Engine Temp gauge spikes.

[blk00z28]

(Mark correct me anywhere you'd like.)

Temp gauge is normal, hovers around the first line on the gauge off of 100. Driving around for a while, it will spike into the red for about 20 sec or so, and then come back to normal, then it will do it again about 5 min or so later. It did it to me yesterday 3 times. So I stopped to eat and let it cool down for about a hour, maybe a little more, just incase something was wrong, cause it was feeling kinda hot inside the cab. (maybe just because I had the windows down and the heat was building up from that.. city driving also.) Got back in it fired her back up and she was fine.

What could cause this?

The gauge?
The engine temp sensor? (if so where is it at, and how much is it for a new one?)

First check water level in your radiator..

Like kentuc said, check water level first. If that checks out it could be the engine temp sensor (driver side head - between cylinders 3 & 5)......PN TS253T - $15.99 (in stock).

Do you have a scan tool to check the temp when the gauge spikes up? My ty's been doing this for a while, but datamaster says the temp has never been over 165 when it has spiked, so I haven't worried about it too much. If I hit the dash when it spikes up, the needle goes back down to normal. The gauges in these truck don't seem to be of the highest quality...

I tryed that the first time it did it, and I had to hit it 2 times before it came back down. I was like.. ok maybe it just likes playing a game. When it did it again, I hit it, but it didnt do it. Same with the 3rd time. So :dunno:

I might as well just replace the sensor, its only $15 right Hood.. :lol:

Atta-boy.....I love that attitude, but it's also the same one that has me looking at my truck asking, "WTF happened to all of my money?"

ha, thats what I said about the AC selector valve that was $13. :lol:

So I guess I'll be sending you a check for this here within the next day or so as well Mike..
