Will this stuff damage the water pump?
Do people use it?

 

[Lightners]

No, ive never seen it hurt a pump and yes it is used. Probably a better question is what are you trying to seal?

I used it once with no luck. But have had good luck with alumaseal.

 

[ts racer]

we used it with alum head and block just in case.
Our pump ran slow with it in system. I drained the water from radiator and it had a lot of small pieces left in water.

I use the GM tablets as insurance in mine. They work well and don't cost much.

I have used Bars Leak in the past, depending on how bad the leak is, it works pretty well. Never seen it effect the pump. We had a small split in a cylinder wall on an alcohol sprinter engine a long time ago. Put some in just hoping to make the night, ended up finishing the season with it before we pulled it out and sleeved it.

GM tablets worked for me.

Old school radiator seal = 1 can BLACK PEPPER

Old school radiator seal = 1 can BLACK PEPPER

I've heard that but never tried it. So it really works?

I believe your suposed to put a couple eggs in with the pepper..no joke..I work in a radiator shop,and the old guy that trained me 20 years ago told me about that trick..I have also heard of putting oatmeal in the radiator..BUT,I have pulled the tanks off of radiators before,and the inlet tanks that had bars leak in them were full of the pellets that didnt dissolve..possible that the people didnt drive it long enough after dumping it in..

Bars has a product now that is like pepper, I have used it with success in late model cars to seal intake leaks on the composite o ring type gaskets.

I always added the stuff cold and before a 50+ mile ride - dont forget to cycle the heat valve to do the whole system.

It works great! In a pinch, (no pun intended) it will get you on the road and where you need to be to get it repaired correctly.

I was under the assumption that we were NOT talking about the old pellet type (maybe wrong though). The pellets suck. The newer "pepper" type stuff works well.

 

[Chuck u Farley M.D.]

Egg whites actually work. My granddad did it all the time on the farm.

 

[DCarr]

Pepper will indeed work.

The GM Tablets are only good for a few months per instructions on the package. The assembly plants put 1-2 tablets in every new vehicle.

K & W Block seal is the best stuff I have ever used ( same as Moroso's Ceramic Seal ? ) PIA to use but the stuff works great !
