I have a leaking head gasket on my 2000 subaru outback (225,000 miles) I am considering using a Bar's product to repair. The "Fix" product can be used without draining the coolant, the Bar's "Repair" requires a drain and flush. The question is, is there any difference in the efficacy or reliability of the repair in the two products? I don't want to have to drain the system if I don't have to, but I want the best chance of success.

There are pros and cons to both product versions.
The “Repair” product is less expensive and actually stronger on larger leaks. But the disadvantage is you remove all the product from the cooling system so that if a leak opens back up or starts in another area, there is no material in the system to seal it.
The benefit of the “Fix” is that it stays in the system and even though it won’t stop as large a leak as the “Repair” (we are talking close, 2 to 4% of vehicles fall into this category), it will stay in the system and be able to reseal existing leaks or other leaks within reason.
Our new Head Gasket & Cooling Sealant is the best of all of them with the strongest available formula and that it stays in the system. You might want to consider that one too.
Hope this helps!
