About a week ago, my wife mentioned that the heat was not working in our ’06 Equinox. (no overheating & no white smoke). I took it to 2 mechanics, one mentioned a clogged heater core, another mechanic is thinking head gasket.

When I got back, I reversed flushed the entire system with Blue Devil Flush. Might’ve flushed it too good, car is definitely showing signs of a blown head gasket now: white smoke & overheating after driving 30mins. I’m eventually going to replace the head gasket when the weather gets better in IL.

We probably drive 15-20 miles/day. Can I temporarily get by till March/April by using one of the head gasket sealers?

Has anyone used and/or recommend:
+ BlueDevil Head Gasket Sealer
+ BlueDevil Pour-N-Go Head Gasket Sealer
+ Bar's Leaks Head Seal Blown Head Gasket Repair

Thanks!

It’s easy to disconnect hoses at transition from hose to steel line near plenum. You don’t have to unhook them at firewall. Then you can flush out the core with ease. But your overheating problem was worse after flushing so perhaps the head gasket finally let go? If you use sealer now, you might have issue in future with plugging the heater core. So you will have to fix head gasket and unclog heater core.
