Dear Vintage - Opel friends,
I'm pleased to be able to offer you the following article:
Beru coolant temperature sensor 'blue' L & LE-Jetronic & Motronic
This sensor sits up on the head of the thermostat cover and, as it ages, gives incorrect valueswith increasing frequency to the electronic control unit of the fuel-injection system! Generally the engine rewards the exchange of this temperature-dependent resistance with an improved engine run and less fuel consumption.
All 2.0E, 2.5E, 3.0E as well as various Motronic cih-engines are fitted out with this part. ATTENTION: Your sensor also needs to have a blue plug, if this is black, for example, then this sensor is not compatible!
