Morris Minor Owners Club

Hi, I'm thinking of fitting a water or oil temperature gauge - but not sure what the difference is... beyond the obvious! Which one gives the most important reading? Thanks!

You should fit an oil pressure gauge and a water temperature gauge, these are available separately or as a combined gauge. Capillary gauges are easier to fit than electric gauges which require a voltage stabiliser.
Oil pressure on a Minor should be 60psi running and water temp 80 to 90deg, depending on what thermostat you have fitted

Ditto.

Thank you, so as BMC has said on a previous post - the sender for the water temp goes on the thermostat housing - there is already an electric sender there actually, the car WILL be negative earth by the time I fit it... does that mean it still needs a voltage stabiliser / regulator?

The oil pressure sender... should that be capilary as well? I'm presuming then no electrics required except for a light bulb? And that, I'm presuming, goes on a 't' housing where the current oil pressure switch is? So you can still have the old one as well... correct?

Thank you!!!

hi not all electronic gauges (modern ones) require voltage regulators,read the instructions and specs and check before you buy and you should be ok
hope this helps

Smiths electric gauges require a voltage stabiliser. Oil pressure gauges are usually but not always capillary and if you fit a capillary temp gauge they will match. I have just fitted an elecric temp gauge to match the ammeter and I cannot get it to read over 55deg
