Dav555 Posted June 25, 2016 Posted June 25, 2016 Hi my Impreza has just started over heating anyone got any ideas? The water looks like it's changed colour . Thanks
GeoffLeggy Posted June 25, 2016 Posted June 25, 2016 What colour has it gone, brownish? Are you loosing coolant? Is it overheating when moving or just stand still? Have you checked the oil dipstick? Any smoke from exhaust when warmed up? Sorry for all the questions but will help with diagnostic.
stants Posted June 25, 2016 Posted June 25, 2016 How badly ? Any visable signs of leaking water ? Pinhole cracks on the radiator are common on stock units. Could be something as simple as that or a broken thermostat, worst case it's head gasket related Sent from my SM-G930F using Tapatalk
Buggyeye Posted June 25, 2016 Posted June 25, 2016 Your oil is contaminated with coolant. Worst case is blown head gasket or cracked/warped head
Dav555 Posted June 25, 2016 Author Posted June 25, 2016 Yes looks brown ish not losing water. Temp is OK while moving fan kicks in temp keeps rising while standing iv not let it boil took it home parked it
Buggyeye Posted June 25, 2016 Posted June 25, 2016 Could be really dirty coolant. When did it last get changed.?
Dav555 Posted June 25, 2016 Author Posted June 25, 2016 It's booked in for a service Wednesday, I checked oil and water the other day it wasn't brown then
Scoobyghost Posted June 25, 2016 Posted June 25, 2016 Check the inside of the oil filler cap. It nay look like cottage cheese. If there is a the white residue that's a sure way that water is in the oil system.
Buggyeye Posted June 25, 2016 Posted June 25, 2016 If it's happens that fast then it doesn't look good. How far did the temp gauge go?
Dav555 Posted June 25, 2016 Author Posted June 25, 2016 No white crap on oil cap, temp went up to just before red, iv got everything crossed its not head but knowing my luck it is
Buggyeye Posted June 25, 2016 Posted June 25, 2016 That's quite close to blown gasket temps. You might be lucky though. Some survive some dont
Buggyeye Posted June 25, 2016 Posted June 25, 2016 Now that I think of it. It could be a blocked hose or rad.
Mr B Posted June 26, 2016 Posted June 26, 2016 Use gas analyser to sniff for exhaust gasses at the rad cap port. if passes that, inspect coolant pressure holding/psi-value, inspect thermostat for function, finally fully drain flush & refill coolant & see how temp runs in normal use ...
Dav555 Posted July 2, 2016 Author Posted July 2, 2016 Just wanted to thank people for there replies. Turns out there was a small water leak and car is running to normal temp now 😀
