I was reading about the Pump on the web and I stumble upon this :

This Thermal Switch operates easily. Normally it functions as a closed circuit but when your EAS Compressor runs too hot it will switch off at about 110°C (+/- 5°C). When the pump-temperature goes down again and comes near the 80°C it will allow the pump to run again.

Is that correct?

Thanks wammer but my question was more like : Can the pump itself can goes up to such temperatures?

My pump is often (read always) very hot and I cannot leave my fingers on it more than a few seconds before screaming like a little girl!!!! After a 30 minute or 1h ride in town.

The LR stated maximum running temperature of the compressor is 120C, if you compressor is always that hot either it's knackered and struggling to make pressure or it's feeding a leak.

Thanks Datatek, but we already ruled out a leak (Remove Relay) and no drop. And this as well : http://www.landyzone.co.uk/lz/f10/understanding-logic-behind-eas-234210.html

The Pump is only 2 year old. Also it does not always run, I drove it on the highway and could not hear it even it traffic Jam for a long while. But in the City it will often run at stops (Red light) and turn of when the car is moving.

That does not rule out a leak on the storage side

The tank... Ok then let's investigate this. Now what are the usual suspects there? O-rings? Lines going to the tank? Tank itself?
