Why is my engine temperature reading so cold?
The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself which is sending the information to the cluster.
Why is my car AC not blowing cold air?
The AC system in your car could go through all sorts of problems. One typical issue is the unit not blowing cold air, which could be punishing in hot weather. There could be several causes leading to this condition including compressor issues, low-level of refrigerant, trouble with the heater or AC controls, and others.
Why does the coolant temperature gauge stay on cold?
The most common causes of a coolant temperature gauge which stays on cold are with the coolant temperature sensor itself. It’s recommended to check this component first. If you have more questions about this topic, you are welcome to leave a comment below, and I will try to answer your questions as fast as possible.
What is the temperature of the coolant in an engine?
If your car model has two coolant temperature sensors, one is used by the temperature gauge, and one is used for the engine control unit. Engine temperature sensors are easy to measure with a multimeter, but you need to find the right values of them.
Why does the AC keep freezing up in my GMC Truck?
On cool with ac in the off position it blows REALLY cold air like as if ac is on. Eventually the air felt like it was freezing up and stopped then I turned to hot and blasted it. About 3 min and it came back. So SOMETHING is freezing up and making it just blow into the box and not out the vent.

When did my GMC Sierra air conditioner stop working?
I had a 2001 GMC Sierra that did this when truck was less the one year old (summer of 2001 is when it was). The dealer had the truck in the shop idling for a long time and the A/C worked perfectly. I told them to take it for a ride and see. So the service manager in an effort to convince me nothing was wrong went for a ride with me driving.
What does it mean when your AC hoses freeze up?
If anywhere before the o-tube you see an abrupt temperature drop from hot to cold, that means there’s a restriction in the line. That is caused from either moisture and/or debris in the system. before you do anything, I would but a set of gauges on it and observe high and low side pressures. that is free and may save you from wasting refrigerant.
