Coolant system pressure "vs" gagging at high rotat
Hello,

This is my first time at the forum.

My name is Frederico and I’m from Portugal.

I have a second hand 2000 110 TD5 SW, with 180.000 KM, without any historical maintenance records, so I have no idea what problems it could have had.

Some time ago, when I was driving, for a few instants it suddenly lost power.

It happened a second time and this time I was able to see the temperature gauge going, momentarily, to the red.

When I stopped I found out there was, more or less, 1 liter missing from the coolant expansion.

(I don’t know if this quantity was enough to justify the overheating)

After refilling, everything seemed normal but when I stopped there was water leaking from the back of the head - Plug Core 37D2260L.

After replacing and checking the coolant level, I went for a short ride.

At high rotation there was some gagging.

After stopping I took the coolant expansion cap off.

There was a lot pressure inside and the water rose to the opening level.

I don’t know which should be the correct pressure value inside the coolant system, but I tested it for exhaust gas and the result was negative.

(1 video)



I’m not convinced everything is OK, the gagging at high rotation is still there and the coolant system is always with a lot of pressure in.

Can someone help?

Thanks in advanced.

Frederico

The high temp reading and loss of power is not a rare Td5 problem. It is often cured by running a new earth to the ECM platform direct from the battery.

the temp gague flicks to the red and the goes to blue?

the coolant is boiling in the plastic reseviour?

your water pump is not working. either the blades have rusted away or the pump bearing has failed and is not turning so the coolant is not moving as fast as it should be. From the land of the most expensive land rover defenders on planet earth.

Here goes a photo from the water pump.

Achuakh was right, the blades were completely rusted away.

I just hope the overheating didn’t damage the head gasket!

I will keep you informed.

Well, at least you still have 5 blades there.

I had two left. From the land of the most expensive land rover defenders on planet earth. At �125k for a XS 110 csw and you get to own it only for 10yrs! Please find me a good reason to stay on this island.

Looking to the elbow, the antifreeze also wasn’t any good!

Looks like they used caustic soada instead of antifreeze! Shocked
