Quiet_Hollow Posted June 26, 2016 Share Posted June 26, 2016 Pump came with a paper type gasket. You'll need to take a look at the flange of the replacement pump. The factory pump (AISIN) has a molded channel that's designed to accept a continuous bead of Toyota's FIPG sealant. A very reliable combination. A few aftermarket pumps are machined flat, and use a gasket instead. If the replacement pump flange has a channel, then ditch the gasket, order the correct sealant and proceed. If not, then it all depends on the quality of the surface finish with the old pump removed. Mirror finishes can work with just a fiber gasket. Any defect though, and you'll have to hedge your luck with a good non-setting joint compound in addition to the gasket.....for which I'd highly recommend Hylomar. 1 Quote Link to comment Share on other sites More sharing options...
Karsoncookie Posted June 26, 2016 Share Posted June 26, 2016 I have heard Vaseline is also a great indespensible followup after spicy Mexican food. Just what I have heard, of course. Lars Quote Link to comment Share on other sites More sharing options...
Ceptorman Posted June 26, 2016 Share Posted June 26, 2016 I'm with you on the American made engines (Chevy & Olds) This thing is a bugger to reach too. Nothing like the 455 my Olds 442 had. Just curious….what year 442? My older brothers were 442 guys, they had a couple 65 models and a 66. I had a 1969….cool cars. Quote Link to comment Share on other sites More sharing options...
JJkizak Posted June 26, 2016 Share Posted June 26, 2016 And don't substitute the factory bolts as they are designed for the proper torque within 1 foot pound. And they mean it. JJK Quote Link to comment Share on other sites More sharing options...

jason str Posted June 26, 2016 Share Posted June 26, 2016 Compressing RTV sealant can actually push your paper gasket out of line with your mating surfaces causing it to leak, avoid using a bunch of it on both sides. Yellow gasket adhesive (gorilla snot) to adhere the paper gasket to the pump, allow to dry for a bit bit not cure and you can use a thin layer of RTV on the outside but it is not necessary. I avoid RTV unless i need it on something like a warped valve cover that is no longer flat and even then i use the above method with Yellow adhesive. 1 Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted June 26, 2016 Share Posted June 26, 2016 Shameless plug for a local company. Can't really vouch for the sealer but the tool does indeed work! http://www.valco-cp.com/Tube%20Grip%20Dispenser.htm Quote Link to comment Share on other sites More sharing options...
Don Richard Posted June 26, 2016 Share Posted June 26, 2016 Use Yamabond, a product used on Yamaha motorcycle engines. It leaves a thin coating, easy to disassemble. https://www.shopyamaha.com/yamalube-products/adhesives?ls=yamalube&taxo_productdepartment_ss_facet=36&taxo_productcategory_ss_facet=111 Quote Link to comment Share on other sites More sharing options...
ratcobob Posted June 26, 2016 Share Posted June 26, 2016 While you're there check the alternator too. Have a friend w/ an 05 and the pump and alt went at the same time, seems like was about 110K miles. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted June 26, 2016 Share Posted June 26, 2016 Yellow gasket adhesive (gorilla snot) to adhere the paper gasket to the pump, allow to dry for a bit bit not cure Yellow or black weatherstrip (normally 3M) adhesive is what I always use on paper gaskets. Have been for decades and never had a problem. I'd never use RTV. Quote Link to comment Share on other sites More sharing options...

Have been for decades and never had a problem. I'd never use RTV. That's the stuff, not really a great weatherstrip adhesive but perfect for keeping gaskets in place. GM actually used RTV in place of gaskets for a while, did not hold up well long term. RTV has its uses in many applications but a water pump gasket it is absolutely not needed.

MookieStl Posted June 28, 2016 Share Posted June 28, 2016 ust curious….what year 442? My older brothers were 442 guys, they had a couple 65 models and a 66. I had a 1969….cool cars. 71 convertible with Hurst 3 speed. Kevin Harmon has (if I recall correctly) a 72. Back when I was a lot younger and much cooler, I had two 72 Cutlass'. A hard top and a convertible!! Neither were 442s (I wasn't quite THAT cool). After many years, I could rebuild a QuadraJet in an hour. Through the course of time and raising four kids, they both are gone. Now I'm sad...... Quote Link to comment Share on other sites More sharing options...
JL Sargent Posted July 3, 2016 Share Posted July 3, 2016 Get the pump to block mating surfaces good and clean. Take your time on cleaning those surfaces. That's the main thing. If new gasket is installed correctly, you shouldn't need any kind of sealant. If a gasket won't stay in play long enough to get pump on, I like a product called "High Tack" applied to the gasket before installing. This always does the trick for me. I've installed many pumps and thermostats over the years without a problem. Quote Link to comment Share on other sites More sharing options...
