Leaking coolant from somewhere

Hi,

Check around the radiator, radiator cap, coolant reservoir and the radiator hose connection(s) at both ends and also the engine block for stains the colour of your coolant. Also for splits/cracks in the radiator hoses.

Check for signs of water in your oil. Look at the dipstick and see if there are signs of water mixed with the oil.

If there are no signs, get your radiator pressure tested in case there are splits in the radiator core and it only leaks under pressure.

Worst case, (besides head gasket in engine) is if there is a leak in the heater, inside the cab under the dash. Try turning off the heater control. This should prevent coolant going through the heater radiator.

Hopefully this is of some help.
