When to release the cap on the coolant reservoir?
Since the radiator, and especially the coolant reservoir, will be under pressure when the engine is in use or has recently been turned off, be sure to complete this step when you are sure that the engine has cooled completely. Relieve any pressure in the radiator system by releasing the cap on either the radiator or the coolant reservoir itself.
What does it mean if your coolant reservoir is cracked?
Radiator pressure tester. A crack in your car’s coolant reservoir can mean bad news for the safe and efficient operation of your engine. As your engine heats up during operation, the coolant reservoir serves as a temporary container for your car’s coolant as it is expelled from your radiator.
How is the coolant stored in the radiator?
Then, when the temperature of your engine cools, the stored coolant is replenished into the radiator itself. Although it is relatively easy to diagnose and even fix a crack in your radiator reservoir, extreme caution must be taken due to the intense pressure that this component is under during operation.

Where is the coolant expansion tank on a pelican?
Working at the top of the coolant expansion tank, using a flathead screwdriver, release the upper hose retaining clips (green arrows) by prying up. Lever the clip up until it reaches the stop (yellow arrow). 8-cylinder engine: Models with an 8-cylinder engine have two hoses at the top of the expansion tank.
Do you have to replace your coolant reservoir?
However, due to its design, location and material, the coolant reservoir is also susceptible to wear and tear and in many cases may crack or develop leaks. If this occurs, you’ll have to replace the coolant reservoir: a rather simple process that most DIY mechanics can complete without too many complications.
How do you change coolant in a 6 cylinder engine?
6-cylinder engine: Models with a 6-cylinder engine have a single hose to the top of the expansion tank and a cap. I suggest replacing the cap when servicing the tank. Working at the top of the coolant expansion tank, using a flathead screwdriver, release the upper hose retaining clips (green arrows) by prying up.
