I have a Mecerdes benz C270 cdi, 2002 model. when driving 120km per hour it start overheating but when driving les than that, the temp stays normal.

Hi hope this helps. ..cheers

I had got its manual
from online store www.reliable-store.com Here's the site link I am sure they will help you

sounds like something in radio is overheating

top up with COOLANT and drive around for a short distance not to far from home and watch the temp gauge and see how the engine drives if temp gauge goes into red stop wait for engine to cool at least an hour then carefully remove coolant cap and check if there is any coolant loss, if temp gauge stays at normal you may be lucky

remove thermostat with cold engine assembly again check the belt fit new radiator cup blead your sistem and drive 1/2 hur ef stil over heating you have radiator blockige.

This is normal, the glow plugs are building heat in the cylinders to help ignite the diesel. They should cycle off and on until the engine warms up.

e 270cdi 2002 sometimes has low power,sometimes works normal.what is the problem?

you might need a new thermostat

• you need a Brake safety switch replaced.This is located behind you brake pedal.it's a common problem. The warning lights will reset after a few engine starts.

Scan the computer with a STAR Diagnostics system, any Euro mechanic should be able to do it for you.

Temperature showing -38c will be the ambient temp sensor. Only a couple of dollars normally and normally installs in the front bumper somewhere, easy to do it yourself.
