GMC SIERRA COOLING SYSTEM PROBLEM

1999 GMC Sierra • 64,000 miles

Truck started to heat up has 4.8 v 8 replaced t-stat & housing stays at 195 to 200 degrees now but notice that the lower rad. Hose doesn't get hot even when up to temp. Could there be air trapped in cooling system

195--200degrees F is not overheating. If you think the radiator is clogged, flush it.
