How to test for a blown head gasket with a block tester

!!!WARNING READ ENTIRE DESCRIPTION!!!!

In this video I'll show you how to used a block tester to check for combustion gases in the cooling system. Combustion gases found in the cooling system are usually the result of either a blown head gasket, cracked head or cracked block. When these gases come into contact with the block tester fluid it causes it to turn from a blue color to a yellow color. Using a block tester is a great way to determine if you have combustion gases in the cooling system and is a great way to gain a little piece of mind about tearing down the engine to fine the leak. (Further testing will be needed to determine the exact source of the intrusion and this video does not explain how to do this)
