Q: Trunk popping open while driving

The drive belt on your engine is crucial – it runs all of your accessories, from the alternator to your power steering pump, water pump and more. While it’s designed to last for a very long time, it will eventually...

If your radiator is leaking then that will cause your car to overheat. The coolant system is pressurized so if it can not hold pressure then the coolant will begin to boil in the engine causing it to overheat. It...

Hello. This can be a module, but it can also be an issue within the system (https://www.yourmechanic.com/article/4-essential-things-you-should-know-about-the-heating-and-air-conditioning-system-in-your-car). I typically check the system pressures first. If the pressures are fine and are functioning right then the actuators under the dash need...

Hello, thanks for writing in about your 1997 Nissan Maxima. From what you've described you should have the front tires checked. One of them may have a broken/shifted belt. The tire basically becomes egg-shaped rather than round and can potentially...

Hi there. From the description you have provided, my thought is, your vehicle has a coolant leak (https://www.yourmechanic.com/services/coolant-is-leaking-inspection). Assuming you added to the cooling system, would account for the temperature gauge returning to normal and low coolant indicator going off....

The oil filter seal (to the block) could fail if the old seal was left in place and the new filter was installed over the old seal. In that case, the old seal will often dislodge and the oil will...

The blower control switch on the dashboard controls the circuit flow of the blower motor to adjust the voltage from low, to medium, to medium-high, to high. When on high, the circuit bypasses the blower resistor. The blower resistor will...

Hi there: The OBD-II error code P0420 (https://www.yourmechanic.com/article/p0420-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-1-by-jamahl-walker) generally indicates a Catalyst System Efficiency is below threshold (Bank 1). The upstream oxygen sensor is located in front of the catalytic converter. If the upstream oxygen sensor is working properly, its...

Hello, thank you for writing in. There are various reasons the vehicle would overheat, and the thermostat was a good place to start. You are also worried about the radiator, cooling fans, water pump, and engine block. You will want...
