Engine Overheat Help - R171
Few days ago i had coolant indicator pop up, thought was antifreeze low added more, nothing happens then in few more days red light saying stop engine shows up. temp shows about 120C.
I started observing temps and looks like when im driving temps are ok ~80C, but if i get stuck in traffic it goes up and up and up
So my guess its either thermostat or fan. My normal guess would be thermostat which is normal to replace at least once in lifetime of the car (i got about 70k miles) however when i did fan actuation 50 and 100% spin about same speed visually. and fan makes some notice that does not sound correct to me. I found some broken plastic on fan so it was out of balance so i can possibly say there may be something wrong with fan too.
Any thoughts on this?
How can i test fan efficiency and thermostat?
Another question is that when i looked up fan cost its like $800 way toooooo much for that part. C63 i bought for $70
So does any one know cross reference parts for fan? Based on photos looks like other V8 like CLK500 has same fan but it cost $150-200 which is more reasonable.
