  • How A Coolant Reservoir Works - The coolant reservoir is a vital component of the cooling system. Its function is to store excess coolant fluid until required. Heat and engine vibration can damage plastic overtime causing cracks and leaks. This coolant expansion tank gives additional coolant a place to go after expansion and contraction due to temperature change.

This fits a Peterbilt 386 perfectly. It is an excellent replacement resevoir. There are no complaints with this product. It functions as designed with no leaks or issues.

My old one was cracked, needed a replacement. This one came in handy and about the same quality as the truck parts store. Same kind of installation as the old one and no issues.
