What is you guys' oppinion on Bar's Leaks products?

DON'T DO IT!

That stuff attaches it's self to EVERYTHING!
Including head gasket water holes and steam holes, water pump impellers, blocking off radiator capillaries, gumming up thermostats and sending units, ect.

Ditto. DITTO. No. Don't use it! IMHP....there are only one or two automotive additives that work, and that means they are woth the money. The rest are, uhhh, SNAKE OIL. Fix the problem the right way, recored, then keep a 50/50 mix of antifreeze/water in there. Really the only additive I like is a product called Rislone oil additive. An old name. Seems to help older high mileage engines, lifter noise, oil consumption.

The water pump shaft seal was leaking on my old, 250k mile Volvo 740. I used a system sealant in it - a silver powder but I don't remember the name - and it stopped the leak and caused no problems for another few months and 25k miles until I replaced the car. Used it only because the car was going anyway.

BTW the [img]/ubbthreads/images/graemlins/codger.gif[/img] trick is to put oatmeal in the system while cold. When the engine starts the oatmeal moves around and some sticks in the leak. Then it swells as the system heats up and cooks it. It worked years ago when systems were unpressurized and probably had larger passages.

And then there's sawdust in the transmission. [img]/ubbthreads/images/graemlins/grin.gif[/img]

That would be Alumaseal, comes in little blue and gray tubes. Stuff is great for small leaks. I carry a tube in my tool box. Have been using it off and on since the 60's on various cars. Coarse ground black pepper is another good temp fix, pepper does not dissolve in water. [img]/ubbthreads/images/graemlins/grin.gif[/img]

Yeah, Alumaseal - that's the ticket!

IMHO... isolate why there is a loss of coolant and fix the cause. You'll be money ahead in the long run.

On Myth Buster's last week they tested placing one egg in the radiator to fix a leak. It stopped the single hole leak in their radiator. In theory, I guess it's similar to the oatmeal trick. I couldn't believe it.

I like bars leak. been using it for over twenty years. In fact all of the major three automakers come from the factory with bars leak. I have never had a promblem. In fact the bars leak power steering condition, solve my squeeking pump.
