I finally got three of the four gauges in my '49 GMC working. The final challange is the temp gauge and I had thought it would be pretty easy since the capillary tubes / gauge heads are available from several sources. However, I just learned that the early AD/ND GMC's had electric gauge heads...

I planned to bleed the brakes on my '49 GMC 3/4 tom tomorrow. Today I went under the truck to put some penetrating oil on the bleeder screws and was surprised to discover that the bleeder screws looked like hex head bolts with a hole in the center. I had expected to find bleeder screws with a...

The stock horn on my '49 GMC quit working and I'm trying to isolate the problem to the horn or the wiring/horn button. I know the horn is "hot" and the horn button provides the ground that activates the horn. But, my electrical troubleshooting is weak. I can't figure out how to test the horn...

Haven't used my timing light since the early 1960's. Got it out of the box to check the timing on my '54 235, but the instructions for making the timing light connections was missing. The lead for the #1 plug is obvious, but what are the connection points for the red and black clamp leads...

I'll be doing a tune up this weekend on my '49 GMC FC-152 with a '54 235 engine. I stoppd by NAPA this afternoon to get new ignition points and after doing the part # search on the computer the counter man asked me if it was a '54 truck or car engine... he had two different part #'s. I have no...

I'm fixing to do a fluid change in my '49 GMC 4-speed tranny. The "Owners and Drivers Manual" had a caution NOT to use hypoid gear oil in the transmission. I've been all over town and cannot find a non-hypoid gear oil. This is leading me to think ya'll must be running hypoid gear oil... or...

I will soon be ordering a new Temperature Gauge with sending unit for installation in my '49 GMC 3/4 ton dash gauge cluster. The engine in my '49 GMC is a '54 Chevy 235. Will the temperature sending unit that comes with the new '49 GMC temperature gauge match the size of the sending unit in...

None of the gauges in my '49 GMC 3/4 ton work so I'll be posting individually for help with each gauge to assist folks that come after me when they search the archives for help. The oil line that goes from the back of the oil pressure gauge ends in a broken line in the engine compartment...
