Engine Running Hot
My stock 292 is running hot, 210 on the road and close to 230-240 in town. I am running a 50/50 mix, I took out my 160 thermostat thinking it may be stuck, now it just takes longer to get hot. I do not have shroud and don't even know it inline sixes used them. I don't feel any cool spots in the radiator and have replaced the cap. I seem to loose anti freeze slowly, I don't see that much out of the overflow tube. No smoke or steam can be seen in the exhaust, and there is not water in the oil. Timing is a little advanced, set for 4500 ft. Any ideas anyone? Can the water pump be pumping too little water? Thanks,

Re: Engine Running Hot
Plugged radiator or cap that won't hold proper pressure, loose belt?

Re: Engine Running Hot
I replaced the cap (used one) but no change and I thought that by feeling the radiator for cool spots would tell me if it was plugged. With the six it is easy to get out anyway, the radiator shop can check that.

Re: Engine Running Hot
I'll bet with a good professional boiling out, new thermostat and cap, you won't have anymore problems.

Re: Engine Running Hot
I was having a simular problem, I turned back the timming and that seems to have helped a little, also I have been told that different spark plugs also fire at different temperature ranges of some sort.

Re: Engine Running Hot
I would have the radiator checked......donuts to dollars...thats your problem.
With the thermostat out...open the radiator cap and make sure the water pump is moving the coolant...if it is....I would pull the radiator and go have it checked. If you have an extra radiator or a buddy close by with the same kind of truck....swap them out and try a different radiator. it does not have to be an exact fit to test it. I have had 2 start to warm up this summer alone and clogged radiators were the culprit in both cases. I keep a few radiators on the shelf for that very reason.

Re: Engine Running Hot
Thermostats DO go bad... mine just did.
Also, check the hoses and make sure they're not collapsing. As someone else said, it could also be the timing. But, if you said the coolant seems to be disappearing slowly, and you don't have any drops on the driveway, you might have a head gasket issue. -Brad
