Water pump gasket spray sealant?
#21
Job complete. I replaced the water pump ( ended up using a gasket from the Land Rover dealer. Replaced all hoses, 180 t-stat. Running temp now 185-188 down from 215. Only casualty was nipple on bottom of reservoir tank. Brass nipple drilled and screwed with red permatex until I order a new reservoir. So far no leaks. I used a razor blade on hand scraper. No way in hell anything less would clear old gasket. It was really really baked on there. Not sure why the scanner lit up a warning, did that on first crank start up after replacing coolant.

Now that we've completely exhausted the topic of gaskets I guess it's time to move on to mating surfaces. I'M NO EXPERT ON THIS and I've probably used tools I should not have, but those whose opinions I respect (e.g. P.T. Schram) are adamant about not using metal scrapers or even Scotch-Brite pads on DII aluminum surfaces. Too big a risk of scratching and causing leaks. It's more work perhaps but an old credit card is my choice. And maybe some chemical solvent for the tough spots.
I WELCOME other (informed) opinions.

Special purpose gasket removers tend to consist of dichloromethane, the same stuff in paint stripper. It is effective, but just horribly nasty stuff, and using it isn't like waving a magic wand. I am simply not willing to use it.
I will use Perchloroethylene -- the chlorinated brake parts cleaner. This stuff is more effective on tough residue than the "non-chlorinated" solvents (which I also use).
A heat gun also works good to remove gaskets without damaging sealing surfaces.
I write it one more time. I greatly prefer o-rings to flat gaskets for water pumps, oil pans, valve covers, and thermostat housings. Flat gaskets are for heads, and exhaust manifolds (I'm not sure there's only one answer for intake manifolds).

Depending on your point of view on the age-old throttle body heater debate you can also just plug the reservoir nipple hole with an appropriately-sized screw wrapped with Teflon plumbers' tape. The line feeds only the TBH. That's how I addressed mine when the nipple broke off mine a couple of years ago. I did eventually buy a new reservoir off eBay but I'm convinced that the plugged reservoir would have worked just fine indefinitely.

another is rounding the edges, as with scotchbrite pads, steel wool, or emery paper, due to uneven application of pressure

If a leaks should appear after all our expert procedures we can always depend on a can of snake sealant.

Slap one of these on any vehicle and it'll be good for years n years lol.

So in the end, I found out how to feel "less robbed" by the dealer. Went to pick up the short radiator hose from radiator to t-stat. Forgot to order it. Picked it up, how much? $65! Auto Zone and O'Reilly had nada. Ok, let's talk gasket while I am there. Looked more solid than my paper gasket. How much? $25!
Ended up buying both, find a NAPA on the way home. Got the hose for $7. Dealer hose going back. Kept the $25 gasket, even though it was robbery- just not as much as the $65 hose. The price of needing parts asap.
