Evening, first of all, I wanted to say at this point what a brilliant forum this is. I have already solved many problems with my Essie thanks to the forum. Unfortunately, I am currently faced with a mystery. I have been driving a 1997 Ford Escort (GAL) 1.4 L, 75 Ps. He now has about 145,000 Km. And I have a big cooling problem since a longer tour from Kassel to Koblenz. And indeed, the display rises within a very short time from the O from NORMAL to the L od he even went to the red area. Unfortunately he doesn’t always do that. He was now 3 days in the workshop but nothing could be found (because he didn’t do it with my mechanics of trust). Normal is with my Essie actually the temperature indicator no longer as to the R. Normally…. Today I drove about 60 km and he did it again that the display suddenly rose. In the workshop he got the following new. new coolant, complete Ö change air filter change I really don’t know any more. However, I need the car professionally i.e. need it quickly again….. I hope you can help me P.S. If you need some more data, just let me know. Thank you very much already in advance. LG Casi
