If you don't have a blown head gasket and you put bars leaks in the radiator and run it through the engine will it mess your engine up?

Good evening,

Bars leak does absolutely nothing for the blown head gasket. The issue is this sealer actually clogs up the radiator and heater core for circulation.

I would have the system acid flushed to get rid of all that stuff.

Did you have it confirmed about the head gasket?

In theory it shouldn't, however I have seen it plug radiators and heater cores so they no longer work properly.
