What is a Head Gasket?

Welcome to Mercie J Auto Care, Where Compassion and Craftsmanship Come Together. Rick Smith, Certified ASE Master Technician and owner is here today to show you what a Head Gasket is. Now you may panic when you hear how expensive it is to replace. Basically the head gasket seals between two major engine components. Your cylinder block, which has the pistons inside and your cylinder head which sits on top. Your head gasket sits in the center of your engine, which is why it is so expensive to replace. It seals the area around the pistons and your radiator fluid or coolant goes around that to keep the heat off of your engine. So when this begins to leak internally, we start to get hot combustion gases from the engine running into the radiator or we get coolant into the cylinder. Is there's any other questions you have please feel free to shoot us an email or comment below.

Why do my Car Battery Terminals keep Corroding?

The problem with battery corrosion is that it can eat away at your Battery Cables and other components under your hood. Corrosion is kind of like cancer. While we cannot get rid of it completely, we can keep it at bay. How does corrosion happen? Well there is acid inside the battery. The battery is plastic, but coming out of the battery are metal posts that we hook the cables to. Where those posts seal to the battery we often have a little bit of leakage where vapors come up and cause the corrosion. The best ways to clean the battery is tons of water. The second thing we can do is disconnect the cables individually and wire brush the terminals on both sides. Then just keep maintaining it!

What causes a Fuel Pump to go bad?

Have you ever seen the fuel pump on your car? It's not likely that you've ever seen it because its located inside your fuel tank. When your fuel pump quits, so does your car.

Here are two tips from Rick Smith, certified master technician. 1) Your fuel pump sits in fuel so keep your car above 1/4 tank so it runs cooler and lasts longer. 2) If your car has an external fuel filter. Replace that regularly helps extend the life of your fuel filter. We hope this video was helpful. Please join us next time.

Why you should NOT leave your car on at the gas station.

 That’s why I have
this scar on my cheek.
Believe it or not, liquid gasoline is much less volatile than fuel vapors. Just because we don’t see any gas
on the ground or have not spilled any doesn’t mean there is no danger present. Keeping the car off
reduces heat and the chances of spark that may ignite the fuel vapors that are produced during fill up.
Also, we have emission components on the car that may be open while the engine is off, but closed
when not running. If we get raw fuel into those parts, they may become damaged, which is not as bad
as a fire, but certainly hazardous to the bank account. This is also a reason you should not top off your
tank once the pump has hit it’s shut off point.
I’ll tell you the same thing I tell my grandkids every time we say goodbye. “Make good decisions”
Until next time, safe travels and blessings to you.
