Cooling Systems & Radiator Repair

Your Radiator, Fans, Water Pump and Cooling system is vital to your vehicle and improper care can lead to very costly repairs. An engine that is overheating will quickly self-destruct, so proper maintenance of the cooling system is very important to the life of the engine and the trouble free operation of the cooling system in general.

Components of a Cooling System

  • Radiator
  • Radiator Cooling Fans
  • Pressure Cap & Reserve Tank
  • Water Pump
  • Thermostat
  • Bypass System
  • Freeze Plugs
  • Head Gaskets & Intake Manifold Gaskets
  • Heater Core
  • Hoses

One of the most important maintenance your vehicle needs is to flush coolant periodically. The reason for this important service is that antifreeze has a number of additives that are designed to prevent corrosion in the cooling system. Corrosion tends to accelerate when different types of metal interact with each other, this corrosion causes scale and build up that clogs the thin flat tubes in the radiator and heater core causing the engine to eventually overheat. Anti-corrosion chemicals in the antifreeze prevents this, but they have a limited life span.

Pressure Testing to Identify any External Leaks

Pressure testing the cooling system is a simple process to determine where a leak is located. A Pressure test is only performed after the vehicle has cooled sufficiently to allow the cap to safely be removed. A special tool is then used to apply pressure to the system, a gauge on the tester indicating how much pressure is being added per manufactures specifications. Once pressure is applied the technician inspects for leaks.

Internal Leak Test

If you are losing coolant with no signs of leaks its possible you have a blown head gasket, a technician will test this with a combustion leak tester. If exhaust gasses are present in the radiator you may have a blown head gasket. Replacing a bad head gasket requires major disassembly of the engine and can be quite expensive. Other causes include a cracked head or a cracked block, both are even more undesirable than having to replace a head gasket.
