Hey guys, recently picked up a Hawkeye 2006 2.5 wrx. been running fine until a few weeks back it overheated and had water coming out from the tank next to radiator (Overflow tank?) it only happened the once so didn't worry too much. read on here a few days back about running the car up to temp the cap off the header tank and this is where I've noticed all this foaming happening. it certainly doesn't look normal an I could only assume the worse but just want confirmation please! also if this is the case, im not far from Norwich and would also need advise on anyone specialize on Subaru's for the job! Cheers

 

doesnt look good, need to get a sniff test done

 

clive atthowe is in norwich and apt in lenwade.

 

looks like there was soap in the coolant? never seen anything like it

 

tbh that's what I thought! had the previous owner mistaken fairy liquid for antifreeze lol!

 

well its always a possibility that he had stored the coolant in a 5L soap bottle ay? perhaps a flush and new coolant would be a good idea

 

Yeah maybe flush the system, may change the thermostat whilst doing it and see how it behaves then... try the cheaper options first lol

 

Just get a sniff test done, don't waste anymore cash till then.

 

Just some extra info, I'm building loads of 2.5's at the moment, what I tend to see is headgasket problems that I belive are caused by the infamous ringland issues, i.e. the pistons start to pass a small amount of oil which can't be compressed. this then lifts the heads and you get the headgasket issues. So the diagnosis is headgasket problems but the cause is ringland issues. Have a look at the plugs and se if 1 or more are a bit oily, and is it using a any oil?

 

Cheers for the advise, will certainly look at the plugs

 

Oh sorry oil levels seem to be ok

 

hhmmm just called clive atthow and apt norwich and niether companys can help I would take it to my local garage but would rather pay the extra to take to a specialist, or am I just as good to take to a local garage? All I'm really looking for is a guide price for either the headgasket to be replaced or even uprated parts (pistons ect) .... whatever is advisable really?

 

headgasket is full rebuild, will more then likley pinched the crank bearings.

not sure whos down your way as far as decent specialists.

any garage should be able to do a simple sniff test though

 

Looks to me like someone has put screen wash in it by mistake. I'd flush it out with a hose pipe and refill with just water and run it for a couple of days getting it up to temp, before going down the rebuild route, that way you'll be able to see any oily deposits.

 

That was might thought to , screenwash , deicer anti freeze easy for an idiot to get confused

 

Yeah I would say so, I took the expansion bottle off the s8de of the rad and it doesn't smell like antifreeze.... more like a screen wash lol!! Think I'll head down the route of replacing the thermostat and also change the coolant, run it for a couple of weeks then sniff test for peace of mind

 

At least the inside will be clean

 

Haha true!

 

why spend the money then sniff test? just get the sniff test done, driving it if the HG has gone will only damage it further
