The leak tester uses a test liquid (not included) that changes color when there is CO2 in the cooling water. Added fluid to the tube as directed and popped this into the radiator header tank, within 2 minutes this great little kit had confirmed my worst fears. If a combustion leak is present, a small amount of exhaust gases is leaking into the cooling system. The cooling water is fed through the test device with a pump, and the application is as simple as it is effective. Best check is a combination of tests, from bubbling header tank water to the good old mayo in the oil.

The lambda probe tester and simulator tests zirconia and titania lambda sensors and the ECU (engine control unit, which monitors the parts necessary for the proper operation of internal combustion engines for proper performance).I spoke to a second garage (an MG specialist) who said testing emissions to determine whether the head gasket had gone was worthless and they never do it. variance in two adjacent cylinders (compared to the other cylinders), then the head gasket is most probably leaking.

Place tester with Large Engine Adaptor plate, on top of radiator opening, press down firmly to seal, and perform test.

If radiator opening is greater than 1 3/4", insert combustion Block Tester™ into Large Engine Adaptor plate (which may be purchased as an accessory).

Compatible with Alfa Romeo, Audi, BMW, Chrysler, Fiat, Ford, Mercedes, Seat, Skoda, Smart, PSA, Volvo, VW. Even small leaks, which only occur with high combustion pressure and high loads, can be detected quickly with the set without having to carry out time-consuming dismantling work. Just to confirm - in this case should I put this tester in coolant reservoir neck instead of the non-existent radiator neck?This crankshaft seal installer tool is designed for Volkswagen, Audi, Skoda 16v 1,4, 1,6 engines and it’s also used on Fiat BAG 1,6 engines. Just as a note, the thermostat won't keep combustion gases from entering the cooling system, it just won't circulate the gases forward to the radiator, but rather just run them around inside the engine instead. Problem is you have water > oil and vice versa, and then cylinder to oil exclusive, and/or cylinder to water exclusive, or a combination of all three. Any other precautions I should take with this test besides the well-known one - don't take off the radiator cap if the engine is already hot? Combustion process produces (beside others) 13-14% CO2 in the exhaust and the leakage of this gas in the cooling system is easily detected.

Draper Expert quality, block or combustion leak tester for determining if CO² is present in a vehicle's cooling system.Also, the lack of filtering could lead to false test results, the test fluid might not change colour due to possible contaminants. This tool is designed to extract the front oil seal safely and efficiently without causing damage to the seal or the crankshaft. The adapter is made of a special rubber mixture resistant to high temperatures and appropriately soft - thanks to which it fits tightly to the filler and the tester's tube guaranteeing 100% tightness during the test. This tool is designed to check for the leaks between combustion and cooling system of water-cooled engines. The first kit I got the liquid was contaminated and already green, but I was able to sent it back and get a good kit that worked like a charm.
