View Full Version : oil pressure & water temp senders -- 20R vs 22RE

Does anyone know if the oil pressure sender & water temp senders from a '95 22re will work with the guages from a '80 SR5 that used to have a 20R? Are the resistance ranges close to the same?

I need to get my gauges hooked up before I start the motor again.

go to kms get there hot rod gage set its a buck fity or somthin all the gages and senders included

or just buy the sender for the year of dash you have the sender holes in the block and manifolds are the same

but i already got a full set of gauges, and I'm way over budget on the rebuild as it is since I had to get bottom end done twice...[27]

ya I was thinking about doing that...

then do it the senders arnt that much i know it all adds up you can get a 3 gage colehers set from lord co fairly cheep as well fo like 50 bux its water oil and volts comes with senders i think pa sells the kiit as well

I was hoping someone might know so I can re-use what i got since its already wired into the harness. Just need to splice a wire in the cab to the gauge and i'm done.

Provided your using the acutal guage sensors there "shouldnt" be a problem. (As in an EFI engine there is 2 water temp sensors, 1 for the guage you see, and 1 for the EFI) Be sure to use the correct one. (The EFI one is typically has a green base and is located on the front of the EFI intake manifold, bottom half.)

As for the oil pressure sender. I have seen physically 3 different styles on 22R series motors. Now if there is a differance in their resistances I am not sure. If you wanna know if they will work I suggest hooking them up, and with the sensor out of the block, use an air gun set to no more than 90psi pressureize the sensor. NOTE: the case of the sensors must be grounded in order to see the guage move inside.

maby if some one piched in the oil pump drive we wouldent be having this conversation

??? I havent read the actual teabag thread. But is that what the problem was? I might have one around here if so. I dont get it thou, didn't Aaron rebuild the once running motor?

Was just reading the posts... Yeah that is unfortunate about the collar for the pump.

And yes Aaron I have rebuilt lots of 22R series engines. I have only ever put on assembly lube. When I rebuild engines, I am always paranoid that the pumps wont prime either. So before I start the engine, I always disable the ignition, and crank the engine until there is oil shows up in the cam area. Then go for ignition. But ya know, of all the engines I have rebuilt... I cant think of one that didnt prime up right away.

Anyways, good luck and if you need parts, I always have stuff around.
