2014 jeep grand cherokee boiling only when towing, even after thermostat replaced. Any other clues?
You may need to upgrade your radiator to a heavy duty model made for towing.
Thanks for that, but surely the radiator should already be a heavy duty one. The car is just over 12 months old and has a 3.5 tonne towing capacity. It is the 3 litre CRDI.
The water pump could be the issues as well, but your SUV is fairly new. Have a mechanic check it out.
