electrical. I presume you are neg ground y now so replacing it should not be that hard? When you say busted, do you mean does not work or samshed? If it just doesn't work check wiring before replacing. | ||

Actually, I think it was both. An electrical gauge in the dash and a mechanical gauge in the engine compartment. Jack | ||

Usually, there are a couple threaded (plugged) holes in the thermostat housing. Jack | ||

One fun part of electric gauges is the reading will change with the coach voltage, So if you know the usual cruising temp and oil pressure , seeing a major change , oil pressure drop , temp climb , it could just be the V reg heading south . So stop and feel the batteries before you boil them out!Don't ask, FF | ||

Whoa Fred! You just answered a question I've had for years on my electric temp gauge. I can drive the bus for about 2 hours and the gauge will stay at 180°. After that it slowly climbs to 240°..... Scary! I stop, run to the rear and the mechanical gauge is right on 170-180°. I've always wondered why and how it did that, now I am pretty sure I know! Thanks To Fast Fred, Here He is to Save the Day! | ||

I've seen some buses that have complete mechanical gauges in the engine compartment, or for that matter, you could setup a small space under the bed for a gauge cluster then have a video camera to watch the gauges at the dash. I know Yachts do this instead of having many different gauges at each steering station. Good Luck, TomC | ||

Someone along the way pointed out that a DD has two thermostats and two temperature gauges could 'head' off a problem. When I get around to updating my dash I think there will be two temp gauges if I can get those old plugs out of the housing. Don 4107 | ||

The sending unit(s) must be on the "engine" side of the thermostat itself. Otherwise you will never know when a thermostat sticks shut and the engine is overheating. G | ||

Good advice, George, I didin't even think about mentioning that. Maybe other models are different, but on our 8V71, all of the threaded (and plugged) holes on the thermostat housings are on the engine side. Along this same line, I have noticed that my right cylinder head is always about 5 degrees hotter than the left. Everyone else I have talked to that have dual temperature gauges has reported the same observation. The only thing we have been able to come up with is that the water pump is located on the left side of the engine, so that side gets water first? Jack |
