2005 mustang gt cylinder head temp sensor

I have a 2005 gt mustang which utilizes cylinder head temp sensor technology (not h2o censor). I have had consistent problems with it and do not trust it. Lets just say I'd like a back up. I'm thinking about installing a h2o gauage myself as a back up. Has anyone done this and if so where did u moount the h2o sensor and do they already have a kit for this. Any help is appreciated. Thanks.

Just put one of these into one of your radiator hoses and you can put your sensor in it.

Best is to mount it directly in a freeze plug in the block.

Since you have a 2005, your problems are probably due to a faulty stepper motor in the temp gauge, not the cylinder head temp sensor. A separate water temp sensor is still not a bad idea, but you may want to also get the stepper motors replaced in your instrument cluster.

Another option would be to buy a ScanGauge II and leave it plugged in to the OBD-II port. It reads the same inputs that are providing data to the car's ECU, and it can be set up to provide up to four gauge readings while you are driving.

An Aeroforce Interceptor would do the same.

Even if you fix the stepper motor in the panel the stock gauge is worthless. After my SC install the Rad fans were not working. I did not know it until I installed my Water Temp gauge the next day. The temp got to 240 deg around town and the stock gauge was happy stuck in the middle position. Dont know what temp it needs to show the needle on the hot side but it sure is nice to see the actual temp on the WT gauge. The stock unit is nothing but an idiot light with a needle. GA

+1... The OEM temp gauge is nothing more than an idiot light with a needle.
