How clean for new gasket? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

dma05 · 05-09-2021, 09:53 PM

I’m replacing the water pump and other parts. This is how clean I’ve gotten the surface so far. How clean does it need to be before applying a new gasket? Does all of that black residual need to come off?

If it does, any tips or tricks?

Thanks

I cleaned mine pretty well. Not sure its 100% needed, but i did it. I used a razor blade and a rag with solvent. Go slow and be careful. Most of it will come off.

I use a razor blade as well. very lightly, just enough to get the residue off and make sure it doesn't dig into the block/mounting surface. As gunchamp said, slow and careful.

You need a flat surface to seal against. I would clean it up a bit more with a razor as mentioned. Don't want to have to take it apart again because of a leak.

Plastic razor made specificially for this purpose. Get it clean and not damage the surface. All auto parts stores have them for a couple bucks.

Thank you everyone for your input. I have plastic blades I can use. Not sure why I didn’t think of using them sooner.

Thanks!
