Need Help about temperature of my 300E'89. Almost 110 Celcius if traffic, Is that normal or not ? What I must do ? I already change A/C Condensor and all the ruber pipe. Any suggestion, please ?

 

thermostat, fan switch, flush your radiator...

 

Thanks, mic280. I already changed all you said to me. But still the temperature up. How about Water Pump ? The car only has single big fan. any suggestion again ?

 

When you reach that temperature are you running your a/c or fan in traffic? Water pump is also a possible coz.

 

Yes, I running my a/c in traffic. And slowly going up the temperature to 110 celcius. After traffic and got fresh air, so the temperature slow going down to 90 celcius.
Maybe I must change my water pump. Is it make any big point if I change water pump ?
Regards,

I doubt that the waterpump is the problem. If temperature reduces quickly when the traffics flows again and increases at stop and go traffic the cause of the temp-rise is most probably the fluid coupling driving the main fan. Simple job to replace DIY.
Just open the central allen srew 5 or 6 mm. You need to hold the fan assembly in place to loosen the srew. Insert a 5 mm diameter rod (even better bend it first by 90 degrees 10-15 mm long) in the little slot you find on the circumference of the coupling housing
The test is the following procedure.
Try to push the fan (engine OFF!!!) if it moves itself more than say 90 degrees angle, the coupling needs replacement. The reason is that the fan adjusts the speed through the fluid coupling if the seals are worn the force to tunr the fan reduces to the point that under extreme outside temperatures the radiator is not getting enough air.

 

Thanks bamberger_1.
I'll replace DIY for my fan.
is there any different with the temperature if I change with the double fan ?

 

The double fans on the outside are to cool the condensor for the A/C they run depending on the pressure/temperature of the air condition circuit. Of corse it has to do with the air temperature approaching the engine radiator, but the main radiator fan on the inside is operating with a fluid coupling which increases speed if temperature rises during stop and go traffic or driving in uphill @ low speed. I'm pretty sure you need to replace the coupling and the temperature stabilizes again between 80 and 90 (95) degrees even under stop and go conditions. DIY means Do-It- Yourself.
