How do you drain the engine coolant in 1990 Chevy Corsica?
Place something to catch the engine coolant beneath your 1990 Chevy Corsica radiator. Remove the radiator drain plug with a 9/16 ratchet. The engine coolant will drain out.
Where on the engine block of a 1987 Nissan maxima are the coolant system drain plugs and after you flush the system do the drain plugs have to be replaced?
It's on the bottom of the radiator, and there's also a coolant drain plug somewhere on the block, but I've never flushed the coolant on mine, so I don't know exactly where. Don't forget to let the engine cool COMPLETELY before you do this. It's not just a matter of you getting burnt, you could also damage the engine if you drain the coolant or oil while its hot.
Your 1994 Chevy Corsica is pouring antifreeze for below but not out of the heater core what is it pouring from?
You will have to drain part of the coolant. Try to drain as little as possible and fill up before restarting the engine. No, the thermostat is usually at the top of the engine block (placed between the top input hose and the block). If, however, the radiator is full of coolant, there will be some spillage. Also, make sure the coolant has cooled down before replacement, and do periodically replace the coolant as needed.
