Bought one of BigMark's excellent quad gauges (oil temp, pressure, fuel and volts). When oil temp was connected to the 2 ltr four, when the car was cold, the temp would show zero and then gain as the engine warms. With the new 3.0 6, the gauge when starting a cold motor shows ~ 125* and then climbs from there. Seeing temps around 250+ can be a bit disconserting, until you do the math. BigMark doesn't have a solution for the gauge readings. I used a Porsche temp sender as well as one Mark included and they both read about the same.
Soooooooooo... any thoughts on how to recalibrate the temp gauge or sender to accurately reflec the actual temps? What is going on here? Much grass. |

Install an engine ground strap.
If the sending units are the same value and the only difference is the engine, it is a difference in resistance to ground giving you the reading. |

Unfortunately there is a ground strap from the trans to the underside of the rear trunk just behind the center of the muffler. Must be a compatibility problem between the sender and the guage - McMark, is there a specific rating or nomeclature for the gauge which must match the sender? |
