WARNING: This page is about a different car, the 2020 Buick Regal TourX, 2020 Buick Regal, 2019 Buick Regal TourX, and 2019 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

NEVER spray water on a hot heat exchanger. The resulting steam could cause personal injury.

CAUTION:

The heat exchanger fins are necessary for good heat transfer. Do not brush the fins. This may cause damage to the fins, reducing heat transfer.

NOTE:

Remove bugs, leaves, dirt and other debris by blowing compressed air through the engine side of the radiator.

Some conditions may require the use of warm water and a mild detergent.
Clean the A/C condenser fins.
Clean between the A/C condenser and radiator.
Clean the radiator cooling fins.
Straighten any damaged cooling fins.
