How Can I Repair A Coolant Leak From My Engine?

ICoolant Leakf you have ever had the opportunity to look under the hood of your vehicle just after driving it you have probably realized that your car or truck’s engine produces a lot of heat.  That heat gets turned into power by the following cycle:

1)      Combustion occurs
2)      Heat from combustion causes gases to expand
3)      Expanding gases are turned into mechanical work through the pistons and crank
4)      Excess heat is rejected

Your engine uses the combustion of fuel to create heat and cause gases to expand.  The expansion of these gases is then turned into power to move your vehicle, but because of the way a car engine works, there will always be some leftover heat that can’t be turned into useful work.  This extra heat needs to be continuously removed to keep from damaging the materials your engine is made from, and to make sure the engine oil can do its job.

Today’s vehicles use liquid cooling systems to remove this excess heat because liquids are much more efficient at removing heat than air.  Your cooling system consists of heat exchangers or radiators, hoses, pipes, thermostats and a water jacket around the engine.  The places that connect each of the components, or seal them from other areas of the engine or vehicle, all are susceptible to failure and leaking, even under normal use.

The symptoms of a leaking coolant system are an overheating engine, seen by an abnormally high reading on your vehicle’s temperature gauge, or puddles of coolant under your car.  If you discover coolant leaking from your engine it often can be difficult to diagnose where the leak is or what component has failed.

The best way to repair a coolant leak from the engine is to use BlueDevil Pour-N-Go Head Gasket Sealer.  This sealer is designed to permanently repair leaking head gaskets, freeze plugs, heat cores and all other cooling system leaks.  There is no need to locate the leak first, just add BlueDevil Pour-N-Go and have a permanent repair – guaranteed!

For vehicles with larger cooling capacities or faster leaks, try BlueDevil 32 oz. Head Gasket Sealer.  You can pick up these cooling system sealers at your local Autozone, Advanced Auto, Pep Boys, NAPA, Car Quest Auto Parts, O’Reily Auto Parts, Bennet Auto Supply or Prime Automotive.

      1. I have a 1997 Subaru Outback 2.5 L engine. I have treated the engine
        with BD Pour and Go. Everthing is seemingly good except the fluid
        resevoir can oveflow at times after I have run the engine for awhile.
        No smoke from the tailpipe or any sweet smell just the fluid reservoir.
        Don’t really think it is bubbling it just want to rise up on me.
        Suggestions? note: put in a new thermostat and radiator cap.

        Thanks,

        1. Mark,

          Based on what you have stated, it appears the vehicle is getting combustion gases blowing into the cooling system and creating pressure. To give yourself the best overall chance of the product working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak. If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull. Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly.

          Feel free to contact us at 1.888.863.0426 with any further questions.
