Over Heating Problem

[Guest]

Have a 1927 Buick Standard that over heats sometimes. The ignition timing is right on had numerous people check it. Fan belt is tight. Spark advance is fully advanced when driving. Rebuilt water pump. Radiator flows empty in 10 seconds(maybe this is too long???). Now as long as the car is driven on flat it is ok, but when there is pull on the engine like going up a hill the temp gauge goes up then when it goes down the hill and I let the engine breath the temp will go down a little. Also after driving it, and I turn the engine off the radiator will bubble up and some collant will bubble out the neck of the radiator. I am running 60/40 antifreeze and water in it. Also the air temp is 60 to 100 degrees. Now 100 degrees may be too hot for this car to run, I don't know maybe they didn't drive these cars back then when it was 100 degrees but I find that hard to beleive. Thanks in advance for any light that any one can shed on this problem.

Perhaps it's not the motor but somewhere in the drivetrain that is not performing as it should and therefore putting extra load on the motor when going uphill ? 2 cents worth.<BR> Doug

Does the car have a Coolant (diverter) tube in the block? Did you check it? If the tube is damaged, it will cause hot spots in the engine and cause it to over heat. Also, If you have a thermostat, is it working properly. Is the engine running to lean, when was the last time you flush out the block? Also, ars the brakes dragging? This is just a start for thing I would check, hope this helps.

Perhaps the water holes in the engine block are clogged with calcium carbonate which not allows the water to flow complete through the engine. <BR>That the radiator is empty after 10 sec. means not that all fins in the radiator are free.<BR>Normally hot temperatures are not really a problem. I own a 1930 Buick with the large engine and a 1912 Cadillac. I never had problems with over heating even in city traffic and up to 90°. Last tour with the Buick I had the radiator shutter just 75 % opened and it went not hotter than 180° even in low traffic. Normal driving temp was 160° (actually too cold). Outside temp was 90°.<BR>So I think there is a technical problem at your car. No questions of the age of these cars.<P>Tom
