here so you guys know what your M103 cooling system should handle. Lots of posts here with members saying running up to 110C is OK -- No, it is not. If you are hitting this mark, you better have ambient temperature of 130F or start diagnosing right now since you are accelerating metal wear.

This is A/C on after a 30min, 20mile drive 110F ambient. Once I get my A/C back in order it should run a little cooler too since the condenser is running at high pressures and in turn raising my temperature.

Aux fans are running on LOW with A/C on, 79C thermostat, Nissens Radiator (10k on it), Graf water pump (30k), Zerex G-05 + distilled water roughly about 40% concentration that's all cooling replacement I've done. No water wetter garbage. Just a pressure tight, flowing system.

Happy summer cooling!

Thanks for the detailed setup. What's the 79C thermostat you're referring to? I assume it's not the stock version? What's the part # and / or where you got it from?

Thx

Stock version is 87C, but Behr makes a 79C. No issues running it. Obviously if you live in cold climate don't do it.

Part # 1002000715

Why not if I live in a cold winter climate (summers are hot though)?

[ps2cho]

If your summers don't exceed 90F, you don't really have a need for it.

Ok thanks
