Truck Coolant Leak Repair Service in Tennessee & Mississippi

For professional truck Coolant Leak Repair Services from expert diesel mechanics in Tennessee & Mississippi, call Specialized Truck Repair today.

Truck coolant leak issues can be very complicated. It can become a very expensive problem if you ignore a truck coolant leak for too long. If left unchecked it can ultimately lead to engine failure. Once a coolant leak starts rarely does it get better. No matter what radiator you have, whether heavy duty, basic or semi, your cooling system needs to stay free of leaks in order to operate well. A small leak can cause temperature increase, create an air pocket and lead to overheating.

There Are Primarily Three Places You Can Have Engine Coolant Leaks:

  1. External leaks
  2. Internal leaks
  3. Leaky rad cap

How to Find the Coolant Leak

External Engine Coolant Leaks

External leaks are the easiest to find, most of the time you will just visually see them.

The source may be:

  • Rad hoses
  • Water pump
  • Freeze plugs
  • Heater core
  • Radiator
  • Overflow tank
  • Cracks in engine block, cylinder head, intake manifold
  • Blown head gasket leak externally

Internal Engine Coolant Leaks

An internal leak  be noticeable, when the coolant level does not stay constant. Also, you find that you need to constantly refill the tank or your engine overheats.

The source of internal leaks could be the fault of:

  • A cracked block
  • Cracked cylinder head
  • Leaking intake manifold
  • Blown head gasket

Rad Cap Engine Coolant Leaks

If you have a leaky or weak radiator cap, you may have loss of coolant in the overflow tank. This could create an air lock in the rad as well.

Other Things Could Be:

  • The cap is not fitting property
  • If the cap is the incorrect cap for the radiator

This will also cause pressure loss and engine coolant leaks.

A minor problem can easily turn into major ones when overlooked. Get the problem stopped before it turns into a tow-in event causing even greater cost and downtime. Book an appointment today with one of our highly skilled mechanics.

We had our truck towed from the dealership.  We saved moneycoming here, even including the tow bill.  We also didn't have to wait 2 weeks like the dealership said it would take.

Brought my truck in because the air vents were not working right. When I turned on my heat it would blow cold out the a/c vents. The tech Kevin had my dash tore apart and fix the problem and had it all back together in an hour. Thanks for the great job.
