Depending on how you like to take care of your car or truck, a few little leaks here and there might not seem like a big deal.  Regardless of what kind of car you drive or how old it is, a coolant leak, no matter how small, are always a big deal!  Coolant leaks lead to low coolant levels.  A low coolant level will lead to overheating, and overheating destroys engines.

Coolant leaks are often easy repairs you can do yourself and shouldn’t be neglected.  If your car runs low on coolant it may cause your vehicle’s temperature gauge to read incorrectly making impossible for you to tell if you are damaging your engine as you drive.  Checking your coolant level is the only way to ensure you’ve got enough coolant to keep your engine safe.  If you notice the level is getting low regularly then you’ve got a coolant leak you should get fixed.  Join me in the garage to learn how to fix the easy coolant leaks and when to take it to a mechanic!

Coolant Leak Locations:

  • Hoses
  • Thermostat
  • Radiator
  • Heater Core
  • Head Gasket

Hoses

Fixing a leaking coolant hose is an easy job you can usually do with a pair pliers and a flat head screwdriver.  Coolant hoses can get cracked on the end or bulge in the middle and develop leaks over time.  Leaking hoses are often easy to spot when your engine is very warm and your cooling system is pressurized because you will be able to see steam or bubbles coming from the leak in the hose.  Fixing the leak is as easy as grabbing the right hose form your local auto parts store, loosening the clamps, removing the old hose, installing the new one and refilling your coolant system.

Thermostat

The thermostat for your engine is housed at the end of one of your radiator hoses and will have a housing over it.  Often times the gasket or seal for this housing can leak due to the temperature differentials at the thermostat so this is a good place to check for leaks.  Replacing the thermostat gasket is an easy job if your thermostat is easy to get to.  If you have to use a liquid gasket maker to form a gasket make sure to let it completely dry before refilling your cooling system.

Radiator

Since your radiator is at the front of your car it can take a lot of abuse.  Also, if you’ve got a newer vehicle your radiator probably has plastic end tanks that can be prone to cracking.  Radiator repair can be done a few different ways so be sure to read our article on radiator repair!

Heater Core

Your heater core is just like a radiator but it’s under your dash to bring heat to your ventilation system.  heater core leaks often show up as coolant on the passenger floorboard or dripping from AC condensate drain.  Heater cores can be extremely expensive to replace due to their location.  If the hard part repair doesn’t make sense for your vehicle, you can try using BlueDevil Pour-N-Go to seal the leak in your heater core. 

Head Gasket

Leaking head gaskets are one of the most difficult coolant leak locations to diagnose.  Join me in the garage for a quick explanation of the symptoms of a blown head gasket to help find out if that is where your coolant leak is.  Just like a leaking heater core, a leaking head gasket can be an extremely expensive repair.  If that doesn’t make sense for your car, BlueDevil Pour-N-Go Head Gasket Sealer may be a great solution for your vehicle!
