three days now and over a 100 looks and no one knows what this is?
thank you very much, I'm not getting heat in the cabin i figured this might be the problem the hoses get hot on one side of the pump and not on the other thanks again grmIt's called a "heater pump" and it's Nissan part # 92264-EA50B, which has been discontinued. To get it from Nissan, you have to purchase the whole heater hose/line assembly. It is available on the aftermarket, such as Gates # 41509E. Rockauto.com has it listed in the water pump section. It's used to help push the coolant through the heater core(s).
Most of the time, it's air trapped in the heater core that causes this and doing a coolant purge corrects this, but it's possible that the heater pump has failed. When purging, top off the coolant levels in the radiator and in the reservoir. Make sure the caps are on correctly; the cap with the spring goes on the coolant reservoir and the cap without a spring goes on the radiator. Jack up the front end of the vehicle as high as safely possible, or you can drive the front wheels on a set of ramps or park on a steep uphill, nose facing uphill. Start the engine and turn the front and rear (as applies) heaters to their hottest settings. Run the engine at 2500-3500 RPM for at least 10-minutes, or longer, as needed, until hot (approx. 140 degree F.) air is coming out of the heater vents. When done, lower the vehicle and turn off. Next time the engine is cold, double-check the coolant levels and top off as needed. Also, note the needle location in the coolant gauge when the engine is warmed up and also while driving. It should be almost dead center within the heat range. If you see it's staying near the cold side of the scale, you probably need a new thermostat (stick with genuine Nissan).thank you very much, I'm not getting heat in the cabin i figured this might be the problem the hoses get hot on one side of the pump and not on the other thanks again grm
