Why does my Mustang GT have a coolant leak?
This article applies to the Ford Mustang GT (1996-2014). If you own a car long enough, you are bound to have a coolant leak sooner or later. Over time and mileage, various cooling system components can vibrate, loosen, and lead to leaks. Similarly, rubber cooling hoses tend to break down and become brittle, thus allowing coolant leaks.
What kind of cooling system does a Mustang have?
The Mustang uses a pressurized cooling system with a coolant reservoir (a.k.a. coolant expansion tank). For this type of system, a small amount of coolant must be drained and the stop leak product of your choice added through the top radiator hose.
What can I do about a leak in the coolant system?
In many cases, items like a loose hose clamp, split radiator hose, or cracked coolant reservoir can be quickly and easily repaired, eliminating the need for any cooling system additives. Most external coolant leaks can usually be spotted by simply taking a quick look around the engine bay.

Why do I have a leak in my coolant tank?
If its a small leak, trace your hoses to find which one is causing an issue. Another potential source of a leak is the coolant overflow tank. This tank can also develop leaks over time due to heat cycles. Lastly, your overflow tank cap should be checked if you suspect your are loosing coolant near the overflow tank.
