A coolant leak in a diesel truck can quickly lead to engine overheating, head gasket failure, and severe internal damage if not addressed. At Divine Fleet & Auto Repair, we specialize in diagnosing and repairing coolant leaks in light, medium, and heavy-duty diesel trucks.
If you’ve noticed puddles under your truck, low coolant levels, or rising engine temperatures, bring your vehicle in for a comprehensive cooling system inspection before it leads to costly repairs.

Signs of a Coolant Leak in Your Diesel Truck
Coolant Puddles Under the Truck – A green, red, orange, or yellow liquid pooling under your truck indicates a leak.
Frequent Low Coolant Levels – If you constantly need to top off your coolant, there may be a slow leak.
Overheating Engine – A loss of coolant prevents proper heat dissipation, leading to dangerous engine temperatures.
White Smoke from Exhaust – Could indicate coolant leaking into the combustion chamber due to a blown head gasket.
Sweet Smell Inside or Around the Truck – The distinct sweet smell of coolant could mean a leaking radiator or heater core.
Visible Corrosion or Coolant Streaks – Dried coolant residue around hoses, the radiator, or water pump suggests a leak.
Ignoring a coolant leak can lead to engine overheating, warped cylinder heads, and complete engine failure. If you notice any of these signs, schedule a coolant system inspection immediately.
Common Causes of Coolant Leaks in Diesel Trucks
1. Leaking Radiator or Radiator Hoses
-
Cracked Radiator – Over time, heat and pressure can cause the radiator to crack, leading to leaks.
-
Loose or Worn-Out Hoses – Rubber radiator hoses can develop leaks due to age, pressure, or improper connections.
-
Faulty Hose Clamps – Weak clamps can loosen over time, causing coolant to escape.
2. Failing Water Pump
-
Water Pump Gasket Leaks – If the water pump gasket deteriorates, coolant can leak around the pump housing.
-
Internal Water Pump Failure – A failing impeller or seal can cause coolant loss and overheating.
-
Coolant Seeping from the Weep Hole – A telltale sign of water pump failure.
3. Blown Head Gasket or Cracked Cylinder Head
-
Coolant Mixing with Engine Oil – If coolant leaks into the oil passages, it creates a milky white substance on the dipstick.
-
White Exhaust Smoke – A head gasket leak allows coolant to burn inside the engine, producing thick white smoke.
-
Loss of Compression & Overheating – A blown head gasket can cause performance loss and severe engine damage.
4. Heater Core Leaks (Cab Heater Issues)
-
Fogged-Up Windshield – A leaking heater core can cause a sweet-smelling mist inside the cab.
-
No Heat in the Cabin – A heater core leak reduces coolant circulation, leading to ineffective heating.
-
Coolant Leaking Inside the Cab – If you notice coolant pooling on the passenger-side floor, your heater core may be cracked.
