I have an 85 notch back with an 87 2.8 sitting in it ready to hook up. I have found that the water pump doesn't have the aft hook up for that hose. I ordered an 85 pump since they don't cost much, and to make sure it had metal impellers. Are there any more differences on hook up of the 87 engine to 85 car? I have been delayed because of the weather so I am sitting here just thinking about it.

As far as I know the on;y difference was how the heater hoses flowed on 87-88. Makes sense the pump was different, should be fine, might need the older style hoses though...

This process has taught me some things. One is how many tools I did not have. The other is how much I did not know about mechanic work. I am not looking forward to doing the water pump after reading about it on here. I did reach down and get the top bolt out with my fingers. It was that loose. Maybe I will get lucky.

The heater core return hose on the 85-86 V-6 attaches to a fitting on the water pump housing. The 87-88 returns to the passenger side undercar cooling tube. The new pump will need the correct fitting installed from the 85-86 V-6.

Doing the pump is intimidating but not bad at all, I've done 3 in car. Best time is around 15 mins, takes longest to clean the surface. Remember to keep the bolts in order, bunch of different sizes and lengths... Carefully with the two that go through the timing cover. Can strip em, they will leak.

Thanks for the help. I got the new water pump. It came with a small pipe to insert in the pump so I think I am ok. Now I just need to wait on the weather to improve. We are totally iced in here in north west tn.
