Engine Coolant Thermostat

Engine Coolant Thermostat: Get it Discounted Online

What is an Engine Coolant Thermostat and what does it do?

The thermostat keeps coolant from getting into the radiator before the engine heats up, thus keeping coolant out of the engine until it is up to temperature. This protects the engine from wear and keeps the emissions system running properly.

When should I replace my Engine Coolant Thermostat?

It’s time to change your thermostat if you are having problems with your coolant system, but it’s not often recommended as a preventative measure. However, it’s a cheap part that is easy to install so it is a good idea to replace it every 75,000 to 100,000 miles just to be safe. In addition, you can replace it anytime you flush the coolant.

What happens if I don’t?

If your car’s thermostat stops working, it will keep coolant from flowing into your engine. This means that your engine is going to be at risk of overheating, and if it overheats you can do serious damage to the engine. In other words, failing to replace a part that’s very cheap can cause damage that can be into four-figure territory when it is all said and done. Thus, err on the side of caution!

How to do it: Replacing your Engine Coolant Thermostat:

  1. Find your thermostat, which is normally going to be where the radiator hose hits the engine.
  2. Put a bucket underneath the area you’ll be working on to catch anything that gets loose so that you can return it to the radiator later.
  3. Take off the clamp and pull the hose off, preparing for some fluid to escape toward your bucket.
  4. Take the bolts off the keep the thermostat in place and lift it out of its housing.
  5. Make sure that your new thermostat and gasket match the old one in size and shape, so that you know they’ll fit. If they don’t, go get the right parts.
  6. Put the gasket in place and then drop the thermostat into place and secure it by bolting it down.
  7. Put the hose and hose clamp back on.
  8. Replace the fluid that drained out by pouring it into the radiator fill hole.
