right, i shall start from the beginning. i changed my fan belt on monday,as the old one was frayed and really old. had to undo the top rad mounts to get the old belt off. fitted the new belt, put the top rad mount back on. ever since the temp guage has been fine for bout 20 mins, then gets really really hot, but the fan heater inside the car is blowing out cold air????

undo the the rad cap - no water?. water spray all over the bonnet, and every where inside the engine bay. the thermosat houseing is boiling hot, but the rad isnt the warm???

so i took my rad out today checked it all - fine (has onlt been in for about 2 months) checked all the hoses - fine - flushed the system, and put it all back together.

went out fro a test drive - fine for about 20 mins - boiling hot again - exactallyy the same thing no water in rad - water spray in engine bay - thermosat housing boiling hot? filled it up with water, and there was a little stream on the road? but still rad was full?

strange or what? any ideas?

Thanks

well for starters you ned dto be putting coolant in there as well as water even if it's throwing it out.

Thermostat could be stuck closed, hence water isn't being let through to the rad to cool, pressure gets too high,


splurge...........

yer was puttin antin freeze in aswell .

thought it might be the thermostat - but just put it up incase anyone had had the same prob and found it to be summit else

the water pump seal could have gone, check for a drip from around the water pump!! only a slow one but once at presure is more of a trickle!!

[JoeBodge]

right ok - is that a big job to replace?

[fikus01]

remove rad and fan and 4 bolts and the pump is off and your nice new antifrese is drained again!!

[JoeBodge]

can you get a seal from unipart or halfords? do i just put the new seal on and put it all back together? or change the whole unit?

thanks

morning mate. if it's the water pump, you just replace the whole pump, i aint heard of anywhere selling the seals to go inside.

[fikus01]

new one and make sure its a solid cast impellor not a bit of bent metal!! they are useless!!

[JoeBodge]

changed the water pump and thermostat - has been fine since (touch wood). thanks for your help:D:D

glad to hear you managed to change youe thermostat without shearing any bolts /studs!!!! i'm not bitter - MUCH!!!

[JoeBodge]

lol - they were only undo about 4 months ago - lackered up with sum copper grease - easy to undo

[mark clark]

well they've now been replaced by a stainless steel stud kit from Minispares - a bit pricey at £18 but very sexy and no more probs with snapped studs (fingers very tightly crossed)!!!
