2001 Tribute - Radiator Light comes on intermittently
I have a 2001 V6 Tribute.
Noticed a couple of months ago the radiator light came on, but the temp still stayed pretty steady in the middle.
I had the radiator drained and fluids replaced, initially gave it a 3/7 litre mix of coolant/water. The light kept coming up, so I filled up 50% mix of water and coolant as per manual. It was ok for a while, but lately I have noticed that the light is coming up more frequently.
Does anyone have any ideas why the light would be coming up? the coolant/water is new and at the right ratio, and the temperature is steady and not overheating. But I noticed that in general the light seems to come up more when I am in heaving traffic.
Any help would be appreciated.
