When you service your Toyota Highlander radiator or engine fan, you may accidentally damage your coolant recovery tank, or coolant reservoir, as Toyota calls it. Even though replacing the coolant overflow reservoir is a fairly easy job to do on your Highlander, you want to do it right. Here's how to replace the Highlander coolant reservoir quickly and easily.
Instructions
Removal of the Old Coolant Tank
- 1
Turn off the engine and let your Highlander cool down for at least an hour. This allows the coolant to flow back into the radiator.
2Detach the coolant reservoir located on the right side of the engine compartment by loosening the coolant overflow hose from the reservoir and remove the reservoir. Be ready with a drain pan and rags to clean up any spilled coolant.
3Drain any coolant left in the tank into a tightly closed container for proper disposal.
Installation of the New Coolant Tank
- 4
Attach the overflow hose to the new reservoir and insert the reservoir into the engine compartment.
5Fill the tank to the "cold" line with Toyota approved pre-mixed coolant and cap tightly.
6Turn the engine on and let it warm up to check for any coolant leaks from the overflow hose, radiator and tank. If you find any leaks, check the overflow hose first and tighten hose clamps as needed until there are no leaks.
