Gary,
Some good advise for your problem. I like the simple idea of a manual valve too.
I was off last Monday and tore out the entire harness that goes between the engine and car. Over the years there has been more things done to this little car, and I got tired of finding cut wires that didn't do anything anymore but were still "hot". So now the car is sitting in the garage with it's dash out, new manual
oil pressure, temp, and water temp gauges installed (but sensor bulbs not in place yet), new fuse block located, but no wires connected yet, new fan relay located, 2 mega fuses located in two 12 volt leads, one switched with the ignition key (40 Amp relay) and one always hot, each will feed a fuse block..... and a few other things here and there...... should only take about 5 or 6 hours to have a new harness created and installed and checked out.
I knew that if I started this project the weather would be just GREAT
you all can thank me for making the sun shine and the temps return to near 70's.......... Your welcome!!!
Have fun
