When towing 2 ton, only 10 minutes, Temp hit 120 and coolants looks to have pissed out the bottom.
If the coolant is old would it cause the coolant light to always be on?
Other thought is, perhaps the fan is faulty, which causes the light to come on? I think the fan comes on under high/extreme heat and is checked as part of start up?

You will burn up both engine and transmission.

Thanks for the reply. Its appears the fan is not working. I had noticed it prior, but simply thought it only kicks in under high temperatures. But I was told it should spin at start up, might be just slowly. So that will be the issue. Have booked it in for fixing.
