There is bugger all to it......remove the oil filter, drain the coolant, disconnect the two coolant hoses and then there is 4 bolts holding the heat exchanger/oil filter asembly (its all one lump) to the block, remove them and the whole lump comes off...

Clean well and fit with a new gasket......

Are you sure its the oil cooler gone......

Well he has told me that the oil cooler has been bypassed and there was like a white cream gundge in the water. (if I have got that the right way round). He has flushed it out a few times but now has a blockage somewhere I think. Also if the car is left for more than a day it has trouble starting. Left for about 5-7 hours she will start. New glow plugs have been fitted. What could be that problem?

First question, how do I sort that problem out with the Injector bleed off pipes?
Second question Yes the coolant pipes have been disconnected and bypassed.

Thnx MDTM will do that one first when I get the car. Now I take it the bypassed pipes will need to be reconnected once the oil cooler has been fitted (might sound a bit stupid coming from me), is there anything else I must do before fitting the new oil cooler first apart from flushing the system and draining the oil? Also how much will the oil cooler cost?

Try the low foam liquid first as it is a detergent which will break down the oil and Clean the surfaces of the hoses and coolant bottle.the coolant bottle can be the worst part to get clean as you cant get to the compartments inside. Then flush with the forte to get rid or the detergant. Good luck and keep us up to speed on how your doing.

I bought a kit for my Astra from a local motor factor - only a couple of quid. Obviously you'd need another 2 pipes

Could do with a cut-to-size length, as need to redo boost sensor pipe as well...

Are the bleed off pipes these ones?

If not which ones?

If needing more pictures I can take some.

This is the condition of the rad tank!!

This is the pic of the bypass of the oil cooler.

Any comments and help will be appreciated. As you can see the engine has not been kept clean so this is the FIRST thing that gets done before I start on this.
