If coolant is dripping from under your vehicle, but you can’t tell where it originates, then you may add a UV dye to the cooling system. Simply add dye, run the engine and then spot out the UV light to map you to Mother Ship Leak. This can be helpful for finding leaky freeze plugs or radiator pinhole leaks.

 If an engine is using coolant and overheating

 Coolant leak evidence is a mystery while overheating

If you answered “yes” to above then it’s likely an internal leak. In this case, a cooling system pressure tester may be an alibi. This tool hooks up to the radiator cap or coolant reservoir. You hand pump or use shop air to pressurize the system to its normal operating pressure (Northstars usually take 12 pumps regardless to use Blue Devil). And voila, if the cooling system can not hold pressure for 10 minutes then it’s time to consult your buddy “Ole Blue” for sealant magic…

or you can SKIP all the leak detection head aches and….
Pour N Go with Blue Devil and keep your fingers crossed for a miracle!
Sealed leaks happen about 90% of the time so keep the faith!

As you know, a little cool air on a hot summer day goes a long way. If you have ever been to Disney World in Orlando during the summer, I am sure you have purchased the rip-off of Mouse Land, the battery operated water fan. I have seen some tourist actually down right bathe with these small hand held propellers. Unfortunately you don’t have the mass luxury of singing sales people hypnotizing you to purchase this commodity. So how do you know when to be prepared for the loss of your A/C headed to the beach?

For starters, common sense says take your pointer finger, damp it and stick it outside. Is your A/C significantly cooler than the outside temperature? If you answer NO, then the most common diagnosis is a low level of refrigerant or coolant which is due to either a leak or a “time warp” since last fill. PS. If you are using birthdays as a landmark, please use the latter as your diagnosis.
To check the fluid level, look for the plastic “overflow reservoir”, check the level of the fluid there as well as the level inside the radiator when the engine is cold. If the antifreeze is dirty or rusty colored it should be flushed and replaced. Regular-life antifreeze is bright green in color; the longer-life antifreeze is red.

Recharging the refrigerant requires special equipment that the average customer wouldn’t purchase. There are a couple of things that you can do. First, make sure to have the system checked regularly according to your owner’s manual, and second, run your A/C system about 10 minutes per month, even when it’s cold outside. This might not make much sense in the colder climates, but shop technicians recommend running it because it contains a light mineral oil in the refrigerant that helps keep the compressor properly lubricated.

The best thing about air conditioning is you push a single button to make it work. Air conditioning systems are reliable if maintained properly. If you are a Go Green with maintenance then it must be a leak. So pull over and grab your savior, the Red Angel A/C Stop Leak, from the backseat and within 15 minutes you will be headed to the beach with A/C.

Spring Breaker Press Release

A. I recently had a reader try the Blue Devil product and so far the head gasket leak has been repaired. Just so you are aware, this is not just a “pour-in” product. You need to drain the cooling system, remove the thermostat, and add the product. Once the leak is sealed, you again drain and flush the cooling system, replace the thermostat, and add coolant. This is an ideal DIY’er project and, with the money back guarantee, you have nothing to lose but your own labor.
