How to remove the Radiator?

To remove the air conditioning system, start by discharging it if your model does not have an auxiliary air conditioning system. Disconnect the cable from the negative terminal of the battery and drain the cooling system. Remove the fan shroud and electro-viscous clutch, then raise the vehicle and support it securely on jackstands. Remove the lower radiator hose and the radiator support shield if equipped. Detach the transmission cooler lines from the radiator by unsnapping the plastic collar from the quick-connect fitting, removing the retaining clip, and pulling out the lines. Plug the ends of the lines to prevent fluid leakage. Lower the vehicle and remove the radiator support brace and coolant reservoir line. Disconnect the radiator side panels and remove the radiator. Before installing the radiator, replace any damaged hoses and hose clamps. To install the radiator, ensure it seats properly in the lower saddles and that the upper brackets are secure. Install the transmission cooler line retaining clips onto the quick-connect fitting and snap the cooler lines into place. Reinstall the plastic collars on the quick-connect fittings. Refill the cooling system and check the engine oil and automatic transmission fluid levels. If your model does not have a rear air conditioning system, have it charged by the shop that discharged it.

Chevrolet Trailblazer Radiator

In Chevrolet Trailblazer, Radiator is the major part of the cooling system which has the capacity to remove heat from the engine. It acts as a cooler, radiating heat from the engine coolant to the air through the core of the collection of fins and tubes. Several Trailblazer radiators use aluminum core with either plastic or aluminium tank while there are others that use copper with brass. Years later, there are performance radiators that are lighter than steel, and are made from aluminum and have better designs that can be used to enable better flow and better heat transfer of the coolant. This performance models have typically larger tubes and more fins compared to conventional radiators and hence have better cooling capacities. Standard direct-fit models are offered for the simplest assembly, whereas universal radiators are designed for special uses, including racing. In total, the efficiency of the radiator plays a pivotal role in temperature regulation of an engine and its performance.

Each OEM Chevrolet Trailblazer Radiator we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
