My 1998 chevrolet malibu 3.1 v6 replace hoses and still overheats and coolant check for leaks and no leaks.

When it is "overheating" feel the upper and lower hoses. If one hose is hot and one is a lot cooler than you have no flow through the radiator. Most likely cause for this is the thermostat.

The thermostat is located behind the housing that bolts to the drivers side of the intake manifold that the upper hose is attached to. It is not the easiest job in the world to replace but it can be done.

Thermostat housing leaking

Remove and replace gasket. You can also use silacone. If it is the housing itself u will have to replace the housing or fix with JB weld. Hope this helps.

My 2004 malibu does not blow hot air when in the heating position. the blower works and only blows cold air.thermostat seems fine.

What makes you think the thermostat is fine? First thing I would check is the level of your antifreeze to see if it's up to the correct level. If it is then thermostat is my next culprit and if it is in fact OK then it might be the water pump or plugged up heater core.
