There is a process that avoids specific head gasket problems. To do this, we use a head gasket leak detector. Let’s take a look at this effective process.

What is a head gasket leak detector?

A head gasket leak preventer is a liquid sealant that stops coolant leaks from the gasket. It is a sort of leak stop for vehicles.

Good to know: the stop leak head gasket is suitable for gasoline engines and diesel engines.

Cylinder head gasket anti-leak: types and characteristics

Head gasket leak preventer most often contains a sodium silicate-based formula. This product penetrates all the cracks in the car’s radiator and seals them by hardening them to stop the leaks permanently.

This stop leak is adapted to all types of vehicle radiators, in aluminum block or cast iron.

Good to know: the leak stop can be compatible with antifreeze and any coolant.

When should I use a head gasket leak detector?

The head gasket leakage stop is used when a liquid leakage is noticed in the cooling system or the cylinder block.

In most cases, the anti-leak can stop the flow of coolant when there is a micro-crack up to 0.75 mm long and 0.38 mm wide.

To determine the extent of the leak, run the engine for about 15 minutes. If the leak is small, the treatment can be carried out without fear, as there is no risk of overheating the engine, and it is not necessary to top up the coolant level.

Good to know: the head gasket leak stop is only used if the cracked part does not need to be dismantled. This is also the case when it is not necessary to call a mechanic. If in doubt, it is best to seek professional advice.

How to use a head gasket leak detector

Before using a head gasket leak detector, it is essential to let the engine block cool down completely before removing the radiator cap. When the liquid is boiling, it is likely to spurt out of the engine compartment, leading to severe burns.

Shake the product before pouring it entirely into the vehicle’s radiator and then :

    – Set the fan and heater to the maximum position.

    – Start the engine and let it run for about 15 minutes, then stop it after this time.

    – Top up the radiator water level if necessary.

    – Replace the radiator cap and allow the engine to cool completely before operating the vehicle.

Good to know: an anti-leak head gasket can be poured into the expansion tank when access to the radiator is difficult.

Head gasket leak stop: a maintenance solution

To avoid breaking your vehicle’s head gasket, it is strongly recommended to change the coolant every two or three years. Otherwise, the liquid becomes acidic, which can cause deterioration of the head gasket.

Good to know: It is generally recommended to regularly monitor the coolant level and quality by observing the expansion tank. If necessary, you should top up the coolant or have the tank emptied to replace the coolant.

Price of a head gasket leak detector

The head gasket leak detector is sold at car accessory stores, dealerships, garages, and dedicated websites. It is more often found under the name stop leak for the head gasket.

Its price is generally between $12 and $30 per 500 ml can.

Good to know: 500 ml of the anti-leak head gasket is the quantity needed to add to 10 litres of coolant.
