hello

just wondered if any of you mechanically minded peeps have any idea of how to solve a problem i have?

 

i have a mondeo and the heater works well but it comes out hot for a time and then goes cold:confused1:

 

does anybody have an idea how to stop this or why it happens?

 

all answers welcome thanx

its a ford :)

 

Someone will know no doubt

mark, are any matrix pipes collapsing as it gets warm i wonder? maybe it has a thermostat in line which is fooked and shutting off....water pump could be on its way out another poss...or the matirx is silted up with crap and so wont pass water through

 

cheers

Actually my zed does this occasionally, and when you are stationary it goes cold sometimes, then hot again when moving, so maybe not an uncommon problem among other car makes.

I really need to flush the rad and engine as the water is a dirty brown, so that probably doesnt help the heat flow lol

thanx guys

think i might try flushing the system see if that helps

Yep , sounds clogged up to me . :thumbup:

clogged up, air lock, not enough water in
