Did u refill coolant with the prestone and not dexcool? Ive considered getting rid of my dexcool and running prestone extended life antifreeze.

I do not plan to ever return to dealer for warranty work anyways. Just was never crazy about the dexcool in the late 90s-early 2000s. My 4.3 went over 200k miles without dexcool for over 100k miles. Also have a 05' 4.2 vortec that im running prestone green extended life with over 160k miles and no cooling issues.

What antifreeze did you end up using?

Just decided to do my water pump myself instead of having to deal with the dealership. Only thing I'm missing on is the torque for the pulley bolts and the bolts that hold the engine bracket to the block. Can anyone fill me in on this info?
The only issue or problem I had was the return hose from the heater core to the water pump ripped near the water pump nipple when I removed it. Local dealer had one in stock luckily for $25.
Thanks to the OP for this write up.

So you did have to deal with the Dealership in the end, you are out at least $25 and still don't have it fixed right?

No dealing part was ready for pick up when I arrived. It was a simple fix.

I do not have torque info but all pump retaining bolts are to be replaced since they are torque to yield. I am aware that there are different INCH pound specs for each fastener and you must use a degree reading torque wrench (to get the yield spec.)

Reuse of bolts or incorrect TTY will guarantee a subsequent failure.

Well guess I'm in for trouble. I did not use new pump bolts as I must have missed that part or it is not mentioned until now. If so is there a part # for the pump bolts? Do they come as a set?

How much did the Pump cost. Looking back I would have just taken it in if you are below the 125,000 miles or whatever special coverage comes with that part? I had an Engine rebuilt with used bolts under warranty. 2 weeks later it was back in the shop getting a Boltectomy~

Pump with gasket was $55 with a $5 coupon and 20% off offer this weekend from Advance Auto.

The boltectomy wasn't water pump specific was it? Was there a specific problem you had with the rebuild?

The savings on pump covered the new return hose from the dealer. It was so nice bypassing the service dept. And walking out with part in hand. Rude cashier said that doesn't look like a easy job when she seen the part and I said well maybe not for your techs .

Doesn't seem these bolts are readily available. Didn't see them on any gm parts sites either. Does anyone know where to get these bolts?

 

[AutumnCruzeRS]

Held engine up with block of wood and floor jack on oil pan since it was my only option.

Will keep updates with how the reused bolts work out. I drive 100 miles daily for work so if issues are to arise it will be sooner than later. Im at 95k miles now with the first issue with the water pump.

Well put on 500 miles in 80+ degrees and not a single change in level of coolant in reservoir. No visible leaks or smelling of coolant either. Temp gauge stays right at the 198-210 range which is normal with the select-a-tune from trifecta.

This is what hose I believe you're looking for
