Cons of Head Gasket Sealer
1) Head Gasket Sealer Produce Problems
As we discussed above, the head gasket sealer is used to stop the leaks of the engine head gasket. This sealer is a mixture of different liquids. As the engine gasket leaks, the sealant pours into the engine, which seals the leaking area and stops the leak. However, this sealer may also generate different problems.
The main disadvantage of the head gasket sealer is that it may create an overstressed or too tight seal. Due to this overstressed seal, the engine water pump may pump water into the engine. This water may trap in the head gasket by virtue of the seal formed by the gasket sealant.
The compatibility of the head gasket sealer with your car head gasket is very important.
If you don’t have to confirm whether your car is compatible with the gasket sealer or not, it is recommended that you should contact a mechanic before using this product. If you notice an unpleasant odour or leak from the engine, you should consult your specialist to see if the leak is due to the gasket sealant.
If your car gasket sealer is leaking, you should change your head gasket. But if the sealant is incompatible with your vehicle, you should contact a specialist to remove this sealant.
3) Malfunction in the Spark Plug
The spark plug is very important in the case of a petrol engine. Without a spark plug, the petrol engine can’t combust the air-fuel mixture.
Your vehicle spark plug can fail if you use a head gasket sealer that comprises silicone. The reason for this is that the silicone may move into the electrode area of the spark plug and create a thin layer that may stop the spark from moving through the gap. Therefore, after using the head gasket sealant, it is difficult to start the car. It can also wear out the spark plugs and cause premature engine failure.
4) Limited Use
The head gasket sealers are used for limited engines. These sealers are not compatible with all types of engines. It means you can use them for only specific engines.
5) Radiator and Heater Core Clogging
The main disadvantage of this sealer is that it may clog the heater core or radiator. If it clogs the radiator hoses, the cooling system of your car engine will not work properly, which may cause engine overheating.
The heater uses a heater core to transfer hot air inside the car. If the sealant clogs the heater core, the lines through which the heater core gets hot air will be clogged. If the lines block, the heater can’t get hot air by the engine and can’t send hot air inside the car.
