My how-to: Water Temp gauge.

[FL_PR5]

if you look at what temperature reading it's in, such as C or F. it's right on.
and thank you.

Old thread, I know but I had a question. My dad and I were looking at my car earlier because I am having another issue but I bought a water temp gauge to install. I was looking at this howto and the hose that you guys are cutting into makes no sense for summer driving. That house leads to the firewall which leads to the heater core. The heater core is only used when the heat is on, otherwise it is bypassed. On our cars, the hose that is the highest on the radiator is the return hose. See, on other vehicles this is where the thermostat is but our thermostat is in the bottom. So, unless I am wrong, this hose makes no sense. Someone correct me if I am wrong.

Bump for an answer please...

Afternoon bump for an answer...

there is water running through the heater core all the time. I do not believe it is bypassed.

 

[dinux]

Anyone else??? BUMP

 

[Blake]

im positive there is water running through that section of the line at all times.

Ok, so I installed my gauge the other day. If I plug the ground into the gauge the temp reads at like 115 if I unplug the ground it reads 195. Anyone know what the hell the deal is? It is really starting to piss me off. I have a 182 thermostat if that makes a difference. Any help is appreciated. Thanks!

yes I'm bringing up an old thread. I want to run the adapter Tee off of the top end rad hose (next to the rad cap). Does anyone know the inside diameter of this hose?

 

[FL_PR5]

couldn't tell ya. not sure.

where can i get a sensor from? i think the reason mine stopped reason is due to using a buddies used sensor fitting. any suggestions?

 

[FL_PR5]

best bet i woudl say is ebay. still trying to fix mine... going to flush radiator and try something new. i'll keep you updated

anyway to tell if the sensor went bad? is there a specific test that can be done?

 

[blueprotegelx]

i found a sensor, but i was curious if anyone has gotten this to work for sure! i'm gonna wait to buy the sensor until i know this will fix my water temp gauge

For all of you that are having bad readings on your water temp gauge- did you ground the sending unit? Not the gauge itself (although that needs to be grounded as well), but the sending unit. If you install the sending unit in the middle of a rubber hose, it doesn't get a good ground- and the sendor works like a thermocouple varying the voltage between ground and the water.

My gauge goes up to 185 in the winter. I haven't driven with it in weather over about 50 yet since I grounded my sender.

I have the stock temp thermostat BTW.

 

[FL_PR5]

hm, that's a good point. I'm going to reground the actual sensor to the block and see if that helps after the flush.

 

[blueprotegelx]

did grounding to your block work? cause if it does i'm gonna have to order a new sensor as well and try it. but my car is sittin an hour and a half away while i'm in school so i can't try it myself!

 

[FL_PR5]

haven't been able to do it yet either. sucks driving around and not really knowing. i might have to order a new sensor too. i have to find some cable from a friend around here.

 

[blueprotegelx]

keep us posted. I may have to rewire the entire setup just to make sure everything is correctly wired. but i don't want to order the sensor until i know for sure this will work!
