Mikeparkyn11 Posted September 28, 2015 Share Posted September 28, 2015 Hi all... I have an 07 WRX Ej25 My car has started over heating. My reservoir keeps refilling unroll engine has cooled down. Going back about 3 weeks ago I had the rad pipe burst. I had that changed when I cot my clutch done, worked fine for couple of days then over heating again. Changed the thermostat and again worked fine for about 4 days then over heating again. I have drained all the coolant out and replaced with more... seems to be idling ok at the moment. I inspected the heads couldn't see any noticeable signs of leakage, and can't smell the eggy smell or see and white gunk. So at the moment I'm very puzzled please anyone share a little advice. Thanks Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted September 28, 2015 Share Posted September 28, 2015 Do you have any bubbles in the overflow/top up bottle? Also try to get a sniff test done of the coolant as that will pick up if the exhaust is leaking into the coolant. Quote Link to comment Share on other sites More sharing options...
Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 Yeah there was a bit of bubbling going on, I just won't wanna drive it to a garage to get snif done if it's going to damage driving Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted September 28, 2015 Share Posted September 28, 2015 You can Google "car sniff test" and it will bring up shopping options if you wanted to do it yourself without driving the car. Failing that ask the garage if at all possible someone can come out. If you have aa/rac cover even better. If you have bubbling id certainly recommend a sniff test. Even stick your nose in the overflow and check for exhaust smell. Quote Link to comment Share on other sites More sharing options...
Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 I did poke my nose in but all smelt pretty normal, I will have a look on Google now thanks Quote Link to comment Share on other sites More sharing options...
Tidgy Posted September 28, 2015 Share Posted September 28, 2015 sniff test isn;t just stickign your hooter in teh cap lol all mikey taking aside, sniff test uses a chemical to test for exhaust gases in the coolant. First thing i would check in the circumstances. Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted September 28, 2015 Share Posted September 28, 2015 I was using the nose method as an extra. If it's that bad even his nose will pick it up. I should have clarified but I was under the impression Mike knew what a sniff test was. Quote Link to comment Share on other sites More sharing options...
Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 I do know what a sniff test is, but of cause still worth having a general sniff. All I can smell is coolant 2 Quote Link to comment Share on other sites More sharing options...
Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 What else would cause over heating? My friend coming later with sniff test the blue fluid Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted September 28, 2015 Share Posted September 28, 2015 Faulty coolant sensor. Water leak. Cooling fan not working. But if it's been overheating and ran hot for a while the damage and cause of overheating may have changed. Quote Link to comment Share on other sites More sharing options...
Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 The fan kicks in when the car reaches correct temp (going by gauge) buy coolant sensor hadn't even though about it. I'm going to try drive it to the Scooby specialist garage nearby that done my clutch to see if they can help tomorrow this is.

Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 Also haven't seen a water leak and I've been.under it about 3 times now don't seem to have any leak. And edge of gaskets seem to look alright as well Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted September 28, 2015 Share Posted September 28, 2015 If you have coolant in it(not just water) you may not see fluid but it should stain pink. Quote Link to comment Share on other sites More sharing options...
Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 I have roughly 50/50 and there's definitely no pink stains Quote Link to comment Share on other sites More sharing options...
stants Posted September 28, 2015 Share Posted September 28, 2015 Could be an airlock ? Are both hoses getting hot after the fans kick in ? Quote Link to comment Share on other sites More sharing options...
Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 I have burped it a few times now, top hose gets hot then fan kicks in and it cools of a bit haven't checked bottom one other then for leaks. I bumped it starting car with cap off letting bubbles all stop then top up with water same process and then putting cap back on Quote Link to comment Share on other sites More sharing options...
WideSam Posted September 28, 2015 Share Posted September 28, 2015 Does it overheat after it reaches normal operating temperature? The water pump might be worth a check... Quote Link to comment Share on other sites More sharing options...
Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 It fluctuates between normal temp and just under the red. I have just been on a 10mile drive no problem and temp was as it should be with no faults no over heating... So puzzled by this Quote Link to comment Share on other sites More sharing options...
Tidgy Posted September 28, 2015 Share Posted September 28, 2015 was it a steady drive or did you give it some hammer? sounds daft but if the gasket is gone near the turbo it will only be on boost it leaks 1 Quote Link to comment Share on other sites More sharing options...

Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 I was giving it some welly about 2weeks ago and the top rad pipe burst and then over heated I had that replaced and I changed thermostat last Thursday and done coolant Quote Link to comment Share on other sites More sharing options...

Mikeparkyn11 Posted September 28, 2015 Author Share Posted September 28, 2015 That's a little risky I feel though... dont want to be stranded or cause more damage Quote Link to comment Share on other sites More sharing options...
