i've had my radiator re-cored, to a high flow, pull out the thermostat, the strange thing is some times i check the coolant level and its fine, once i checked it and i had to add a gallon of coolant, and then there is times when i check it and the coolant is all foamy, anybody got a clue what my problem is?<br><br>the car always smells hot when you open the hood.

Check your clutch fan and your compression.<br>It sounds like you have an internal boil over which can indicate a weak gasket or even bad valves. Make sure you also bleed your radiator when you add water/coolant. Another thing you should check is your radiator cap and if you can, you can also flush your engine through the block.<br>There is a drain plug on the side of the block under the exhaust.
