How To Fix A Lexus Coolant Leak

There are few automotive gremlins as troublesome as a leaky radiator. When you find a big pool of green liquid under the car, that is not a pleasant time. A coolant leak can be the result of a number of things, ranging from worn hoses, poorly tightened hose clamps, or a box of rogue highway nails. However, you can save yourself time and money if you spot the issue and are able to repair it yourself. Read on to learn more about how to fix a Lexus coolant leak!

What is A Coolant Leak?

A coolant leak can happen for many reasons, including a bad hose clamp, a blown radiator hose, or a warped head gasket. Sometimes, it is because a foreign object was kicked by the truck in front of you that penetrated the radiator. The resulting flow of fluid can overheat the engine, contaminate your oil, and leave you stranded on the road. None of those options are great for your car so we have to fix it.

Replacing The Radiator Hose

As the car ages, the rubber and plastic hoses that feed the engine vital fluids can become damaged over time. You will start to notice a few drops of coolant on the ground but it can turn into a flood. If that happens, you need to replace the hose.

Here are the steps to follow:

  • Let the car rest for ten minutes.
  • Pop the hood and then take out the radiator cap.
  • Find the damaged hose. 
  • Depending on where the hose is, you may have to drain out the coolant.
  • Unscrew the hose clamps at the sides of the hose.
  • Place two hose clamps onto the new hose and also the sides to their respective spots.
  • Then, tighten the two hose clamps.
  • Fill the radiator with fluid and tighten the radiator cap.
  • Turn on the car. Check the new hose for leaks. If it seems good then it’s done!

Replacing Damaged Hose Clamps

A car’s hoses are clamped down using hose clamps. As the car ages, the hose clamps can start to fail and release the coolant everywhere. This is how you can replace them:

  • Allow the car to rest and cool for ten minutes.
  • Pop the hood and unscrew the radiator cap.
  • Find the damaged hose clamp.
  • Depending on where the hose clamp is, you may have to drain the coolant.
  • Unscrew the damaged hose clamp, you may need to cut it.
  • Place the new hose clamp on.
  • Then, tighten the hose clamp.  
  • Fill up the radiator with fluid and tighten the radiator cap.
  • Turn on the car and let it work up to operating temperature. Inspect the new clamp for leaks. If everything is fine, then it is done!
