## Overview

The RELD Cylinder Head Gasket Tester is a professional-grade CO2 leak detector designed for liquid-cooled petrol, diesel, and LPG engines.

## Description

The RELD tester is used to detect damage to the head and head gasket of liquid-cooled internal combustion engines (petrol, diesel, LPG). The tester has the same principle of operation and the same effectiveness as expensive testers and its price is affordable due to the innovative production method. In the event of a damaged seal under the head or the head itself, part of the exhaust gas contains, among other things, CO2 enters the cooling system. The operating principle of the device is based on measuring the CO2 concentration. At increased concentration, the reaction liquid reacts with CO2 and changes its colour. The whole process takes no more than 5 minutes and gives you almost 100% certainty whether the cylinder head gasket is not broken. The kit includes: Universal adaptor. The device for measuring tightness. RELD reaction fluid with a capacity of 100 ml. Instruction manual with steps to complete the test. You only need 2ml of reaction fluid to perform a test. Thanks to this, the set can be used up to 50 times. We attach a universal adapter to our RELD tester, which has a wide measuring range (25-55 mm). This allows you to check cars, trucks, tractor units, excavators, motorcycles, forklifts. The RELD reaction fluid is blue. If after completing all the steps described in the instructions (English language not guaranteed), the liquid has not changed its colour and is still blue, this means that your seal under the head and the head is in perfect condition. The RELD reaction fluid is yellow or green If the liquid has changed colour from blue to yellow or green after all steps in the instruction manual, this means that the seal under the head or head is damaged.

Review: Big leak - The bottle had lost 10-15% of its contents during before it arrived and the liquid was not blue anymore. Color was dirty and almost looked like the liquid had reacted allready. Price was cheaper than many other products, but I reccoment spending that little extra for a better quality kit
Review: Autant que je puisse en juger, le kit répond à mes attentes. Il est arrivé complet et facile à utiliser. La quantité de réactif est vraiment importante, on doit pouvoir faire une vingtaine de test sans problème.
