Question about 1994 Lincoln Mark VIII
I need help. I have a car that overheats. It will not cycle the water through the engine. I have replaced the thermastat, water pump, both looked super clean. I have flushed the radiator, no clogs there. The fan kicks on as usual. The car has full power. No water leaking, no moisture at the exhaust. What could it be? I was told a possible heater control box but I don't know where that is or if this could cause the system from cycleling the antifreeze.
Did the radiator check out ok, if it is ok then you might have an air lock in the cooling system, try loosening the coolant sensor or remove it while adding coolant engine should burp large air bubble then start to ake more coolant, how much have you put in, get back to me if you still need help, i strive for the best Ray

The only thing you haven't replaced is the heater core, however even if that was plugged your engine still would not overheat because the heater core is on a by pass hose. my question to you is was the theromstat installed correctly? is the belt that rtuns the water pump routed correctly so that tyhe pump is turning the direction it should. these may sound like stupid questions but have know to happen. the sring part of the thermostat should face towars the intake of the engine if it is installed incorrectly it will cause no circulation of the coolant.like wise with incorrect routing of the belt if the water pump is turning the wrong way no coolant will circulate like it should. what can also happen is the replacement pump and/or thermostat were deffective. there is a such thing is the term "brand new junk" I can't tell you how many times i have replaced parts just to find out that they were deffective. my advice is to look over these area's again. if all is in order feel free to contact me here just click my user tab
