Radiator Cleaning

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

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

NOTE: 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.

IMPORTANT: 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.
