A question for those who have replaced the water pump

I have a good sized job coming up, new trailing arms, new parking brake shoes, rebuild or re lube and install new boots on the CV joints and new wheel bearings on the rear.....also in that lineup is a new Motor Mount...I have everything sitting in my garage and I was pondering the question. Is it a lot easier to replace the water pump once you have the motor mount off ?

My water pump is not giving me any problems, no noise, no leaks nada....but my Bavarian Beauty just turned over 70 K miles and well...should I or wait for problems ??

Thanks

Dwight

It makes no difference if the motor mount is on or off
You write "my Bavarian Beauty" did you accidentally buy a BMW and think it's a Porsche? Porsches are not from Bavaria. Hint: if the engine is up front it's actually a BMW ;-)

Yes a Typo

I do have a E36 with 147K on the Odo and it is one of the best cars ....if not the best car I have ever owned

PS I appreciate the info on the water pump.

I replaced my water pump, thermostat, and front motor mount. check out Pedro's diy. Once you take out the motor mount the water pump is a breeze. I removed the engine cover inside the car and got it up on jackstands to get underneath.

It is much easier to replace the WP with the motor mount removed. You can get a torque wrench on every WP fastener.

Nice baiting in the thread Timco.

I understand that taking the water hoses off to drain the coolant makes it easier to drop the front engine mount during removal of the mount. Being able to torque all of the water pump bolts is something I did not know could be accomplished with the motor mount out of the way.

Just stuff I find online. There's great ones.

Torque wrench is nice, but not necessary. I just snugged the water pump bolts up, and gave them another quarter turn.
The vacuum fill tool held 25" of vacuum for a half hour, so I surmised I was leak free.

I'd hold off on the pump as you have no symptoms and your upcoming tasks are not related to the WP so there is no "while I'm there" cost or time savings.

and I just replaced my WP at 119K miles due to a small drip. After getting to the pump, I just saw a small drip from a lower bolt. Since I was in that far and had the part on hand, I went ahead and replaced the WP and thermostat. After removing and inspecting the (original) pump, I noted no bearing play or wear to the pump veins

Given small torque spec for the WP (12-14 Ft-lbs) I'm fairly certain that I could have re-torqued the bolts a and been good to go. Looking back, I should have tried it.

I even kept the old pump!

I found that a 10mm deep well socket with 1/4" drive will be your friend when replacing the water pump.

I did both a few months ago. I don't think it would have made that much difference.
