Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

See kit contents below for all included components.

The coolant expansion tank provides a place for excess coolant to flow as temperatures rise and fall. Because it constantly endures extreme temperature changes, it’s prone to cracking or breaking over time. Keeping coolant contained within the system is essential, so if your tank shows signs of damage—such as cracks, broken nipples, or compromised mounting points—it’s time for a replacement.
