DODGE NEON ENGINE COOLING

Engine Cooling Problem 2000 Dodge Neon 4 Cyl Automatic 60,000 Miles I Am Having To Replace The Water Pump On My 2000 Dodge Neon....

When I Turn My Air On My Car Bogs Down Then It Blows Out Hot Air. Could A Bad Water Pump Cause This? I've Already Tinkered With The Freon...

If I Have To Have A Water Pump Replaced Does The Engine Need To Be Removed
