having a problem with my zetec turbo geting too hot so i removed the thurmostat and it didnt make much diference at all! apart from it would take about 10 miles to warm up!

even crusing at 70 mph with the stat removed the temp guage is just below half way and rises if its under load

could a blocked up rad cause this?

and is there any stuff i can buy that can clean out the radiator?

i bought the car as a non runner to install the engine in to so i dont rearly know how it cooled before

i have a front mount pro-alloy intercooler and in traffic the fans cant seem to get the temp guage below the 3/4 mark

also if i boot it for a minuite the temp will go up to the red then then take 5 miles of light crusing at 50-70 mph to get to half way on the temp guage

in traffic if i put the heater on with the blowers it makes quite a big diference

just wonderd if you lot have come across this sort of thing before and how you fixed it

 

one thing what most people do, is the wiring on the fans has to be correct, if not the fans will suck rather than blow!,

taking the stat out isnt a good idea

having a good rad is also a very good idea with a front mount i/c in front of it,

Also the normal things like water wetter in the coolant, heatwrapped exhausts etc can help loads

 

cheers i will have a play tomorrow

 

dont take the thermastat out it helps to slow the flow of water down to the rad to give the water time to cool down before it enters the engine again.
check the stat is in good working order and make sure the rad is good try back flushing it ect. also another thing to bear in mind is the cam timing if this is out then your car could cook. or even go for a charge cooler to give more air flow over the rad.

 

i have a front mount cooler , and when i 1st used the car it used to run very hot , now i have fitted an alloy rad and used bonnet lifters, also i have wired the fan to a switch , it now sits BELOW half way , boost or no boost it rarely goes over half way , im not using water wetter either

 

i have a GRS front mount intercooler with 2 kenlowe fans and it never goes above half way on the temp gauge no matter how hard i drive it

 

Dude you havent done something silly like got a Mondeo waterpump in there have you? If so, its spinning the wrong way and pumping fook all May be worth a look?

 

i hope fooking not

 

my zetec turbo was like this as well with a front mount i/c. bit of a pain. i was still using the standard cooling fan so that is what i was blaming!!!!
