Install New Water Pump - A Few Easy Questions
My new water pump should arrive Monday and I want to be ready.
This is for a 78 Tran Am with a Pontiac 400 and an 11 bolt water pump. Thanks for your help, TacoTownCharlie |

Water Pump to Timing Cover Torque 10 lb/ft in 5 lb/ft increments.
Alternate/spiral pattern to even out the fastening. I don't think a sealant is necessary, it can go on dry. JMO.

i would suggest using a sealer on the gaskets, have had water pumps leak over time when installed dry. permatex untra grey or ultra black is good stuff, just use a small amount & thin with your finger, then follow instructions on the tube for install & cure times. after a couple heat cycles its a good idea to go back & re torque the bolts. the check them again after a couple months.
also be sure to clearance the divider plate to the pump impeller for best cooling, there should be some write ups on here or other forums, but basicallly get the plate as close to teh impeller as possible without touching, like .010 clearance. you can tap it with a rubber mallet or hammer carefully if it needs some tweaking. |

Thanks 78W72. The new water pump instructions suggested Permatex #22017 so I'll pick that up. I'll remember to re-check the bolts as you suggest. I have my rubber mallet ready to go, I just need to get a feel for what amount of force it takes to bring the plate closer. Right now it is between .075 and .100 (with the gasket in place) so I don't have far to go. I'll try to post some old pump vs new pump pictures.
I've picked up a spray can of Chrysler Green (Duplicolor DE1619); I want to see if it will blend in with the rest of the engine. The engine was recently rebuilt so I'll keep my fingers crossed that I picked the same color as the rebuilder. Thanks for your help. TacoTownCharlie |

I use High Tack or Gaska-cinch, I'm not a fan of putting any RTV on there, just makes a mess.
See if the insert rubber rings are good, replace if so. If you remove the sleeves, I use a little coat of anti-seize on them so they don't 'stick' in the cover. I've held the plate on the pump, and with slow force, banged it on the garage floor to close the gap, works pretty good, and does it evenly. You can use a piece of wood, but beating on the side of the plate rams the pump shaft, and could impact the bearing/seal. .
