225 running a bit warm!!!

The coolant is 50/50 and I added a bottle of water wetter. The coolant looks clean no real reason to think its rusted and mucked up. Maybe I will change the hoses this weekend and backflush the block its a start I guess. In that pic there was a noisy flex fan steel with aluminum blades tossed it and put the solid steel race fan on it!!! Simply for noise reduction!!! Once again thanks guys for helping me troubleshoot this!!!
