overheating

[JAY ST]

i need some help.

i have a 2.0l zetec engine in my mk2 escort that after letting it run for 5-10mins to wam up, the water temperature reaches 100 deg c and is still climbing.i have taken the thermostat out and manually switched on the fan but the same thing happens.i then took the radiator cap off and started the engine,it looks like the pump is working as water is moving in the radiator.the same thing happens.the engine is running fine and theres no gunk in the oil cap or i'm loosing water.

would a different rotational pump be the problem i.e one off an escort zetec not the standard mondeo item. OR IS IT HEAD GASKET FAILURE!

 

if it is head gasket failure how difficult is is to change?

i know very little about zetecs but dont some of the water pumps run the wrong way? so yes there may be your problem

[JAY ST]

i might just buy a new escort water pump and belt and see what happens then.

cheers

Are you hooked up to a standard escort instrument panel and if so have you got the right sender unit for your temperature gauge?

 

Try measuring the temperature of the water at the inlet and outlet of the rad and see how it compares to the figure your gauge is giving you

[JAY ST]

I have a seperate temperature gauge as the original gauge on the instrument panel has been disconected, also both hoses are boiling hot.

Both hoses are boiling? you're not getting any temperature drop across the rad?

[bomber1]

is there any cold spots on the rad?

[JAY ST]

i"ll have to check again with the radiator to make sure that there are no cold spots.i"ll keep you informed.

mate i know for a fact you need the correct water pump with the right rotation, i think its the one of a zetec 1800, the 2 litre one wont work

[JAY ST]

thanks mate i'll give it a go with the water pump.
