Engine Cooling problem
1999 Ford Escort 4 cyl Front Wheel Drive Automatic 128000 miles
most say that the coolant can be drained through the radiator petcock, and to do a little better job a block drain plug can be opened if available. According to some manuals my car is suppose to have a block drain on the exhaust side but it sure isn't there- I checked and rechecked. Anyway, I tried draining thru the petcock but only about a quart came out. I replaced the quart with an extended life antifreeze which the manufacture said would replace all colors of antifreeze. Now I would like to flush the engine and replace the antifreeze. Since only a gallon came out of the petcock last time i'm figuring the radiator is a little blocked up near the petcock. Must I remove the radiator and clean it, or is there an easier way such as taking off the bottom hose and draining the engine, and then run water thru the radiator with the bottom hose disconnected - might that suffice to clean the radiator? Or could something else be the problem? Should I refill with extended life, and are there reasons why the extended life might not be as good as the original green?
also the cooling system is supposed to have a float/seat de-gas system to aid in filling. What is this?
have the same problem?
