My 89' RS 2.8L heats up for Everything, i'm running a 180 Thermostat(working), put a new radiator(working), flushed the engine, changed the cap, it has enough coolant, and the water pump is working cause i let the top radiator hose open and when the thermo opened all the coolant came out(don't worry it's back on) HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11[:@]

 

do you have electric fans?also check your top and botom water hoses.might not leak but if they are old they colapse on themselfs and stop the flow .let the thermo open and give it gas,see if the hoses are ok.also check your guage make sure it works. keep us posted....good luck!

 

thanks so much, i'll be surew to check that, keep you guys posted, but be sure to check
