Disconnect the battery first. Remove the guage by removing the 4 little nuts on the back. Be shure to drop at least one in your eye and another into the dash. Uncrimp the chrome ring and remove it and the glass. Remove the 2 small screws on the back of the guage holding the temp guage. Remove screws on one of the other guages next to it to ease removal of the guage. Now remove the sender from the block.....Follow the copper line into a large fitting. Coolant will probably pour out. If your old guage is broken, cut the capillary tube and pull through the firewall grommet . Remove guage from cluster. Carefully unroll the new guage tube and feed through the cluster, screw down temp guage and other guage. Reinstall cluster in dash reverse of how it came out. Feed new sender through firewall....remove grommet and push through firewall, then grease it up and stuff through the small hole in the 4 way grommet. Swear loudly. Try to resist the urge to cut the grommet if you can...they eventually dry out and begin to separate. Now carefully route your capillary tube to the hole for the sender. DO NOT BEND OR KINK TUBE. It is gas filled and once the magic gennie is let out, he doesn't come back. Insert adapter into hole in engine if needed, then thread in sender CAREFULLY. It is easy to over tighten and strip the threads..trust me. Snug it just enough to stop fluid leaks. Fill up radiator and check for leaks. Now drive it and check the guage. I believe I have pictures in the how to assemble an AD thread.
I went through getting one of the little nuts in my eye and losing another, my greatest concern was about having to uncrimp the retaining ring around the gauge assembly. Wanted to be sure that was required before performing that surgery. Thanks for the quick reply, will be doing it tonight.
