Water temp sensor won't fit with thermostats installed.

[Rled]

Hi guys. I have a 225 promax that was mounted on a one piece exhaust adapter with washers instead of thermostats and no poppit. I changed to a two piece plate with thermostats and poppit. Now, my water temp sensors, which were mounted in the top of the head, right behind where the stats go, won't fit. The sensor hits the thermostat. Does anyone know of a sensor that will screw in and not hit the thermostat? Thanks

They drilled and put the sensors in wrong spot. Need to be put a little farther back in that flat spot on head. Easiest way to fix would plug that hole and drill and tap a new hole in flat spot, that should put the sensor right behind the installed thermostats.

Thanks for the pic, I didn’t have one available

yes sir....

You can plug and redrill or get a shorter stem sender which will solve your issue. If it's an Autometer gauge/sender I may have the number in the garage.
Also keep in mind with a wet sender your temp will be approx 30* cooler than it actually is. So if your total works out to be around 145ish you will be good..

I'll buy new senders if I can locate them. So far I'm not having any luck. If you have info where I can get them, I would greatly appreciate it.

Try Ebay or call Autometer if you have their gauges. The sensors usually will work on other gauges just need to confirm temp so you could tell what temp you are actually running even thought the gauge maybe off 30*.

Thank you for the information. Much appreciated.

From all the reading I have done in the last year on water temp and all that with my 2.5's, I never read this that I remember. So on my 280 last summer with the sender in the top of number one I do not see the gauge move much at all, like 120 max on the autometer gauge, so I am really then at 150 is what your saying. Interesting, very interesting. Any specific reason behind this? Just lag or heat soak from the sender?

Yes, the actual water temp we have found it reads approx 30* colder them touching metal. If you have an inferred gun shoot the metal once the gauge reads the 120.
Basically you can put that sender to touch metal instead of water and it should give you a different reading as long as the sender is from Autometer.
Let me add. The drilled head system came on 245/260 motors (Nic) not (steel) so many liked that method so they started doing it. It work just need to know the reading is not the same.
