156 JTD engine temp.

My 156 1.9JTD has, in the past couple of days, started
displaying highly variable engine temperatures.

I noticed it first on Sunday, driving up quite a steep
winding hill stuck behind a car doing <50mph, the temp went
up to 3/4

Today on a mixed run of high speed A1 and slower A roads it
seems to shoot up the scale when driven slowly (sub 50mph)
and on 2 occasions lit up the red warning LED.

Any suggestions? is it something that needs attention or
'do the all do that'?

This sounds reasonable.

This doesn't - if you're getting red warning lights you're in trouble, or
there's a problem with the warning light system.

Agreed.

Less likely on a 156 than on one of my older ones though, TBH.

Rob, you *have* checked the coolant?

Possibly sticking thermostat IWHT.

A *little* below min. in the expansion tank, but not so low.

Do they have such devices these days?
I thought it was all pixies in wires!

Heh. I don't think so. ICBW though.

Look at the radiator fins, our Spider had the same symptoms recently, and
the thermostat is six months old. The radiator was knackered with the lower
section losing fins and looking a right mess. New one cured the problem.
