How To INSTALL a Chevy 350 WATER PUMP

[@roostgarage]

I use DupliColor cast grey engine paint. Looks like bare metal, like your pump and master cylinder and since it’s not clear it won’t discolor. Corvette looks good👍

Thanks!

Great job. Very helpful! I also have a 1976 but it's not as clean and pretty as yours. I'm jealous!

[@76vette]

Thank you! 😊👍🏻

Is one of the pump mounting bolts longer than the others? If so, where does it mount? Also what are the length of the shorter bolts? Thank you!

It’s been a while and I don’t really remember, but this link may help: www.jegs.com/i/JEGS/555/83900/10002/-1?gad_source=1&gbraid=0AAAAAD6OBRGNItqPfwWlD0sOu1d3NZ_BW&gclid=EAIaIQobChMInrHg6aawiQMV9aJaBR1KByx6EAQYBSABEgLU2fD_BwE

Any chance you have a part number for that brass plug you used on the intake manifold that typically routes to the heater core?

[@76vette]

The thread of both the water pump and intake manifold for the heater hoses is half-inch. I bought 1/2-inch hex NPT brass plugs at ACE Hardware and installed them with Teflon tape. Any big box store will also have them. 1/2-inch countersunk plug YN LF 4505350 www.76vette.com/2019/06/heater-core-delete-fix-ac-issues.html?m=1 Thank you for watching! 😊👍🏻

[@zachreese6540]

@@76vette Just out of curiosity. With the difference in metals, did/do you have any concerns regarding using a brass plug into the aluminum intake or for the radiator drain?

[@76vette]

@@zachreese6540 Not really.

I just installed mine and it seems to be leaking. I have to take it off and redo it. Are there three bolts on the alternator side? I only remember pulling two out.

[@76vette]

Two bolts per side for the water pump. I use FelPro gaskets amzn.to/3uqhkTs and thread sealant on all four pump bolts as they’re not blind holes and they can wick coolant. amzn.to/3VzRqbV I also posted an article to 76vette.com with lots of photos which may be helpful. www.76vette.com/2021/01/c3-corvette-install-water-pump.html Good luck. I hope you get it sealed properly. 😊👍🏻

I'm going to replace my 1979 Vette water pump this weekend. Making some bad bearing noise. Did you use grade 8 water pump bolts, and did you have any trouble getting the old bolts out? I know they can have rust issues in that area. Thanks

[@76vette]

Hello William. I am pretty sure I used grade 8 bolts, but grade 5 will work just fine. I did not have any issues removing the old bolts since the pump was replaced when I had the engine rebuilt, and that made things a lot easier. Yes, old bolts can snap, so using lots of penetrating fluid is a good idea. Good luck! 😊👍🏻 www.76vette.com/2021/01/c3-corvette-install-water-pump.html

@@76vette Well I should get the new water pump for the 79 tomorrow. So I took the old one off today. Gave it a good spin when it was out. The thing sounded like a bag of rocks. Can't wait to hear a smooth purrrr under the hood! Nice to see someone as meticulous about their Vette as I. Thanks. PS That bottom radiator hose is a monster!

[@76vette]

@@inell6 Oh yes. Replacing the lower rad hose with the shroud on is the stuff of nightmares.

[@inell6]

@@76vette I think I ordered the exact same pump. AC Delco #252-585. Painting mine black because my motor is black. I like the black and chrome look. Hows it going with your 76, still have it?

[@TimeToBeKind]

I’m buying a water pump, and though there’s plenty of Edelbrock parts on it, I would be insane to spend $300.00 on the edelbrock name, I don’t care how much more flow it gives me. I’m trying to find one that kinda matches the finish. I the Auto Zone’s Duralast Heavy Duty Aluminum might match.

[@76vette]

Hi Tony, I used an ACDelco water pump for my 76. They are cheap and they’re the right part for the car. 😊👍🏻 amzn.to/3BwP8As
