Overheating with Full Coolant
Hello All!
Been quite some time since I have been on this forum, but I have recently developed an overheating issue with my truck that has me stumped.
A little history on the motor: I have a 2000 3.0 V6. I originally had issues with over heating due to a leaking freeze plug and a bad water pump which resulted in a blown head in December 2016. At that point I had a new motor, water pump, radiator, thermostat, and hoses replaced.
I have only put roughly 17k miles on it and have had no issues until recently when I noticed the truck will start to overheat while driving in traffic or in the city. I live and work on the outskirts of town, so I do mostly highway or backroad driving with no issues, but when I do have to go into town it will start to overheat. The coolant level is still full. There is a little bit of brown gunk under the radiator cap, but the coolant is still green. I couldn't imagine there being a water pump or head issue considering all that was replaced not that long ago. Possibly just a cheap thermostat going bad?
Any help is greatly appreciated as I am unsure what to look at.
