Radiators

Keep Your Cool with a Genuine Chevrolet Suburban Radiator

The Chevrolet Suburban is the ultimate family hauler, but it generates a massive amount of heat. The radiator keeps it from overheating and is the frontline soldier in the battle against engine meltdown. If it starts to leak or the internal fins get clogged, you're looking at a potential head gasket failure that can cost thousands.

Radiator Problems to Look Out For and How to Fix Them

Coolant Leaks at the Plastic Seams

Usually means the end tank is separating from the core. The best fix is a new radiator.

Transmission Fluid in the Coolant

A "strawberry milkshake" look means the internal cooler has failed. Replace the radiator and flush both systems immediately.

Cracked Upper Hose Inlet

The plastic neck can become brittle over time. If it snaps, don't try to glue it.

Slow Coolant Loss (No Visible Leak)

Check the radiator cap. If the seal is worn, coolant is escaping as steam. The quick fix is a fresh genuine GM cap.

Bent Fins from Road Debris

If enough fins are flattened, airflow is restricted. You can try a "fin comb," but a new radiator is the better long-term solution. While the fan shroud is out, you have access to the serpentine belt, which you can replace during service to lower labor cost.
