First, before you do anything, you'll need to get rid off your Haynes manual. I would not trust anything in it and it will do you more damage. Get your self a BENTLEY MANUAL for your car (E30). It is by far the best you can by for your car repair and runs below $50.00 from good sources.Check e-bay. Mazen 1984 528e 1982 320is Mercedes benz 190e 2.6L previous owner of another 12 BMWs. I'm replacing the water pump on my '84 325e. Referring to the Haynes manual it says I have to remove the timing belt tensioner spring before removing the last bolt holding the pump on. Is this so? Thanks in advance.
