Re: Temp. gauge

Are you talking about a capillary tube sender unit, or an electronic sending unit?

Re: Temp. gauge

My PO put his electronic sending unit in these holes.:

Don't know if a capilaty unit would fit in there but it is a big hole. He had to use a reducer on the electronic sending unit.

Re: Temp. gauge

I was going to try to find an off-the-shelf (OTS) temp sender/gauge set where the sensor element was slim enough to slip into the OE sender hole. Then solve the fitting 'issue' by using a brass fitting of smae external dimesions/threads as the OE sender, then bore out and rethread inside to accept OTS fittings. (Plan B is JB Weld the fit-up together if the fittings prove too much a challenge/undoable.)

Don't know if this hare-brained idea will work, but until I get the OE temp/gas gauges 'fixed', at least it'll give me my temp reading (I hope).

Had not thought about the ports Mr. Strenk suggested... Those are promising ideas. Wonder how hard they are to get to w/ manifolds on and engine in Jeep? Those plugs might be a real PITA to get out too...

Looking forward to more ideas...

Re: Temp. gauge

The front one is easy to get to but they have been in there a long time.

Re: Temp. gauge

Yes, I have my aftermarket temp sender in the front hole shown. Fairly easy to get to from the under side. Plenty of room for the length of the sender.
As for the fitting idea for the stock location. My PO used a hodge podge of assorted fittings to get an aftermarket sender to screw in. The problem was that the fittings rose so far out of the head that the sender was actually above the deck height. I'm sure it wasn't reading accurately and I worried about the smaller fittings cracking under the excessive stress. [img]images/graemlins/grin.gif[/img]
