I have recently done a bit of work on my 72 Mini 1000. 

I have fitted a new fletcher radiator, hoses and Thermostat

I ran the car for a few months and the temp gauge sat on around 80 /90 c and ran fine

 

I have since upgraded to a Minispares Stage 1 Kit, routing the Inlet manifold water intakes through the heater hoses on the tap side..,

I also fitted a new Heater Matrix

 

Car is running fine however the temp gauge now reads low 50s to 55. 

I am a bit concerned that there is something  wrong and I am not  getting a true reading

 

Any and all advice is very welcome

 

Kevin

Nicklouse. I managed to get some readings for you please see below

 

Readings were taken with an Infrared Thermometer and in Celsius

 

 

These readings floated about a bit but I would say plus minus 3c

 

Head 78.5

Top of radiator 37.0

Hose from heater tap to minispares inlet manifold 46.2 (left side)

Lower rad hose 39.1

Thermastat housing 61.50

Top rad hose 50.5

Inlet manifold housing 41.8

Inlet manifold to heater matrix 66.5 (right Side)

Nut on heater gauge connection on Head 70.1

Temp gauge in car floating around 50.1

 

Heater is blowing very luke warm to cold.

Sounds air locked to me, if in the UK you won't really benefit from having the water routed through the manifold

Not good to run an engine cold, makes it inefficient and the fuel washes the oil of the bores causing early wear and oil dilution. 

 

Need to run between 80 and 87 deg C. Thermostat could be faulty.

checked the heater matrix again...Manually pumped water through the matrix burping all air out and reconnected.. Didn't make a difference.. I ended up bypassing the Matrix by connecting a hose from the back of the heater tap to the outlet on the lower rad hose... Still didn't make any difference.. sits between 40 - 50 c 

When I disconnected the tap hose water was pumping through it nicely , So I know I am getting water flow,

 

Just don't understand how or why when I fitted the Stage 1 kit this has happened 

 

Starting to get on my nerves now..

For the sake of a fiver its probably worth swapping out the temperature sender in the thermostat housing. It may be just coincidence that you have been working on the engine.

If it was me, i'd also get a new thermostat while you are at it in case its jammed open.

thanks for that... I have the new dual Oil and Water Temp Gauge (capillary) fitted about 6 weeks ago, so I would hate to think its that..

Will get a thermostat from minispares, there goes my weekend of driving the mini unless local Halfords have one
