Hi Dave....
Got your E-male and here I am, Before you remove the staples from your shroud please drill 4 holes (1/4 X 20 threads with nice flat washers) on each side of the shroud....
Those predrilled holes will aid you on the reassembly and will line up the shroud perfectly.....
Now for the pump, Since I'm not sure of your year and engine (REVERSE FLOW) or not here are the phone numbers directly into "Stewart pumps " WWW.Waterpumps.com " 1-906-789-2816 and the Tech line is 1-336-859-2555
We just finished out the new thermostat change out in 110* weather and it wasn't fun BUT both air conditioners were on full blast and the cab area wes cool...

Jim

I wasn't aware of an issue with 454 water pumps. I have a 1999 chassis - what should I be checking for please?

I just finished replacing the water pump on my 1985 Winnego with a 454 engine. The bearings also were also shot. It only took me about three hours to replace it. I had no problem finding the correct water pump. Just glad I found it before it went threw the radiator.

When I replaced mine I didn't remove the shroud. When I removed the fan, I just let it lay in the shroud. There was room on mine to work around it. It took a lot less time then removing the shroud.

I too just replaced the water pump on my '93 Brave with 454. I didn't remove the radiator because I did all the work from the top of the motor inside the coach. Initially took over three hours to replace, then filled radiator with water, started the motor and noticed a leak. Gasket move . Started from square one, replaced gaskets, re-assembled components...done in 30 minutes. BTW while at it, I replaced all the belts and both radiator hoses.

One thing for anyone doing this yourself, bring your existing water pump with you to the parts house because the replacement year for mine was from a '73-'84 GMC that had an extra threaded "boss" that the '93 year model didn't.

It is also good to get some glue to secure the gaskets in place on the water pump. I usually use weatherstrip adhesive, the yellow glue frequently called "gorilla snot". Make sure it is dry before you try to install it.

Glue gasket to the pump!! That way, if you have to ever replace it again, it'll come off with the pump (most of it). Glue it to the block, and you'll be scraping and cursing for hours.

Same for oil pan, tranny pan, head covers, intake, etc...
