Cooling System Problems

It is estimated that half of all engine failures are associated with cooling system problems, which is reason enough to have an auto technician analyze the coolant regularly.

This coolant analysis should include:

  • radiator pressure-cap test
  • thermostat check
  • pressure test to identify external leaks
  • belt and hose inspection
  • check of system pH and electrolysis
  • system power flush and refill
  • engine fan test
  • check of clamps, connectors, and radiator mounts

Because cooling system deficiencies affect all systems (including the engine, transmission, and hydraulics), averting/resolving cooling system problems can help improve the function of these related systems. When an engine or cooling system component failure does occur, coolant analysis can identify the root cause of the problem.

TIP: High coolant temperatures can affect engine-oil viscosity and lead to subsequent oxidation and eventual engine wear.
