Morris Minor Owners Club

The Minor cooling system is WAY over specified.......

It was 50 years ago, a lot of water has gone under the bridge since then!

As I do not have a heater fitted I installed my temperature sensor at the back of the engine.

I prefer to have the benefit of the heater... The engine soon tells you if it's overheating.

What country is this car in?

Note the heater can act as a secondary radiator if the temperature creeps up.

The car is in Port Elizabeth, South Africa .

It might be that the thermostat is faulty, if it only reads 72 deg.

That would be spot-on for a standard thermostat!

Got the full set now [frame][/frame]

Just need the ammeter now.......

Seen several solutions here. For the 1098 engine, is this the right location for a temp sensor?

Yes!

I bought a Smith temp gauge with sensor, according to the seller for a Mini. I expected the sensor would fit, but the thread is different. The sensor is from Lucas. Is it located somewhere else on the Mini?
I assume making an adaptor will bring the sensor further away from the main water flow, so that wil give inaccurate results. Any good suggestion?[frame][/frame]

Not like any Mini sensor I have ever seen.... Perhaps for a MINI ??? Not much use on your Minor I fear...

The bottom hose will give you an incorrect reading since it takes the cool water from the rad back into the engine. You need to fit the sensor to the top hose or fit a tapped thread into the header tank if there is room, since this will measure the temperature of the hot water from the engine into the rad. There is room on a Series MM or Series II rad

He means cut a bottom hose to use as a top hose, then fit the sensor in the pipe that would be from the heater.

My 1960 convertible has one of those temperature sensors with wire curled all round the length of the connecting line from sensor to gauge. It is obviously an "add on" and leads from a thermostat housing with an integral take off point. The thing is that it doesn't work. I have read somewhere that this is a mercury filled tube and presumably not available (H&S). Any ideas folks. Is converting to electric gauge the only answer? Chris.

The temperature gauge you are describing is of the capillary type.

If the gauge is not working you will have to replace the complete gauge, capillary tube and sensor.
New Smiths capillary gauges are available at a price but fitting an electric transmitter and gauge is perfectly satisfactory and the electric type will be a lot cheaper.
