where to run a copper hardline from driverside dash to passenger intake area

[Mr.PFloyd]

well i need some basic ideas of which hole i can route my temp gauge hardline through. yep its a mechanical unit so there cannot be extreme bends in the line, and i already fitted it nicely in the stock dash
So any ideas that will be relatively easy to run? i was thinking the passenger side firewall with the wiring from the ecu, but that little grommet is a bitch! also i think i would have to take out my dash to get to it... or would i?
any help is appreciated.

ps. dont tell me to get an electrical gauge lol.

also, my mileage is reading slightly weirdly since i pulled it. the numbers on the speedometer gauge are both slightly too high, will it bounce back down to the original position when put back in?

are you kidding? get an electrical one and do it that way.... they arent THAT expensive to go through the extra work and for it to have the chance to leak all in your cabin....

just saw your PS... oh well...GET AN ELECTRICAL ONE.

this one will not leak though, the copper just heats up and sends a signal from the little nipple that goes into the stock location. the coolant doesn't pass through it at all. I wish i got an electrical one at this point but i really didnt think it would be necessary. im sure someone here has ran a mechanical one...

Not only would you possibly get injured in a wreck, but you may also have 200 degree coolant spraying on you.

You should NEVER EVER run fluids into the cabin.

 

[Mr.PFloyd]

guys, yet again the copper wire just heats up and gives a readout. there is no coolant running through the car...

Coolant does not run into the cabin with the mechanical guages, like he said, it is just a probe that gets inserted into the thermostat area that heats up and sends the temp back to the gauge through the line.

Personally I agree with everyone else, get an electrical one. They are way faster, mechanical guages react to slow. By the time it read in the red zone it would be to late.

if you insist to keep it poke it through the speedo hole.

okay, heres a question. would anyone use the mechanical one over the stock one for the effort involved?
