Hey guys,
So I just bought my first Tundra yesterday. It's a 03 with 160k I got for $6500 (trucks are expensive in CO). It's got a couple small problems but one of the bigger ones that I really don't like is that the Coolant temp gauge doesn't work, at all. It is all the way down by the C pretty much sitting right over the screw in the console. Any ideas? I replaced the ECT? sensor and that did nothing so my guess is that it's the gauge itself. Anyone know how to get in there? Know how to check it or had similar problems? Haven't been able to find anything on here.

Thanks for the help,

Shaun

Oh, also is there a light or something that comes on if the engine is overheating? I just feel a bit uneasy without my temp gauge. I also read somewhere that the temp gauge doesn't have anything to do with the engine because the engine reads it elsewhere is that true? Or will the engine run differently because it can't tell the temp?

Thanks again!!

Oh also the battery gauge is not working, it seems maybe the lights dont work in the cluster and also the speedometer seems about 10 miles per hour over the speed. Speed thing could be because of bigger tires though? Maybe a fuse for the cluster is out? Truck sounds rickety but it's actually pretty nice other that these few issues and a couple small others lol.

Not that anyone cares, but I figured out what the problem was! I took apart the cluster and took out the temp and oil pressure gauge and then tightened up the little nuts and screws on the back of the gauge and it works now! Only problem now is that in the process the needle popped off and when I put it back on it was in the wrong spot I guess and normal temp shows almost in the red. Oh well. I'll have to take it apart later and center it while the temp is normal. Just glad to have a working temp gauge.
Just thought I'd let anyone in the future with this problem know what it could possibly be.

I’ve taken apart my gauges, did you remove the plate that all the solder joints are on?
