Re: UPDATE!!!!! IR temp measurements vs. reality

I looked at a cheap gauge previously. The sender didn't look like it would fit so I did not buy.

Question: Aside from physically fitting - do senders have to match the gauge or the engine? In other words - are all senders interchangeable?

They have to match the gauge. The only thing they have to do in the engine is have the proper thread.

Just pull the sender out of the engine and test it as stated in the service manual.
Here is a copy and paste from the manual.

Water Temperature Sender: To check water temperature senders,
remove sender from engine. Connect sender to a digital ohmmeter.
Immerse sender in a container of oil with a cooking thermometer. Heat
oil over a flameless source. Observe meter and thermometer. Meter
should indicate:
? 448 ohms ? 10% at 100? F (38? C)
? 128 ohms ? 7.5% at 160? F (71? C)
? 46.6 ohms ? 5% at 220? F (105? C)

they are universal. the kit comes with adapters for most engines. the big diff is the price. the probe may be to long but it should come with an adapter to work..it basically is a thermometer.


let us know how this works!!

deadstick is talking about a mechanical gauge, not an electrial gauge with a sender.
