I have a 2001 Nissan Pathfinder SE with 160,000 miles. I took my car in for an overheating problem yesterday after I noticed the coolant was leaking out of my car. I needed a simple hose repair to fix the leak problem, but now they want to replace the temperature gauge because they say that it is still running hot due to: "temperature gauge is stuck and not letting the cold water in." He said that he fixed the hose and it is blowing the cool air to the motor, so the only problem could be the temperature gauge.
Within the past year, I replaced the radiator and hoses. He is saying the temperature gauge + labor would amount to around $300. The car is probably worth around $2250 for a dealer trade-in. I am planning on trading-in the Pathfinder towards the purchase of new one once I am able to present it to the dealer in workable condition. Does anyone have a suggestion of what to do?
