scoobyfuzzy Posted July 12, 2006 Posted July 12, 2006 ok guys, more advice needed for a mates scoob, its a 93 wrx import, its overheating when sitting idling, temp goes back down a bit when driving it, hes just had the thermostat done thinking that was the problem but its still overheating, top radiator hose is hot but the bottom hose stays cold, when u take the expansion bottle cap off after driving it the water in the expansion bottle is bubbling. and alot of steam coming from the car. any ideas on the problem? also the engine is rocking quite a bit in the engine bay, the garage he took it to says its cos its firing on three cylinders, would this be right? i thot it might just be the engine mounts, but garage said it wasnt. fuzzy
scoobyfuzzy Posted July 12, 2006 Author Posted July 12, 2006 thats wot i thot aswell, but surly that wont be the problem if the garage has done it correctly. think the guy at the garage said it might be some kind of problem with the cylinder head. fuzzy
rabskyline Posted July 12, 2006 Posted July 12, 2006 airlock,fecked water pump,blocked radiator. hard to diagnose without seeing the car !
the squiggle Posted July 12, 2006 Posted July 12, 2006 ........or blockage in the bottom of the coolant system. Does sound like the coolant is not moving round the system A misfire on one cylinder will make the engine rock strangely
scoobyfuzzy Posted July 12, 2006 Author Posted July 12, 2006 saying that, u know the small water pipe that goes from the top off the radiator to the expansion bottle, the water doesnt run consently thru that pipe, which i found strange, it kindy spits n spurts thru the pipe, if u know wot i mean. fuzzy
seafar99 Posted July 12, 2006 Posted July 12, 2006 maybe worth checking the oil filler cap to see if it's showing ' carmeled coloured oil '= cylinder head gasket gubbed. could be your mates radiator has collapsed inside and blocked if 'top hose is hot and bottom hose is cold' or as doug says could be as simple as an air lock.(make sure you refill with the heater in the 'HOT' POSITION.
scoobyfuzzy Posted July 12, 2006 Author Posted July 12, 2006 yeah checked the oil filler cap, its fine, but a horrible smell comes from it, also a horrible smell comes out from the expansion bottle aswell when u take the cap off. fuzzy
seafar99 Posted July 12, 2006 Posted July 12, 2006 maybe worth taking off the top rad hose and the bottom one off then run some water via a hose through the radiator to elliminate the radiator.
scoobyvalet Posted July 12, 2006 Posted July 12, 2006 had one in at work before with similar problem,turned out rad was partialy blocked,tried flushing through with pressure washer and all looked ok but still overheated,fired in new rad then no probs.may not be same prob with you though if engine has got a missfire.
seafar99 Posted July 12, 2006 Posted July 12, 2006 he may well have a missfire but can't see how that would affect his overheating problem, unless it's the water pump?
dougster Posted July 12, 2006 Posted July 12, 2006 Mine ran like a badger on mushrooms until I replaced the plugs. There is a proceedure to clear an air lock but I'd get it wrong if I tried to explain. Someone will post it.
G.T. Posted July 12, 2006 Posted July 12, 2006 bit off the thread sorry fuzzy, but dougster how does a badger on mushrooms run , never heard that saying before let alone seen a badger on mushrooms, would be entertaining watching a badger on mushrooms when you were on mushrooms yourself though i know hee haw about airlocks sorry fuzzy
dougster Posted July 12, 2006 Posted July 12, 2006 Badger and Mushrooms You will agree this does not sound like a healthy flat four......................... Thanks for your attention to detail once again Gareth.
G.T. Posted July 12, 2006 Posted July 12, 2006 pmsl glad my car doesnt sound like that that would get right on your berries after a very short time badger badger badger badger ffs
bigdavie Posted July 12, 2006 Posted July 12, 2006 jeez thats an auld wan !! didnae think it was still doin the rounds !!
oz *sti* Posted July 12, 2006 Posted July 12, 2006 I would say it could be the head gaskets gone mate - I had the same problem just under a year ago [], after I took the car out for a run the coolant would be bubbling away in the expansion tank - these bubbles were hydro carbon gases escaping from the head gasket. Are you losing coolant or is it coming out of the expansion tank after a run? When the heads went on mine I also checked the oil and it was always fine the whole time!!! so be warned checking the oil is not always the best way to check that the heads have gone. Fingers crossed it's not this mate.
ormiboy Posted July 12, 2006 Posted July 12, 2006 mine did this a few months back, in the end it was just a leak from the rad plastic end cap. the water level in the expansion tank did not drop untill i squeezed the top rad pipe. then it would drop to show the real water level. are you sure its not just loosing water? Try squeezing the top rad hose, if you get some nice gargling noises and some bubbles then it would look like a similar problem to mine. new rad was my fix and only £100 notes so noe the end of the world. As for it being the head gasket is there not some funky machine that looks for gas contaminants in the coolant to confirm gasket bother? best of luck. willie
andrew_lally Posted July 12, 2006 Posted July 12, 2006 do a compression test when fitting new plugs as first port of call to cure misfire!!!! this test will show if gasket is starting to fail fuzzy regards andy
scoobyfuzzy Posted July 12, 2006 Author Posted July 12, 2006 right, the guy took the car to another garage, this guy said the car aint misfiring, as for the overheating problem, ma mate cant remember the name of it but says the water was pi$$in out the top of the engine, under the inlet manifold somewhere! wots under the manifold that the water would pi$$ out from? fuzzy
andrew_lally Posted July 13, 2006 Posted July 13, 2006 theres a main water pipe that feeds the circulating water from one head to the other mate...may just be a burst pipe!! gonna be tricky to get in for a look though!! may be easier taking manifold off !!.. 8 bolts just below the injector rails will take this off but still loads o pipes holding it on have fun fuzzy lol regards andy
scoobyfuzzy Posted July 13, 2006 Author Posted July 13, 2006 alrite andy, i aint doin it, its in the garage getting done. lol i was just wondering wot was under the manifold that could be leaking water, lol fuzzy
scoobyfuzzy Posted July 26, 2006 Author Posted July 26, 2006 right guys the latest on this problem, the guy at the garage said it was the head gasket, but no hes not to sure now if it is, thinks it might be something else.. ffs. glad this aint my car. lol but if it is the head gasket, is this a costly repair?. waiting to hear bk from mate for the latest on it. fuzzy
bigdavie Posted July 26, 2006 Posted July 26, 2006 i think its an engine out job mate unfortunately !
road warrior Posted July 26, 2006 Posted July 26, 2006 Im getting my head gasket done on my MY95 classic just now If it is yours dont expect much change out of a grand and a half... and thats assuming the block's OK And yup engine out job Sorry mate... John
