Timing Belt / Water Pump DIY - Step by Step Pictures

[unicorn]

Nice write-up . I did my water pump back in the day with the hood attached to the car, in my mom's driveway in a well-heeled residential Philadelphia suburb.
Everyone should change-out a water pump. Such a priveledge. "Bravo"

This post combined with the Bentley and about 20 calls to my father in law was very helpful in tackling my timing belt replacement over the weekend. Many thanks to the OP for taking the time to put it together.

+1 vote to make this a sticky.

In addition to the RTV, I would also suggest adding a radiator chemical flush to the list if you're planning to do one. Using your old pump and T-stat for this job is better than using your new one since crap may get dislodged from your 20 year old cooling system and clog one or both of them.

I've been using your guide over this past weekend. One suggestion is undoing the bolts on the timing belt tensioner. I was having a hell of a time trying to release the tension so i could remove the timing belt. So undoing the bolts immediately releases the tension.

Other than that it has been handy.

Use the blue Hylomar sealant. Pricier, but way mo' betta.

Also, when you bleed the coolant, jack up the car from front left side framerail so the overflow tank is at the highest point. It will bleed faster and easier.

Very nice DIY with great photos Greg.

Great Advice. I actually just did a head gasket on my vert yesterday (check out my time lapse in the OT section of this forum!) and was having trouble taking the bleeder screw out to bleed the coolant, I'll try this when I get home. Thanks for the tip

Another note, if your new water pump uses a basic paper gasket put soem RTV on there to avoid leaks

Also some earlier cars will have small torx hoding on the ignition rotor, not allen


nice write up!

nice write up, seems like you took out way more than i had too. then again i have an eta and it was every straight forward . Take off hood, drain coolant, take off the fan/clucth, remove all coolant hoses, remove dizzy , loosin alt belt take off water pump pully , then take the timing cover and etc etc... But like i said i did mine on a eta not an b25

Sticky this now.

Thanks, going to do this at the before summer after I get the rest of the drivetrain in working order. It's going to be my first non routine maintenance job. New thermostat should be added to master list.

we just did this, and everything is covered here.

However, I'd also like to recommend using a gasket sealant to glue the gasket to either the pump or the block first. There was much wriggling and struggling to get it to seat properly while keeping the tensioner pin aligned, and thus we mangled the water pump gasket and now it leaks like a whore.

The rest of it was not particularly bothersome, although make sure to reference proper bleeding procedures also before going on an extended drive more than 5 blocks from your house/workspace.

also, nice kegerator.

Thanks, yeah, we didn't have too much trouble getting it on there, but I could see how it could prove problematic. I had to cut some details out because I was over the 10,000 character limit, but I think it is a somewhat comprehensive guide, and should get people on the right track. I'm hearing good things so far, we'll see if it actually helps when someone sits down and does it. :D

Very impressed by your pictures. Top notch job. Hats off to you.
