What do I need for replacing a water pump? (Page 2/8)

Also, I accidentally mixed coolant (it had green, put in orange - wasn't paying attention) some time ago. When draining the coolant system, does it need to be flushed in some way?

I would flush the system and refill with old style 50/50 green ethylene glycol /H2O mix. As for the friction on the water pump shaft; that's the result of the tight seal around it. that prevents leaks.

Cliff, I see that your pump didn't come with the clamp. I also noticed that in my link, the image has been removed. Here's an image of a clamp, though it isn't the cheap kind that comes with most water pumps. Our newsletter article has a picture of that one.

Here's the image that's missing in my link:

I read in another post that a C-Clamp would also work?

Also, looking at this photo:



It seems that the timing cover is still held in place by three bolts making me wonder a clamp is necessary at all since it would require a tremendous amount of force bending the timing cover to make it come loose at the top:

I did it once without the clamp because I couldn't figure out how to use it. It worked ok but maybe I was lucky. I've read some people having a bugger of a job getting the pump off and I can see the timing cover seal being broken in those circumstances.
Since then I've always used a clamp of some sort. Had to modify the supplied one (expand the cut out to clear the case)

Anything I might say is probably worth what you paid for it, so treat it accordingly!

You won't be bending the timing cover.
But it doesn't take much to break the seal of the timing cover gasket and create an oil leak.

Yes, V6 WP "bracket thing" above keep pressure on T-cover to save the gasket there. You might not bend the cover you see w/o that or something equiv to it but enough to F'd the casket.

Watch you Don't cut into the Timing cover etc to scrap off gasket(s). Very easy w/ aluminum parts.
Best is use spray Gasket Stripper and wait for that to loosen old casket. Then use Brake cleaner as final wash before new gasket.

Use paint or spray Permatex High Tack or equivalent w/ new gasket. Not RTV Silicone.

Bolt Torque specs, most need Clean Dry holes and bolts. Use a torque wrench w/o that is useless and can even break bolts or strip threads. Anti-seize and thread sealer is lube during install and throw out most torque specs.

When done w/ WP, empty the rest and fill w/ 2 gal equiv w/ pure coolant then add water.
If possible, fix WP, then flush, then refill same method.

Coolant is HAZMAT and regulated waste in most "Western" countries and get big fines catching dumping in sewers etc.

I used the supplied clamp... but if a C-clamp will hold the top of the timing cover tight the whole time you're loosening the pump bolts, removing the pump, and installing the new pump... go for it.

And yes, you install the clamp before you loosen any water pump bolts!

I don't think I can get the clamp here. Not even sure what it would be called in dutch. 🤔
