Driving home tonight I noticed that the temp gauge was running hotter than usual, and I smelled an electrical plasticy odor. I pulled over, shut the engine off, and raised the hood. I saw smoke coming from the cooling fan motor area and smelled what smelled like plastic burning. The upper radiator hose was also bulging. After letting things cool down, I checked the coolant overflow tank which was full. I tried to turn the fan blade, but it was very difficult and was binding up. The upper hose also was kinda soft where it attaches to the engine. I assume that I need to replace the entire fan assembly and, obviously, the hose. Is that hard to do? Is the Dorman 620-118 or TYC 620950 a better part? Any other thoughts?
