Why you should NEVER use mechanic in a can AKA cooling system stop leak

[kywhitelightning]

This is a Nissan 2.5 that had 2 bottles of stop leak poured into it.

The radiator was completely stopped up and 4 of the 6 coolant ports through the head gasket were plugged.

This is the coolant that came out of it.

It was pure liquid when it came out but, this is what it has become after sitting in a bucket for 3 weeks. It was like a giant jello experiment and we decided to mess with it some and it is now chunky style jello. INCREDIBLE!!!!!

It's total crap, the only way I'd use it would be if the car was on its last leg and I was getting ready to scrap it. Also I think you are supposed to drain it after X amount of hours so that doesn't happen.

2 bottles of that crap, geez.
