PERFORMING A BLOCK TEST

There are various techniques which can be used to determine a blown head gasket. Be very careful when performing these tests, when a vehicle has a  blown head gasket, the engine can overheat quickly. The cooling system can also build excessive pressure which could cause the cooling     system to rupture. Even a very small breach in the head gasket (often the diameter of a paper clip) will allow exhaust gases to enter into the coolant system. If exhaust gases are present, a head gasket repair will be required. A very common method to test for exhaust gases is a block test kit, which can be purchased for around $50 or most auto parts stores will provide the kit on a “loaner” basis. You will usally have to purchase the test fluid, the price is around $10.

To perform the block test:

1. Remove the pressure cap from the radiator or expansion tank, check to see that the coolant level is low enough to prevent any coolant from     getting into the test equipment (approx. 3″ below the fill hole). It may be necessary to drain enough coolant out to prevent the contamination of the test fluid.

2. Warm the engine, and allow it to idle during the test. Coolant must be circulating so the exhaust  gases can enter the cooling system while this test is in process. 

3. The color of test fluid before pouring it into your test equipment should be blue. If the fluid is green or yellow, the fluid is too old and should be replaced with blue test fluid.

4. Pour test fluid into glass tube to the fill line.

5. Insert the cone of the test instrument onto the neck of the radiator or expansion tank, insure there is a tight seal.

6. Insert the squeeze bulb into the top of the test instrument and squeeze it for about a minute to pull radiator gases through test fluid. If exhaust gases are present, the test fliud will “sniff” the gases as they are pulled through the fluid. If the blue fluid turns yellow or green, exhaust gases are leaking into the coolant system, and a head gasket repair is required.

7. If fluid remains blue, exhaust gases are not present in the cooling system.

8. If a blown head gasket is suspected, but the block test passes, it is possible that the head gasket breach is between the cylinders. Sometimes a vehicle can still have a blown head gasket without exhaust gases leaking into the coolant system. A compression test will be required.
