1989 Mercedes Benz 260e 6 cyl Two Wheel Drive Automatic 95000 miles
1. How to reduce the knocking caused by heat?
2. How to reduce the overall engine temperature that reaches 95c, (already checked thermostat, radiator and fans).
3. How to reduce fuel consumption (already replaced fuel distributer and nozzle injectors), the economy meter in the dashboard indicates almost to the half with the engine idle and the tachometer indicates 5500 rpm only.
4. Can I fit a 10pa20c a/c compressor in it. Or is it gonna be an overload to the a/c system?
