i have a 94 devile with the northstar engine. today on my dash the engine coolant hot was displayed and after 5 min or so it started to overheat..pulled over and saw coolant comming out of the overflow..my fan was working, so could it be a thermostat issue or water pump issue??? any thoughts on it would be great..thxs in advance...

Belt tensioner, cap, purge line, thermostat are all potential culprits. Water pump is the least likely.
