Normal Operating Temp
Does anyone have a temperature guage with degrees rather than C N H ?
I wondered what the normal running temp for a '69 1098 mog should be ?
I've had nowt but trouble with the heater today, so have bypassed it completley I think the rotted heater hoses are filling the matrix up with cr*p, as the heater goes cold after a few mins driving and the engine temp shoots up
So, what temp should we be running at ? Does somewhere between 60 & 70 deg sound okay ????

The thermostat is something like 82 degrees.
Something sounds very dodgy - maybe the waterpump isn't working well? That would explain why the heater goes cold when the thermostat opens.
Would be worth checking the thermostat and the waterpump, and the heater hoses...
Crumbs you're having some bad luck!!!!

heater cold
Is your fan belt slipping?? With a Dynamo you should just be
able to turn the fan by hand. With an Alternator you should
NOT be able to turn the fan by hand. As RAYO says the stat
should be 82 degrees and the hotter an engine is the more
efficient it is (within certain limits) so your figures are too
low.

Gents,
With what I've had to sort out in the last 2 months, a water pump, fan belt, thermostat and replacing the heater (with the spare) are absolutely piffling in comparison !!!!!!!!
Anyway, WHAT ARE WEEKENDS FOR ?????????
Looking on the bright side, running too cool is less lightly to hurt than running too hot (as I found out with a cooked and heat siezed 1300 )

"I think the rotted heater hoses are filling the matrix up with cr*p, as the heater goes cold after a few mins driving and the engine temp shoots up"
Jim, if the matrix was blocked the heater wouldn't get warm in the first place. Perhaps your Minor's engine isn't getting warm enough (they are over-endowed in the radiator department). I had similar problems recently on the M4 cruising at 60mph when the temperature was just above freezing. Assuming you don't have a radiator muff, place a piece of hardboard between the radiator and grill, covering say 50-60 % of the cooling area. Drive around for a few minutes and then see whether the fan pumps out hot air.
Another clue might be finding yellow mayonnaise in the oil cap.

This would be around the oil filler cap.... this would signify a head gasket fault, ie oil & water mixing. This leaves a lovely thick creamy yellow / white scum around the oil filler. Which I ain't got so I'll relax on that one !racer wrote:So Whats the yellow mayonnaise signify?

Hi Alec,Alec wrote:Hello SM,
a heater that is warm then goes cold is often a sign of low water level, especially if the car then overheats. If you think there is oops I typed a naughty word in the heater, remove the hoses and flush out with a garden hose.
Alec
This is what we did when it first happened. Flushed everything, backwards, forwads and inside out !
Having put it all back together, I idled the car fo 10-15 mins and the heater got warm, engine warmish, then drove off. Half a mile down the road the heater got cooler & cooler... but the pipe from the head to the matrix was still red hot ! Could this be air ? How do you bleed the matrix to be sure of no air ?
Temporarily the heater has been bypassed and we have a little 30mile jaunt planned for today, so we'll see how it goes.

mayonnaise
CAUTION...........The Minor engine is well known to have a
tendency to produce mayonnaise(yellowish sludge in the
oil filler cap) and is is NOT always a sign of a sick engine.
It is usually produced when the engine is not used for long
enough trips to heat everything up properly and fast long
trips will usually clear out a great deal of this sludge. If the
engine is performing well then do not paranoid about this
mayonnaise.
