Necessary Steps for Replacing or Tightening Coolant Hoses in Chevrolet Corvette

If you own a Chevrolet Corvette and would like it to serve you well for a long time, then you will need to maintain it regularly. One of the maintenance measures that you should not ignore is checking the coolant hoses. You should replace the hoses at least once after every four years or whenever you see signs of wear.

If your model is later than 1999, there are chances that the drain plugs may be made of plastic, which calls for more attention when you want to replace the hoses. However, you can still perform the job by yourself with relative ease.

The basic tools you will use include a car jack, jack stands, knife, catch can, as well as either nut driver or pair of pliers. Here are the necessary steps.

1. In case you have driven the Chevrolet Corvette, let it cool for at least one hour before you start working on it.
2. Use the car jack to lift up the car behind the front wheel then place the jack stands to support the weight of the car.
3. Place a catch can or bucket under the radiator drain. Drain enough coolant to allow you to remove the hose without spillage. You need to remove just a little coolant if you want to replace upper hoses. However, you will have to drain the entire radiator in order to replace lower hoses.
4. If spring clamps are used, then use a pair of pliers to open the hose clamps. In case they are screw clamps then you should use a nut driver to loosen them.
5. Push the clamps to the center of the hose. Pull the hose to remove it from the nipple. It may be necessary to twist the hose for it to come loose. If this still does not do the trick, you may resort to cutting it with a knife and peeling it from the connection.
6. Slide the clamps onto the new coolant hose. Dip the ends into clean coolant and push them onto the nipples.
7. Use either nut driver or pliers to tighten the clamps onto the ends of the nipples. Avoid over tightening.
8. Refill the radiator with coolant mixed with equal volume of water. Tighten the radiator cap.
9. Check for any leaks after starting the car and add coolant as necessary.
