GM Cooling System Seal Tabs question

Postby rrw2323 [OP] » January 12th 2010, 8:27pm

Hi everybody,

I recently changed both head gaskets on my 2000 Astro/ 4.3 W vin. After the job I treated the cooling system with K&W Nanotechnology Head Gasket & Block Repair just to hedge my bets. The van runs great. Now I recently purchased GM Cooling System Seal Tabs for electrolysis prevention. I haven't added it yet. I was curious on people's take on whether those two products could have a bad reaction with other.(The K&W was completely drained and cured 24 hours)

Welcome to the club. Are the tabs designed for your engine?

I bought the pellets at the dealership. It said it was for all water cooled and aluminum engines.

The GM seal tabs are just crushed walnut shells (nut allergy beware!)...I can't see a reaction hapening.
