However, it will turn into a bigger trouble if it goes unnoticed due to irregular maintenance. Let’s check out the symptoms of a cracked head gasket.

You just have to add the sealer to the radiator and the leak will be sealed as you drive. The type of the sealer will depend on the member of engine cylinders and the size of the leak. Normally, the sealers will work in the case of small leaks.

    It’s interesting to read about some of the common symptoms of a bad head gasket. I’ve noticed a lot of smoke coming from my car and I’m concerned that it could be the gasket. I’ll have to look into getting a new one as soon as I can to make sure I can continue driving the car without ruining it.
