water boiling over

[Adam*FR*]

Any1 had this problem think its because of the heat.
Eariler after parking my car heard a hissing under the hood, opened the cover and the water was boiling and i hadn`t been booting my car at all.
Check the water levels they seem ok now but i put my foot down earlier and it lost power any 1 got any ideas
It is due a service aswell

Are you not using coolant ?

What was your temp reading ?

Was the radiator fan running ?

Had it lost the power once it had cooled down ?

Have you checked your oil to see if water is mixing in there ?

Any other symptoms ?

fan was running
the temp reading was on 90
lost power after i booted it up the hill after about 4500 revs
not sure on the rest think its best to get it down for a service
any advice would be appreciated guys

well it cant have an air lock as the fans where running


better get it in for that service get them to diagnose it mate

if the car was still running when you looked under the hood and the fan was running did you have the aircon on as the fan will be on consistantly with air con on!

there is a pressure relief valve built into the coolant filler cap

these can develop a fault and become stuck open, this causes the coolant system to loose pressure and then the coolant can boil away

fit a new cap as they are only a few quid, you never know

failing that it sounds like you have a faulty thermostat, fan switch/fan or a leak

do also check for signs of brown shite in your coolant tank and/or creamy shite on your oil filler cap

good luck
