my 95 s-10 blazer 4wd is overheating when i go slow but cools off the faster i go. i have an electric fan because mine sheared off and ive had it for over a year w/o probs my coolant is fine i recently flushed it because i thought that might be the prob and the pump is 2 years old. what am i missing?

 

Have you checked the functionality of the electric fan?..Like the F word don't ya? Probably wearing down over time...ie doesn't run as well as it used to. How much damage to the failure of your fan do? I'd suggest replacing it.
