1.1 saxo overheating
Hi everyone,
Ive got a 2002 1.1 saxo which is overheating. If im driving with the heaters off the coolent rises quickly and starts leaking from under the rad cap but with the heaters on it takes longer to start overheat. I've opened all the bleen valves filling with coolant (while squeezing both rad pipes) until coolant comes out of all three the done then up started the engine and continued filling until the expanction is full so its not an air lock.
Secondly ive replaced the thermostat as thought that could be stuck closed and lastly the heater matrix isnt leaking at all. No oil mixing with water so wouldnt say its the head gasket.
So the coolent just rises and starts leaking from under the cap after about 5mins of driving from cold.
Does anyone have any other ideas i could try?

Are you overfilling it?, it only needs to come halfway up the filler pipe on the radiator, between 6 and 12 inches below the cap level and it's difficult to get the water out of the filler neck when you've finished filling it.
After the initial expansion water won't continue to come out of the filler cap as there won't be enough water in the system.

Sounds like a hgf to me but...... Maybe try just replacing the rad cap first! Think mine was about 5 quid on eBay or get one from scraps, they may just say take it!
Only other thing I could suggest would be to flush it all and refill it

Just a quick update, I've flushed the cooling system and has made no difference also the bottom radiator hose has started getting really hot is this something to do with it?

Sounds like the water pump is buggered, if the water isn't being circulated by the pump it will sit static in the plumbing until it heats up and eventually causes the water to boil, which is probably why the water is coming out the cap because the expansion of boiling water is pushing water out from the cap... I'd take the water pump off by the belts and test it whilst off the engine and see if it needs replacing

Could also be the cooling system is being pressurised because of head gasket failure,mine did the same thing.

Fingers crossed!
I thought maybe water pump but surely if the water pump wasn't functioning right it would cause the heaters to run cool right?

You'd of thought that spendyrx but if the pump isn't pulling any water then the heat won't be dispersed evenly and will boil I suppose

Yes considering they'd have to replace the cambelt and tensioner at the same time.

Do you know it's 100% waterpump? Maybe worth getting a hydrocarbon dye test done first to see if the heads gone, it's gonna be cheaper than getting the water pump done! I know either way you're gonna end up replacing the waterpump but still its better than paying double the Labour charge of stripping heads/belts etc!
Not a bad price though for Labour and parts!

I have the same problem after changing head gasket,coolant is boiling fan works too short I suspect it could be the thermostat.Water pump has not be changed but I don't think it's causes this.
Any ideas?

Have you given the cooling system a good, thorough flush? I managed to get my hosepipe sealed to various parts of the cooking system and flushed through in both directions.
Also, did you bleed the system at all of the correct points?

Does sound like head gasket starting to fail. There are a few quick tests you can do:
After a drive, squeeze a few of the coolant hoses, are they rock hard?
Take off radiator cap (when cold) and have a sniff, can you smell petrol? Can you see tiny black flecks in the coolant (carbon deposits)
Leave rad cap off an run engine. If you are getting regular bubbling that's combustion gas escaping
I would try all these before going ahead with the water pump as the head will have to come off anyway and the pump and belts can be done as part of the same job
