Hi guys,
I have an LS1 V-8 conversion, and I'm using the console oil temp. gauge for coolant temp. instead. My problem is that when it's running at normal temperatures, the needle is at about 9/10ths, just short of the red region on the gauge face. I'd like it to be at about 2/3rds. Is it as simple as putting a resistor between the sensor and gauge, and how would I figure out the value of such a resistor? An adjustable pot? Thanks!! |

The best way is to use the sending unit that matches the gauge. The resister is series
will not report the correct temperature all the time. |

QUOTE(904svo @ Sep 25 2012, 01:58 PM)  The best way is to use the sending unit that matches the gauge. The resister is series will not report the correct temperature all the time. Yes.The way I did mine: Go to Eguages or an equivalent.Buy the correct sender for your LS(VDO style) I used the 120 deg sender,and bought the vdo temp guage (part#310-105) Wiring is dead simple. The stock plug fits perfectly.You have to swap 2 wires in the stock plug,the power and the sending leads.Thats it for the stock plug.The back light requires a ground(cause the new vdo has a plastic housing)I ran a ground lead to the nearest under dash location(Stock bolt) and done. Almost. The guage is smaller than the ones in your console.The guage has a threaded plastic ring that is used to seat the guage up against the mounting hole.This helps with the diameter problem.Spin it on.Now the guage is closer to stock diameter.The rubber mount you pulled off your stock temp guage is useful here. I tried to use it as is.Not a great fit.Take it and flip it inside-out.Viola!The whole assembly fits nice,and trims the guage face/retainer nicely.  And its tight as the rest. Needle is wrong color(or have the old ones faded (IMG:style_emoticons/default/confused24.gif) )but its not noticable while driving.It keeps temp perfectly.I have confirmed this with a temp gun repeatedly. (IMG:style_emoticons/default/smile.gif) Its a nice solution.It also(with a minor modification)fits the stock harness and location,and doesnt look out of place. It comes with 2 filters for the backlight.The green one is perfect. hope this helps! (IMG:style_emoticons/default/beerchug.gif) |
