Hi all
I have just overhauled my 2,25 ser III and have still got an overheating
engine up steep inclines.
My radiator is new, thermostat new, temp gauge new but the engine goes over
100'C up steep pass and when I switch off engine, 4 seconds later the damn
thing starts to boil and spews water out the cap.
I also have an oil cooler and the oil goes also to 100'C which is why I
switched off the motor in the first place.
Is this standard Landy problem or must I get thermo fan?
James

Have you checked for a blowing head gasket?

Also check the Radiator cap isn't leaking as you get similar symptoms..
though it shouldn't affect the oil temp. Is the oil contaminated with
coolant at all?

Sounds like the water isn't being pumped efficiently. A Series Land Rover
should not boil unless being driven very hard in a hot climate. With the
oil cooler, particularly in this weather, your vehicle should be running
cool.

If it was mine I'd be checking the water galleries and the water pump as
well as making sure none of the water hoses have kinked or collapsed
internally.

One other thing to check is whether the engine is properly tuned. That can
make a difference but my money is on it being either a blockage or broken
water pump (ie: the impeller blades have corroded away)

Check the ignition timing - my guess is that you've got it very retarded.

This is not normal for this engine. You have a definite problem, and I would
be checking the ignition timing first and fan belt tension. If this is OK,
look for problems with the water circulation and pressurisation, such as
the radiator cap, blocked passages in the block, soft hoses or loose bits
of hose in the system or possibly the water pump.
Unless you live in a very hot area (average temperatures commonly above 40C)
you should not need an additional fan unless you are using a PTO when
stationary.

New cap?

Take the thermostat out first and try it again. This is the cheapest and
simplest test first. It is not unknown for new components to be faulty.

I recently helped a mate who had similar symptoms, not on a LR tho. While on
the move the temp gauge read a little bit above normal but it didn't usually
overheat. When stationary leccy fan was coming on but the temp gauge slowly
climbed towards the red. Switch the engine off and after a few seconds of
gurgling the the water level slowly rose up in the expansion tank and it
poured out. The top hose was getting hot but the bottom hose didn't seem to
be getting as hot we thought it should. Turned out to be the water pump. The
impellor had parted company with the shaft!

Seems common on VW group stuff

Have you checked for a blowing head gasket?

Also check the Radiator cap isn't leaking as you get similar symptoms..
though it shouldn't affect the oil temp. Is the oil contaminated with
coolant at all?

You did check behind the coreplugs while you overhauled?

I have found a combination of problems which I think I have sorted
Thanks
