Water Pump in an 86 GL

[SyntheticBlinkerFluid]

I just got an '86 GL FWD Coupe and I was planning on picking up a Chiltons manual to give me some help on it. By looking at the engine, it looks rather self-explanitory, and I could probably do it without.

 

My questions are: Is there anything I should worry about when replacing the pump?

 

Does anybody still sell a factory service manual? If so how much.

 

I have not had any luck looking on the net.

 

Thanks.

FSM's still pop up her form time to time for sale. there are links to pdf FSMs around too. chiltons and haynes will get you buy in a pinch. I prefer the Haynes.

If you're going to replace the water pump, you should replace these items too:

 

1. Oil pump main shaft seal
   
2. Front crankshaft seal
   
3. Oil pump gasket
   
4. Timing belts
   
5. Little bent rubber hose at top of water pump
   
6. O-ring at end of tube from rad to water pump
   
7. Camshaft oil seals
   
8. O-rings between cam carriers and head
   
9. Fresh high-temp RTV between cam carriers and heads
   
10. Valve cover bolt washers
    

The reason for the timing belts is that you don't know the state of the ones that are in the engine now. The bent hose and the O-ring are things that can go at any time, and both are a pain to deal with -- especially that dinky hose. The rest of my recommendations just deal with curing any oil leaks that might occur.

The water pump bolts are different lengths,long and puny, and shear very easily. If you are removing the original, or a very old pump, be prepared for disappointment here. Be sure to use NEW bolts with the new pump, and "never seize" or a like product. DO NOT use Loctite! There is a nasty bolt hidden on the lower part of the drivers side of the pump.Treat it with kid gloves as it is prone to shear. The engineer that designed these bolts should have to remove and replace one water pump a week for the rest of his/her life! Good luck!

Thanks for the heads up guys.

One more thing... there is a long and a short type pump.

 

One has studs and one has holes for bolts. I THINK the studs are on the ones with factory AC and the ones with holes for receiving bolts are for those with no AC or dealer (outboard) AC.
