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!
