Boiling up

[aerosam]

Hi guys, I ran my engine up to temperature today, to ensure the temp guage is working and to recharge the battery.

After 20 mins of idling, the expansion tank boiled up and water flowed from the overflow. However the radiator remained cold, along with the bottom hose. The top hose feels empty.

I'm suspecting a stuck thermostat? Any other ideas?

yep... would say stuck stat as well... take it out and chuck it in some boiling water cool it under tap ....watch it to see if it opens(in hot water) and closes (cold tap) repeat several times to 'break' it back in, then check opening temp by gradually heating in water.
if fubar'd buy a new one ....they are only coppers
oh forgot to ask....your water pump is working isn' it ?

Haven't checked water pump yet, but will do.

I'll definitely be pulling the stat out and checking to see if it's working or not. Just priced a new one, £52 inc VAT from my local motor factor! Was quite a funny phone call actually, they needed a registration number to identify the exact model of BMW I had so i gave them the one of the donor. The line went very quiet for a while so i asked if I'd got the number right, and explained i wasn't sure as I'd broken the car a couple of years ago.

With a huge sigh of relief, the lady on the other end says "I'm so glad you told me that, I didn't have the heart to tell you your car had been scrapped!"

Hmm, might try that first actually. As I'm guessing it might be easier.

I'll take the rad top hose off and make sure it's filled with water then try again.
