Cooling System Radiator

Cooling System Check-Up

A properly functioning cooling system is more important today than ever before due to engine designs & heavy stop & go traffic. Each engine operates best within a given temperature range, and the cooling system plays a key role in keeping the engine within that range. Inspection of the cooling system is usually not time-consuming and involves visual inspections of several primary components.

Hoses

Radiator hoses deteriorate with normal use from flexing, vibration, high temperatures and chemicals in the coolant. Check them for cracks, brittleness and swellening, because with these conditions they could fail at any time.

Radiator cap

The cap is not just a radiator cap anymore. It pressurizes the system & raises the coolant's boiling point to prevent overheating. Check the cap gasket for cuts, brittleness and spring pressure with a cap tester. Replace the cap if it cannot hold the rated pressure.

Coolant

Check fluid for contamination and flush the cooling system if necessary. When topping off, ensure the system is filled to the correct level.

Drive belt(s)

Inspect drive belts for glazing, fraying, cracks, and other signs of deterioration including the belt tensioner by pressing down on the belt about midway between the pulleys. It should deflect approximately ½” to ¾” of an inch.

Fan blades

Check the blades for cracks, bends and loose rivets. Never straighten a bent blade; instead, replace the fan. If the straightness of a blade is in question, remove the fan and lay it down on a flat surface and recheck. Replace the fan if any blade is more than 3/32 of an inch high.

Fan clutch

Check for "oily" streaks on the fan clutch housing that indicates a silicone leak from the fan clutch. Check the clutch bearing by trying to move the fan and clutch assembly from side to side. If the tip movement in more than ¼”, the clutch bearing is worn and should be replaced. Bring the engine up to operating temperature and turn it off. Spin the fan blade with your finger. If the fan rotates more than two turns, the fan clutch is freewheeling and the unit should be replaced.
