Timing Belt
-
I'm going to do a timing belt, misc belts, and water pump replacement first weekend of October on my 1990 325is.
I should have all the tools necessary, including a 36mm cone wrench for the fan bolt. Any parts I'm missing or anything else I should do while I'm in there? I attached a screenshot of my shopping cart but it's tiny. Here's the list
- Water Pump, Single Outlet (uses metal impeller) NOTE: Also use one 11-51-1-722-677-M17 gasket, 325/e/es/i/is/iC/iX (9/87-92)

I would replace the distributor cap and rotor if you are unsure of the age/condition.
I am wishing I would have replaced my camshaft seal but didn't (just because I would hate for it to start leaking, get on the belt and have it jump a tooth / break prematurely)
You may check into replacing the alternator mount bushing ( I have never done so but was surprised when I saw it marked down as a replacement part on some parts sites)
It would be a good time to replace the coolant hoses up front.
I personally would use RTV on the water pump gasket. The Bentley manual made no mention of it, some techs will say you dont need it, I thoroughly cleaned and prepped all my surfaces and ended up doing the timing belt job all over again the next day because it leaked.
I spent a lot of time cleaning and de-greasing parts since it was when I first got my car. So the whole job took me about 6 hours start to finish working leisurely. But after I had to do it again (due to the leak) I had it all re-done in 2 hours.

I would recommend checking your vacuum lines, especially the one under the intake. The valve cover gasket and oil cap gasket are worth replacing, too.
