B1B Keven Posted January 17, 2017 Report Posted January 17, 2017 (edited) I thought I'd write up how I rebuild the temp gauges for our MoPars. Start by carefully cutting the outside protective wrap at about 40 inches from the bulb. Then coil the tube around your hand (starting at the bulb) and put it in an ice bath.

B1B Keven Posted January 17, 2017 Author Report Posted January 17, 2017 (edited) Cut the gauge as shown: Edited January 17, 2017 by B1B Keven Quote
B1B Keven Posted January 17, 2017 Author Report Posted January 17, 2017 Drill down the tube in the gauge about an inch (too far and you'll come out the front ruining the gauge). Use a tiny bit to start, finish off with an 1/8" bit. TAKE YOUR TIME. Cut a piece of copper 3/32nd tubing to 2 or 3 inches, put it down the 1/8th inch hole and solder. Use compressed air to make sure the needle moves. Quote
B1B Keven Posted January 17, 2017 Author Report Posted January 17, 2017 (edited) Pull the protective wrap down the copper tube toward the donor gauge and cut the tube. I like to use side cutters at this point so I don't lose any ether gas. Edited January 17, 2017 by B1B Keven Quote
B1B Keven Posted January 17, 2017 Author Report Posted January 17, 2017 (edited) Add a small amount of protective wrap to the tube in the gauge. Edited January 17, 2017 by B1B Keven Quote
B1B Keven Posted January 17, 2017 Author Report Posted January 17, 2017 (edited) Slide the exposed tube down the inside of the 3/32nd tube to check length (shorten if necessary). TAKE A DEEP BREATH AND RELAX. Take a pair of scissors and cut the small tube. Quickly insert it down the 3/32nd tube and solder. Edited January 17, 2017 by B1B Keven 2 Quote
B1B Keven Posted January 17, 2017 Author Report Posted January 17, 2017 (edited) With the bulb still in it's ice bath take the gauge over to a pot of boiling water. Unroll the coils made by using your hand and at the same time, put your nose near your solder joints and drop the bulb into boiling water. IF YOU SMELL ETHER GAS, REMOVE FROM HEAT, PUT THE BULB BACK IN THE ICE BATH AND CHECK YOUR SOLDER JOINTS. You'll probably get one more shot at the repair before you've lost too much ether. If you don't smell gas, CONGRATULATIONS!! Adjust the gauge as needed so it reads both zero (out of the ice bath) and slightly more than 212 degrees ( in boiling water).

B1B Keven Posted January 17, 2017 Author Report Posted January 17, 2017 (edited) Once done, put some reverse turns/twists in the protective wrap and let it unwind into the short piece you soldered on the gauge. Edited January 17, 2017 by B1B Keven 4 Quote
Los_Control Posted January 17, 2017 Report Posted January 17, 2017 Thank you very much for the great write up kevin \o/ I have read another article on this process, and it left me with questions. After reading this article, am ready to dive in ... Awesome and Thanks again. Quote
Brent B3B Posted January 17, 2017 Report Posted January 17, 2017 I agree, great write up Keven... although, I find it easier to just get in my truck and bring it to you 1 Quote
Don Coatney Posted January 17, 2017 Report Posted January 17, 2017 Add rock salt (not granulated table salt) to the ice bath. Quote
John Rogers Posted January 17, 2017 Report Posted January 17, 2017 Thank you for taking the time to do this Kevin. I need to do this to mine as well and actually seeing you go thru it step by step helps tremendously.Its one thing to read about the process but reading and seeing is much better and helps to make the prospect of performing the repair for the first time a lot less intimidating.

pflaming Posted November 2, 2017 Report Posted November 2, 2017 It's not very often when a professional repairman shows others his tricks of the trade. Kevin, you are one of very few. TKS. When my truck burned, Kevin sent me a complete new set of gauges and refused payment for them. Note the speedometer, he did that also. Quote
