Hi everyone, just joined after lurking for ages! Love this forum & site!
Heres my problem...
I have a mk1 orion 1.6i and it keeps losing water after almost every run. I've just put a new radiator, thermostat, 1 new top hose and it still does it.
The water seems to come out of the overflow pipe only when the fans on and after its turned off after being hot and it seems to drip out for at least a minute after the engines dead! Could this be a dodgy header or blockage in engine or maybe in need of a new temp sender? I don't think it could be the head gasket as the engines been reconditioned some 15-20ish k ago.
One day when i have the funds I hope to get it resprayed in diamond white, with body kit and rst lump in.....after all the rust is sorted!
Oh well,
Any help would be really appreciated!
Cheers,
David

Head gasket? (pressurising the water system and pushing water out of the expansion tank?)

Nice car you have! Mine does the same also if I keep the water level between the min and max. Now I'm running it just below minimum and it's fine. It's a feature of the expansion tank cap to let pressure off too easily. During the summer I ran the car with the ignition relay removed and shorted with a jump wire. This way the cooling fan keeps cooling even after you switch the car off untill the temperature comes down.
My temperature issues are mostly turbo related and I didn't have these with the standard engine ever. So you might wan't to flush the radiator and change the thermostat just to be safe. If your having any temperature problems while driving or oyur fan kicks in too late, then I can warmly recommend the Toyota 82 degree thermostat. It opens slightly earlier than the original one and when it opens, it opens way more.
If you can you might want to try another expansion tank cap if you cap.

Thanks for the replies.
My best bets to take it to a garage...
I'm still not sure its the head gasket thats gone as I checked the oil the other day and just a good gold colour with no mayo/water signs.
Jesse, got anymore pics of your Orion?

Cheers

No not really. I have lots of pictures of different parts and details, but nothing about the entire car that would be up to date. Even the picture in my sig is taken well before turbo time. If you have something specific in mind, just e-mail me: jesse.tuominen .....

Oh well not to worry mate.
By the way took my car out today got caught in road works and the dreaded light came on after we were on the move. Stop to fill up with water, drive down to halfords to get a few bits & bobs and waters dripping out again after engines off. When I get back home I look under the bonnet and the header tanks rumbling like mad!
Closer inspection and I see the fan wire aint on the thermo housing! What an idiot I am lol! This should be moved to the muppet bit! Hopefully (touch wood) thats solved. It used to lose just a little bit after a long run with a pretty bad condition radiator. Its got a brand new one in now and a new thermostat. The old thermostat was a pig to get out! Whoever put it in before managed to get the metal clip under the rubber washer type thing for the thermostat! The rubber was all corroded too so I had to keep scraping it off with a screwdriver until It looked suitable.
I'll try and put a pic up in a min but its totally standard looking apart from clear indicators and a Kissfm sticker. lol
Anyways thanks again for the help.
cheers
