Aftermarket water temp gauge install adapter fitting
Someone wanted to know how to install a aftermarket temp sensor on a rx-7. Go to autozone and get this metric adapter kit made by Sunpro. Or you can order it here..
Order it here (model CP7574) |
I got mine at Checker (Shucks,Cragen). One of the local stores has a "speed equipment" section. They had it in stock. Another of the same chain "didn't have it, couldn't get it". About $7. Much easier than I'd thought, works great.

SWWWEEEETT now i can get my temp gauge working:D
|
Is that for electric or mechanical?
|
nevermind, it say mechanical. Crap, i have an electric. Any ideas?
*EDIT* maybe 7573 will work for me. which one fits 12a's - M14 X 1.5 to 5/8" x 1/8" NPT or M16 X 1.5 to 5/8" x 1/8" NPT |
i got a sunpro mechanical guage after the electric sensor broke reinstalling it after the rebuild. it came with the necessary adapters for me to install it in one of the threaded holes in the wp housing under the thermostat. just make sure to put some pipe thead tape on them.

Do you have to remove a stock sensor to get it to work? I don't want my stock gauge sitting there doing nothing... Even if it is inaccurate.
|
Pull out the sensor in the water pump housing then screw this adapter in. Then screw sensor into adapter. I'm using a electic guage.
To figure out thread pitch, just pull sensor and bring to parts store to measure it if you don't have a tap and die set. That's what I used to measure it |

I know the stock sensor is right under the oil cooler on the engine.
Thats what i thought you guys were talking about. Like pele asked - Is it alright to do it at the waterpump? |
Yes, thats how I did mine. I used the sunpro adapter for my mechanical temp gauge. Fits correct. The sensor your removing is for the choke. Its the switch that pops the choke off when the engine is warm.

Yes and yes. :D
We keep the fast idle linkage so you can have good cold weather starts. Once you remove the switch the choke hold stops working. What I did on the racecar is to cut off the leads on the switch and splice them together. Then plug it back into the harness. Then the magnet is energized all the time making the choke cable manually operable. I guess a toggle switch right near the magnet could be used to de-energize the magnet once the car warms up so the magnet isint always powered. |

RacerX7fb, that'd be great for an electric fan control... Might put it in the bottom radiator hose though. |

Originally posted by Pele But you said you remove the choke... So I don't need the choke hold meaning I can remove the entire magnet/cable assembly, right? RacerX7fb, that'd be great for an electric fan control... Might put it in the bottom radiator hose though. |
Originally posted by onepointone you dont want to do that, it would be getting a reading of water thats been cooled, not water thats coming out of your engine. you want it to be in the upper hose. If you're stopped, the wind doesn't cool down the water and the fan kicks on till the water cools... Once the water cools, the fan kicks off. Repeat as needed. You don't want the hot water straight from the engine to keep the fan running when you're on the highway. Most cars I've seen with temp sensors for the fan in the radiator have it in the lower end tank, near the nipple for the lower hose, or in the block where the lower hose connects to the engine. Originally posted by Rx7carl Nope, you still use the cable to control the fast idle function. Perhaps I can replace it with one of those lawnmower throttles... With the rabbit and the turtle on it. |
