[tay14]

after 8 months of trouble free driving on my way home yesterday my mk2 escorts temp gauge started to rise to max,all the hoses were hot top,bottom,all heater hose and the cars heater was blowing warm but the radiator cap was stone cold.i let the car cool down at home took the cap off to check the water the level was spot on,theres no leaks any where and the thermostat works fine. any ideas? cheers as i was going to the yorkshire meet today.

I'm having the same problem with my x flow its gets so hot. So far I have replaced the thermostat, put on a new radiator and fitted an electric fan kit.

 

Yours sounds different though, to just suddenly happen if its been fine before. Maybe the water pump has failed? or an air lock

 

Have you tried running it again since it overheated?

get a new rad cap sounds like its not holding pressure

the cap is a new one about a month old ,ive just had all the hoses off and flushed the engine and rad both ok,the water pump is working.also just done a compresion test thats spot on too.got the car warming up know running spot on.

i would check your thermostat is still working.....i had 4 new ones stop opening on me ....last thing i tested has they were new.......im now running without one

[tay14]

thats what ive just done,ive taken it out and the car runs fine just the temp stays really low now ,but it will with no thermostat in.i tested the thermostat 1st and it opened fine ,must be sticking now and then.Will it affect the car by having no thermostat in?

engine will run without a thermostat alright, but best to get a new one
