Hi guys, I got a replacement thermostat a few days ago. I was going to have my mechanic install it this weekend, but he's not available. From researching a bit, I understand this is a relatively short and easy job. Perhaps it will be suitable to serve as my very first DIY? I wasn't able to find a guide or materials specifically for the W203 C200 CDI (OM646), so I was hoping one of you could point me in the right direction to existing instructions/materials, or anything that will be enough to walk me through this first DIY. Thanks a lot in advance to anyone that can provide assistance.
