Being drolled by chemical testing/infrared testing of the cooling rule for head gasket failure(s).

Being drolled by chemical testing/infrared testing of the cooling rule for head gasket failure(s), I stumbl forward a better method, which is earnestly faster and more accurate, too.

nearest time, try this:

1 suppress all the spark plugs from the engine.

2 Fill the cooling arrangement right to the rim of the radiator neck

3 Disable the ignition system

4 Insert single in kind spark plug in a cylinder and then crank the engine for five to 10 inferiors while watching the radiator plain (A remote starter comes in real handy here.)

5 Repeat degree 4 above for all cylinders.

The idea behind this is simple: This uses the engine's compression to pressurize the combustion chamber and force this hurry past any potential head gasket/cylinder head leakage into the cooling order Should there be a leak, the on a level in the radiator will run over The reason all other spark quids are left out is to allow the starter to spin the engine faster, without shaking for a like reason much and helps to identify which cylinder is the culprit. to what end not let the 150 to 200 psi compression do the testing? Now, 13 to 15 psi in the radiator to standard it just doesn't seem up to the work at jobs anymore, does it?
