Keeping it cool

Comments about Factory Air Coolant Temp Sensor Switch:

My radiator fans on my 2001 Chevy Malibu weren't working and car was running real hot. Fans would come on when the air condition was turned on. So I tried this temp sensor. Perfect fit and already had thread sealant on it. Easy to install. And best part was it fixed my problem. Car runs at normal temperature now.

Fixed temp gauge and check engine light problem. Have new one ready when taking old out. Only lost 1/2 pint coolant without draining system. Need swivel and long extension to get from inside tire well.

Comments about Factory Air Coolant Temp Sensor Switch:

Identicle to original Delco part. Tester said this was the part to replace. Symtoms included flooding when warm, poor starting and poor idle; engine light on. Flooded so bad when warm had to be towed.

Upon replacement, which takes about 2 minutes, engine light off and vehicle runs perfectly.

A very easy fix for less than $20, with a quality part that was easy to install.

      Hi Tom, I will be happy to help. Bad engine control module may also cause this problem. However, I would suggest that you take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.

  • Q:

    what is the coolant temperature sensor, and what is a air coolant temperature sensor? what one will fit my 1998 grand am 3100 v6 with a 195 degree thermostat??
    Asked on 11/29/2014 by sweet pea from north carolina

    1 answer

    • CUSTOMER CARE

      A:

      I'm happy to help, Sweet Pea! The coolant temperature sensor sends a signal to your electronic control module to adjust fuel injection and ignition timing. There isn't an air coolant temperature sensor. If you are referring to the title of this product, Factory Air is a brand name. The air temperature sensor sends data about the air temperature to also adjust fuel injection and ignition timing.

      This Factory Air Coolant Temperature Sensor (Part No. 36403) is the correct part for your 1998 Pontiac Grand Am 3.1L 3100cc V6 with the 195 degree thermostat. This can be verified by entering your vehicle information into the website, then checking for the green check mark for Exact Fit. In the Description tab under the Product Application(s) heading you will find any additional fitment information.

      A:

      Hi Rarefluke, great question! The coolant temperature sensor on your Isuzu Trooper should be located on the back of the intake manifold near the firewall. The best thing to do is remove the bolts that hold the tail shaft of the transmission, and jack up the transmission. That will tilt the engine forward far enough to be able to get right to it. However, I would recommend purchasing a Haynes repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair and replace specific parts or you may also get assistance from a certified mechanic in order to avoid intermittence.

      A:

      Hi Terry! I'm glad to be of assistance. It is used to measure the temperature of the coolant within the engine. The information gathered is then sent to the ECU or dash. This data from the sensor is then used to control the coolant fan.

  • Q:

    What is the difference in this switch and a Coolant Temp. Sensor??????
    Asked on 9/6/2013 by Rick from Pickens SC

    2 answers

    • CUSTOMER CARE

      A:

      With reference to your inquiry on the Factory Air Coolant Temperature Sensor - part# 36403, both coolant temperature sensor and coolant temperature sensor switch are same. It is used to measure the temperature of the engine coolant of an internal combustion engine. The readings from this sensor are then fed back to the Engine control unit (ECU). This data from the sensor is then used to adjust the fuel injection and ignition timing. On some vehicles the sensor may be used to switch on the electronic cooling fan. The data may also be used to provide readings for a coolant temperature gauge on the dash. For any further assistance, please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.
