Inspect your engine bay, and see where the leak is coming from.If you can’t reach that value, or it drops after you reach it, this means you have a leak. Pump the pressure tester until it reaches the same pressure value that was stated on the cap.Remove the pressurized cap, and inspect the pressure amount that’s stated underneath the cap.This is where you will need to do the test. Determine whether your car has a pressurized radiator cap or a pressurized reservoir/expansion tank.Make sure you do this procedure when the engine is cold.

This is because driving an overheating engine will damage its internal parts, leading to an expensive engine rebuild. In this case, we recommend finding the leak as soon as possible and fixing it. If this is the case, you’ll notice that your engine temperature gauge will rise above normal when you’re driving. If the radiator or tank is empty, this means you have a leak that causes you to lose coolant rapidly to the point where it’s depleted. The car’s cooling system is a closed-loop system, meaning that the fluid is supposed to recirculate and they shouldn’t escape. If you have green coolant (or green antifreeze), then your leak is coming from somewhere else, in which case, you can ignore this and move on to the next segment.īut what if it turns out that your reservoir tank and radiator are empty and you don’t see fluid inside them? Well, this is confirmation you have a coolant leak. ![]() If you have red coolant, then it’s likely you have a coolant leak – especially if the coolant is below the minimum level in the reservoir tank. Open the cap, and inspect the fluid inside.Locate either the radiator cap or the reservoir/expansion tank.Checking the coolant while the engine is hot is very dangerous and can result in burn injuries. If you’ve been driving, wait for about 30 minutes for your engine to cool down.This is simple enough, here’s how to do it: Still not sure?

They’re largely similar, but red coolant has better antifreeze properties that last longer. We’ll start with your engine coolant.Įngine coolant mainly comes in two colors: red and green. So, we’ll take a look at the possible causes, and eliminate them one by one until you find the cause. There are several possible causes for red fluid from your car.
