Fault Finding

 

 

CHART D1—Coolant loss

 

 

 
 

Cause 

Remedy 

Incorrect coolant level. 

Check the level. 

Coolant leaking from engine radiator. 

Visually inspect the radiator hoses and connections to locate the 
leak. 
 
If oil is present in the coolant, check for an engine oil cooler leak. 

External engine coolant leak. 

Visually inspect the engine and components for seal, gasket or 
hose connection leaks. Make sure all hose clips are in good 
condition and torqued to the recommended figure. 

Overheating or compression gasses leaking, 
resulting in loss through the radiator 
overflow. 

Refer to 

Chart D2.

 

Lubricating oil cooler leak. 

Check/replace the oil cooler. Look for coolant in the oil. 

Cylinder head gasket leak. 

Check/replace the head gasket. 

Cylinder head cracked or porous. 

Check/replace the head. 

Cylinder block coolant passages leaking. 

Check/replace the cylinder block.
