Hi all,
My brother's Frontier starts to head into the red on the temp gauge when at idle. As RPM's go up, the temp gauge goes back down.
I'm completely unfamiliar with these vehicles, but I know he's replaced the radiator and coolant within a year and has generally maintained it very well since new. More than 100k on it. He says no air bubbles in the system and coolant is full.
Could a partially stuck-open thermostat cause this?
Is there a temp sending unit that is known to fail on these engines?
Any advice is appreciated.
