The hose is only needed to pump out hot air while using the AC features and not needed at all for heater functions.

How do you winterize a 2015 chaparral 390 QSMB?

At the back of the water heater ( unless you have a bypass outside in the compartment with the sewer and city water )there should be 3 valves, the one on the vertical line leave open and close the 2 leading into the heater. That will bypass your heater. Then connect your antifreeze hose (garden hose ) to the city connect. Using a water pump ( just like the one in your unit) have someone plug it in ( suction hose in the antifreeze of course) open one at a time each faucet hot and then cold till you see the pink running. It may take a couple gallons so get a 5 gal jug. Don't forget to remove the water filter under the sink.

How to diagnose ALL vehicle NO heat problems

It is winter and you jump in your car start it up and turn the heater blower fan on.
You sit and wait...and wait.... NO HEAT !
Here are a few easy steps to help diagnose the problem:

1) After vehicle is completely warmed up, open your vehicles hood.

2) Grab a pair of gloves. Put them on, now put your hand with your glove on, on the TOP radiator hose. ( The top black radiator hose is the largest hose on the top of the radiator inlet running to the thermostat housing, in most vehicles)

3) Be careful NOT to touch ANY part of the engines cooling fan(s). Is the radiator hose HOT or COLD to the touch ?

If the hose is cold the easiest repair is to replace the thermostat. The thermostat helps regulate the engine temperature keeping it approximately 195 degrees Fahrenheit, and helps supply hot coolant to run through your vehicles heater core to keep you warm in the winter.

How do I disconnect heater for 2004 Toyota Highlander?

bypass the heater core. 2 small hoses run from the firewall to different locations on the engine (one should be the thermostat housing. dissconnect one hose from fire wall end, and reconnect it to where the opposite end of the other hose is located, creating a loop that does not include the heater core. The remaining hose (one end still attached to the heater core at the fire wall) should be connected to the opposite connection at the fire wall so it can be re-engaged next winter.

Actual problem seems to be the heat damper valve, which restricts water flow into the heater core, easiest fix is reattach the actuating cable to the valve arm (if this was detached) most costly is replace valve assemble/heater core assembly....

My antifreeze is leaking and I am trying to find the leak. It also leaks from inside of my truck on the passenger side where their feet are.

Your heater core is leaking. Replacement of this part is a big job and should be done by a professional.

Can i bypass the heater core?

Yes. You would need to join both hoses from the firewall into a loop to circulate the water back into the engine. You will need to measure the hose sizes and make a connector. You will need to clamp the hoses to the connector.

If you use copper tubing, you should flare the ends to insure a good seal.

Pipe that comes out of thermostat and goes into firewall is leaking coolent in '02 Impala, 3.4 liter? Whats this pipe? and can i use pipe dope or something?

This sounds like it goes to your heater core. It is like a small radiator inside your car that circulates hot engine coolant to give you heat when you turn on your heater. You should have rubber hoses that connect the heater core to the thermostat housing. Look closely as to what is leaking, the rubber hose, or the thermostat housing, and try to "snug" up the hose clamp if you can. Some time the thermostat housings corrode and leak. You will need to replace it if that's the case.(Keep in mide that some vehicles use clamps that are spring type, and you can't snug them up)
