Engine Cooling problem
1994 GMC Sonoma 6 cyl Four Wheel Drive Automatic 200K+ miles

I recently replaced a leaking hose and thermostat on my truck. It was running at 210 before repairs and I'm still up in that range after. My wife's Blazer has the same engine I do but runs no where near as hot. There is no sign the water pump is going out(bearing squeal or leaking from pump). Is there something I'm missing? Should I just pull the pump and replace? Thanks for any info.
