I'm not too clear on this bars leak stuff. In the tech threads it says to add 6 tablets or 2 bottles of powder gold seal, but all of the threads on here say what a horrible product bars leak is. Is that just the liquid everyone doesn't like? Can some one clear this up for me?
Bar's Leaks products are not "horrible". In some cases and situations they may buy you some time before major repairs can be accomplished.
The tablets or powder (HDC or G12BP) were used by GM on assembly lines to prevent early nuisance weeps. The entire idea was scrapped in the early 2000s - 2004, maybe.
If your cooling system has no weeps now, there's no sense in using the stuff. If the system has
obvious leaks, the ONLY proper way to repair - and opposed to Band Aid - the problem is to........... repair it.
GM has issued specific TSBs on this, and goes on to state that continued use of the product when unwarranted can lead to coolant passage clogging, sludge formation in the surge tank and coolant discoloration.
As a matter of record, I do not recommend ANY sort of magic goop, EVER, for a cooling system - - keep it clean and repair it properly. That's called preventive maintenance; Magic potions are not .............
