aight, lovly truck has the Temp guage up with the compas. Problem beins that when it was 41 outside it told me it was 78, been doing it for about a week now. Whats the deal and how do i fix it? this is a 97

 

Do you have a cold front shield? I hear they can cause incorrect readings.

 

nah, its all open and what not. one day it just started climbin up, Anyone know where the actual sensing part is located? I heard up front so maybe its come loose and its against the radiator or something?

Not sure where yours is located because of the year but mine is right behind the grill in front of the radiator. Thats why cold fronts affect them, by making the air warmer where the sensor is. Maybe yours is dirty?

 

Could be, Im afraid of what it might be, I got the truck from the parents and they let me in on the secret that when it hit the deer it broke the first sensor. So when the great mechanic that replaced it, he just just the old one off and spliced a new one into the wireing. so i pry ahve some bad voltages there. Anyone use the Craftsman Multimeters? are they any good? Just askin for school actually. Im on strick budget. These things are like 50 bucks and for some reason they want me to buy this fluke meter, which im sure its better but i dont have 2-3 hundred to drop into one now haha.

 

My memory is not 100% on this, but the ambient temp sensor is located on the right radiator support (facing the truck), or in your case possibly in the center behind the grille. On your multimeter Q, for basic automotive electrical the Craftman meter should do nicely. Also Beckman makes a nice affordable meter.

 

The sensor on your '97 is a little to the center from being right behind the driver's side headlight. Check/clean the connection there.
