did a few checks last night like oil and water on the Cabby as it's the first outing this weekend, took it across town to get some fuel, drove well. But when i parked up at home i could hear the fan running, i flipped the bonnet open and the expansion bottle was hissing like a good un with signs of water leaking out. any ideas where i should start..?????

did you bleed all the air out of the water system? If not its a good place to start, fill it up, expansion tank cap off, heater all the way to full and on maximum fan speed. Keep doing it till there is no bubbles coming up in the expansion tank, heater blowing warm and the fan has cut in no less than twice.

Squeeze all the pipes especially the top and bottom rad pipes quite a lot to help release air locks.

If you've done above ^^^, it could be a dodgy header tank cap

i'll try this when i get home from work, I'll keep a bottle of water in the boot for the Convoy to players 2moro just incase.....

right, i ran engine with cap off, heater on full, didn't see any air bubbles but left it running anyway for about 25 mins. As soon as i shut the heaters off and put cap back on the temp needle climbs to half way mark, the fan cuts in and the water bubbles out

i hate to say it but sounds like the water pump, with the fans on your desipating the heat enough, got a mate that had the same prob on his seat ibiza it would just over heat without the fans blowing hot air and his was the waterpump,

tinks

i'm gonna chance it and driver to players 2moro then get it sorted next week

hello mate how did it go, cant recall seeing it there but thats probably me just not looking lol

well i made it there and back, had to have heaters on full all the way to stop it overheating. I was parked right behind the Fendubbers Banner about 5 cars up from you (next to the polo with the teddybear rims). reckon it might be a trip to the garage to have them take a look

haha yeh i remember lol iv got the mind of a gold fish, well lucky u got there and back, does sound like the waterpump best get it in the garage dont think there to expensive,

good luck with it mate
