I'm ready to put my water pump housing back on the engine with a new gasket. Does anyone have any tips on this? Should I also use a sealant or something?
 
Permatex Aviation. Dark brown, gooey, sticky - apply it liberally to both sides of the gasket, let it tack for half an hour and seal'er up.

I just did mine recently and I used Permatex Hylomar Gasket dressing and Flange sealant. No leaks so far. Knockin on some wood /ubbthreads/images/graemlins/cool.gif
 
Great. Can you get it at an autop parts store, like Pep Boys, Advance Auto, or AutoZone?
 
I've been using Hylomar almost exclusively lately, a little more money but absolutely fantastic stuff. Unfortunately I can't find it anywhere around me but Pepboys. Pretty easy install, gasket, three bolts, done deal. Just make sure you remember to put the water transfer pipe back into it's fitting on the back of the housing before you button it up, otherwise you'll just need to loosen the bolts again to get the play you need to slip that in. You could just remove the bolt from the little bracket on the other end that mounts to the tranny, but I find thats a pain with the carbs and linkage in place.
 
As I stated in a previous post, I really don't care for Hylomar for things such as waster pumps, housings, etc. Many people swear by it. I have it sealing up my tranny (still leaks). Hylomar never really gels, it always stays soft and liquidy. Permatex Aviation is great for areas that have less than perfect fits, such as water pumps with their paper gaskets and oil pans that never quite seal up. Each to his own. An old grease monkey turned me on to Aviation and I have used it for years with success. Hylomar is also getting more difficult to find.

Bill what you say about Hylomar is true, thats why I've found it works best when using a really thin coating. I usually put some on the tip of my finger and just spread a very thin even coat over the entire gasket surface. I've used the aviation sealer also, that is also an excellent product. I don't think you could go wrong with either. If something has a really uneven or pitted surface to it where the Hylomar or something like it wouldn't work then I usually go to a high temp RTV, like Permatex ultra black.
 
I have used Permatex Form A Gasket No 2 for 25 years and absolutely love it for paper and cork gaskets. I have found that since it has a thick consistency it is easier to apply than the thin brown gasket dressing and it also never hardens which makes a good seal on those irregular surfaces. It is also very tacky and holds the gasket in place until you can tighten everything up.
Just thought I’d toss in my 2 cents. /ubbthreads/images/graemlins/thumbsup.gif
 
Before you bolt it back up you might want to look/feel inside the housing to see if 2 of the 3 studs project into the volute area. If you take the 15 minutes to extract & cut them off so the end is almost flush the pump capacity will be increased.
 
Stupid question...if you use the gasket sealants you all are talking about, do you use the actual gasket that I got from TRF?
 
Yes. IMO the only sealer that you can use without a paper or cork gasket is RTV. Hylomar, Aviation sealer, any of those types of things you use them with the solid gasket. I actually use the gasket with RTV also, although it is rated as a "form-a-gasket" I'm usually not comfortable in relying on it alone. If it's a case where I don't have a ready made purchased gasket I'll cut on from a sheet of material before I'll go with RTV by itself. Just my own quirk.
