Bars Leak is like a miracle in a bottle. On my 190D with a failing head gasket and cracked head, I was consuming about a quart an hour of coolant. I put in a bottle of Bars Leak, and within 10 seconds the coolant consumption stopped completely. It was amazing. I drove that way for over a month, it was cold weather that did me in when I drained some of the water and added antifreeze but not before my cooling system got kinda slushy and cracked my heater core... when that happened I drained it again to replace the heater core and the leak came back. That's when I bit the bullet and pulled the head.

Last week my girlfriend's Toyota blew its head gasket. BAD smoke, running on 2 or 3 cylinders. I had to drive it 10 miles to my shop. I put in a bottle of Bars Leak... within one mile the smoke stopped completely. Within 5 miles the engine was running like nothing was wrong.

Highly recommended!
