CT3923 - 7pc Block Tester Kit

Detects exhaust gases in the radiator, which helps identify gasket damage, as well as cracked or warped cylinders.

Suitable for petrol, diesel, and gas-powered vehicles.

Works in conjunction with a combustion leak detector fluid (not included).

This tester detects even very small amounts of carbon dioxide in the coolant through a color change in the test liquid—blue, green, or yellow

providing accurate and straightforward diagnosis.

It features a conical adapter with a test fluid bottle and a quick-release adapter for direct connection to radiator adapters.

Compatible with sets CT1585 and CT3380.
