I turn on my heat and the fan starts up but it take a while to get warm something its warms up hot then other time its Luke warm air I have change the water pump which is not even a year old. some time I smell a smell inside my car but no leak inside my car where would I tell if its leaking out side
Places I would check would be thermostat and heater core. To check the thermostat, take it out of the truck and bring it in the house, get a pot of water boiling on your stove. Once the water gets to a boil ( or close to boil 190 deg F ) put the thermostat into the water and if it is working you will see it spring open. The heater core I would recommend changing it if your smelling coolant in the truck. Even if your not seeing a leak inside it could still be leaking. Check eBay and Amazon for pricing if you can afford to wait 7-10 days for shipping. Hope this helps, and happy wrenching
It's not a pump problem. Check the thermostat and coolant flow through the heater itself.

Is the engine fan staying engaged? If so this will not allow you to build addequate engine temp. especially while driving.

a bad heater core will just leak. it could leak alot. do you ever smell antifreeze? check the coolant level. it can get pretty low before it will overheat. the thermostat should be ok but there could be corrosion. when you had the water pump replaced was the cooling system flushed? 2001, its probably due for a flush. what coolant does it take? (green or orange)

The first thing I would check would be....be sure that the compressor is definitely coming on, if not check the connections. If the compressor is running physically touch the large line coming from the compressor, this should be cold to the touch. if that's the case your problem is going to be inside under the dash on the temperature controlled door. This door is controlled by a vacuum operated solenoid. Check the vacuum line that feeds this solenoid for leaks or vacuum in general. If you have vacuum but the valve is still not operating, replace the valve and enjoy your a/c. Hope this helps, good luck!
