need help, temp gauge doesnt read

[ANVIL]

ever since i swapped in my rb25det my temp gauge goes all the way up, past the H, as soon as the ignition is turned on. I replaced the sensor on the intake manifold, the one with only one wire with a brand new one (meant for my car, 89 sohc ka) and it still does the same thing. how do i fix this?

first of all the gauge cluster temperature sensor is not on the intake manifold. secondly sounds like a wiring issue, id check your ****.

the temp gauge in the cluster you are trying to read is coolant temp.. so check that sensor/wiring to find your problem

By intake mani I assume you mean in front of it on the coolant lines? Switching the sensor should be all you need so I'd have to agree with checking the wiring. Possibly the accessory wire or whatever they call the wire that tells the gauge how much to read is not properly run.

so I ended up getting an aftermarket water temp gauge. i have the temp sensor wired directly to the gauge and it still wont read!? the temp sensor is brand new. it reads the same as the cluster, as soon as its on it reads to the max? anyone have any ideas on whats going on??

[Joe]

you installed the new temp sender? the one for the gauge? or a factory one?
