I am looking for the 'best' radiator stop leak on the market to use in my van. By 'best' I mean the most effective with the lowest chance of restricting passages. The side tank seal has a small leak and I need to top off the coolant every week or two with a half-ish gallon. I know the best solution is a new radiator but this van is truly a beater with a heater and spending $100 is something I would rather not do.....
I used Bar's Leaks heavy duty stop leak (black in color with what looks like pellets similar to rabbit food) on a 'gusher' and was shocked how well it worked for almost three years. The only downside is the coolant system became very nasty and the heater core slowly lost its effectiveness. I would rather not use the heavy duty version in my van after completely flushing the cooling system and replacing the heater core a few weeks ago. I am not concerned about the green coolant changing color but am about the cooling system looking like gross black pudding inside and the new heater core loosing effectiveness. This van is 22 years old and has marginal heat to begin with.....
Please post up if you have experience with other versions or other brands of stop leak......
