hi there my head g has blown i was wondering do you have to drop the engine out to get to the manifold bolts or is it possible to this with the engine in any info would be great please thanks. paul :)
-
you can get to everything without dropping the engine to do a HG
It has definately gone I take it? often misdiagnosed...
-
hi there thanks for the help i did a water solution check and it pressuring up and bursting hoses its not overerheating yet or mixing oil and water yet thow :y
-
HBV working? Check that for any leaks :y
-
sorry what does hbv mean :o :y
-
Heater By Pass Valve, its behind the engine block, drivers side. It shunts water into the heater matrix or engine block, depending on your climate setting. These are known to fail, check that for leaks or possibly sucking in air...
HG's on V6 are generally very reliable, has it had regular coolant changes with good 50/50 mix?
-
it had its head gasket done about 20000miles ago i :t had the water changed then. are you saying it might not be the headgasket then :y
-
Ideally coolant change every 2 years/20k. What are all the symptoms you`re experiencing :question
-
Did they reuse the bolts?
Should last a LOT longer than 20,000 miles
-
its bursting pipes its burts my heater matrix aswell and i had a water solution test and it changed colour slightly but isnt overheating and not mixing oil and water in the engine. my heaters didnt seem that warm for quite awhile :y
-
Compression test :question :question
-
i have already started stripping it down the cambelt is off, i dont know if the headbolts were changed they used red sealent everywhere in stead of replacing the seals had to buy rocker gaskets and little rubber rings for rocker cover bolts to stop it leaking oil bloody garages they can never be trusted, it was done on warranty when i first had it :y
-
head gasket only lasted 20k? Its either being seriously abused with pure water coolant, or something was not fitted right. Should be talking 100,000 minimum for a HG
-
its had a good life but i serviced it regulary do you think there is a possibilty that the garage didnt use new head bolts just changed the head gasket they didnt renew any of the other seals because i had to change the rocker gasket recently after and small rubber seals that bolt the rocker covers down :y
-
The garage doesn't fill with confidence from what your saying mate, to do such a big job and then scimp on gaskets thejn load everything with red sealer perhaps taking it back maybe a better option. :(
-
it was a few years ago now but ive only done about 20000miles it would be better for me to do it myself im half way there just got to get to the manifolds off and then i can get the heads of if i do it myself then i know its done right thanks for the info its been really helpfull :y :y
-
It sounds like you're going to attempt to remove the exhaust manifolds from the heads?
I think it's better/easier to disconnect the manifolds from their downpipes and take the heads off with manifolds still attached.
A V6 owner will hopefully confirm shortly. :y
-
your probs right they look like a right pig to get to from the side thanks :y :y :
