But when something breaks you have to replace it by getting the best deal on Radiator Cap parts as possible.

Your vehicle is renowned for dependability and longevity, which is likely what makes you love it so much.
Your cooling system has dozens of small and large parts, but none are more simple and yet more important than your radiator cap. It keeps coolant in the system by maintaining the maximum coolant pressure in your GMC engine so that it keeps flowing in and out of the radiator and expansion tank. If it starts to leak, which they often do, then the level of coolant in the expansion tank will drop and you'll see it coming out of the top of your radiator. It is very cheap and easy to replace your GMC radiator cap, so don't delay any longer.
