Morning all, I believe Ive got a split hose on the bottom of my expansion tank (only a small split) as its the other halfs car Ive got to do the work and find the problem.
Anyway is there a set procedure to bleeding the cooling system, cos if I have to take off pipes im gonna be dumping coolant which will need to be replaced. And I dont want any air locks like I had on my beloved E30.
Also the heater isnt really pushing out to much heat, any ideas as to why?
Many thanks

jcjdavis1, many thanks, had a nightmare just getting the underside protection off a right krypton factor that was, anyway it turned out it wasnt a split hose but a small leak on the nearside bottom of the radiator, had the fan off and all shrouds etc to make sur nothing else was wrong, so the only thing I could do for now was to wang in some radweld, which has stopped the leak, but I will have to see about getting another radiator just for her piece of mind.Will have to look into changing the filters where abouts are they located in the car?

Hi on the 96 model they are on the bulkhead in the engine bay.There is a good write up in the e36coupe.com but I cannot log in for some reason.It is quite easy,you took a cover off to access the heater motor then both sides of the motor came off to change the filters.I will try and find the write up for you.

Hi This might help. Jim
1. Open the bonnet (overall you'll find it get's in the way slightly but to remove it would be a nightmare)
2. Peel off the rubber stips that go round the engine bay and up round the wiper linkage box.
3. Unscrew the little grey clips that hold down the plastic cover that goes under the windscreen.
4. Remove the wiper arms (makes life tons easier)
5. Remove the grey cover.
Under there in that small space you'll see the blower itself, which resembles a short section of black drain pipe set horizontally and is about 22" in length including the filters.
Each filter is clipped onto either end of the blower and incorporates a plastic cover to stop water going onto the filter.
Remove these, taking a few seconds to marvel at how black and sooty they are (mine resembled 2 lumps of coal) and replace ensuring the covers are on them.
Put everything back together and feel the breeze!
