Want this question answered?
Depending on which intake manifold you have there may be a plug in it near the thermostat housing. Also, each head will have a plug on the side. One is usually fitted with the sensor for the original gauge. This is the usual spot for wiring in an aftermarket gauge.
Does anybody know the answer to this question??????? YES I HAVE THE ANSWER...REPLACE THE TEMP GUAGE. ITS NOT AS HARD AS YOU WOULD THINK...ABOUT A 20 MIN. JOB ------------------------------------------------ I tried replacing the temp gauge but that wasn't the problem for me. On top of the engine is a temp sender that is all so easy to get to but it is for the engine computer. The temp sender for the gauge is under the water pump. My temp sender went bad because the water pump started leaking. It is like the engine is headed for a major problem of over heating but it disables the temp sender which warns the driver of over heating. It is not easy to change the temp sender but it is doable if you pull off the thermostat housing. Don't put the old thermostat back in. Also, don't get an aftermarket temp sender, I got one and it reads 3/4 hot all the time. It only cost me $5 but I wish I had have bought from the dealer what ever it cost.
You can get gauges with instructions at auto parts stores Oil Pressure, engine temp, amps or volts
Put a 195 degree thermostat in it and see what it reads. Are you SURE the GAUGE is not LIEING to you ???
At the risk of being called "Mr Obvious" I would venture that you buy the brush guard from a reputable aftermarket suppier and then follow the directions. Wouldnt surprise me if some frame members will need to be drilled but then a good aftermarket product sometimes uses existing holes.
Say now, it is possible to dismantle the instrument cluster, and replace the gauge unit itself. Keep in mind that the price of a new one from a dealer may be steep! To put a mechanical gauge in may require drilling a hole in the firewall. Also, the computer may need to monitor the water temperature in order to function properly. If the temperature gauge is not reading, then I would suggest going to a parts store, such as Auto Zone, and getting an aftermarket temperature guage and hooking it up because there is no way to replace the factory gauge.
Your best bet would be to go to oreillys or auto zone and get a small gas gauge and unhook the wires from the gauge in your dash and run it to the side and put it by the pillar... I did the same with my temp gauge and it did fine, although if you want it to light up run a power and ground from the stock gauge too and you'll be good to go.
Warmed car to operating temp with fan fuse pulled. Turned off ignition. Removed battery cable. This resets the computer. Put batt cable back on and fuse back in place and started the car. Temp gauge started working. (Sensor has to see temp within short amount of time to operate the gage.)
yes
If you have electric fan, yes, there is a sensor for that, but it only operates the fan, nothing to do with the temp. gauge in the car. But, I think the problem might be with the wire to the gauge, or the gauge is not working. Instead of waisting a lot of time to find the problem, why don't you buy an after market temp. gauge for your car model. It comes with a new sensor, wire, gauge, and instructions. Find a good place in the car to put it, and this can be done within an hour. There are electric gauges, or mechanical gauges. Electrical is just to pass a new wire through the firewall from a small existing hole, or the mechanical, you have to pass the temp. bulb. from the inside to the engine comp. The elec. is easier, and reads very good. Hope this saves you some time.
I am answering my own question for others incase this happens to them. It was the temperature gauge for the computer (not the dash), but the plugs I had put in the first time fouled out and had to be replaced again when we putin the temp. gauge. truck runs great now. thanks anyway :)
my 94 camaro did that, check your gear pinions or put in a 3.73 aftermarket conversion. my 94 camaro did that, check your gear pinions or put in a 3.73 aftermarket conversion.
