that sounds sensible

How does no thermostat make it overheat? It just leaves the rad open all the time, so it will take ages to warm up, but this will make it harder for it to overheat. Yes it would use more fuel though.

The thermostat is at the entrance to the radiator, and opens gradually at once the engine is up to temperature, so it keeps the radiator closed when the engine is cold so it heats up quicker, then once up to temp opens to keep the temperature down.

mine sits about 87 with a 1.4 8v rad on and a cool running stat. fan cuts in at about 98.

now u asking lol, in some it diverts the water thro heater matrrix or the rad, not tooo sur eon a corsa

how exactly does the thermostat operate in an engine?

hmm ok

1.2 rad is fine for it as its the same size as the 1.6's if they didnt have aircon

i wish i had an xe lol

isnt the 1.2 a little small for an xe???? i throght u might of needed a bigger 1

ok ill get a new one and see how it goes. have u got an xe? if so wot rad u using?

nope hotter, it makes a big diff, annnnnnnnnnnnd it can make the ecu run on the "warm-up" map longer... soo hence hotter also, but yeh it can effect running temp alot!

didnt think this would make it run hotter, cooler if anythin i would have thought

mayb thats ya prob then mate

fna does come on temp goes down slightly then gets hot again. theres no thermostat in at the mo it nackered just bout to buy a new one

id check the thermostat,water pump, and if the fan comes on

Whats the normal running temp for these, and what rad should i be using, currently im using the 1.2 rad with gsi header tank(2inlets at top) and it runs very hot and it even blew a few water hoses

thought about getting a diesel rad or out of a combo van as these look thicker

can anyone shed any light on this or is there somethin seriously wrong?

Cheers
