Just checked on Rad flush and thermostat replacement for my 2004 Montana. Quoted $333.00 & $375.00. Both shops are well known in my area. Thermostat was $16.00, Flush and fill with Dex-Cool was $100.00, The rest was labor.

one issue could be that you need to change your thermostat
I was charged $250.00 !
The thermostat is located on the front of the engine towards the front of the vehicle. You get to it by removing the intake/air filter box/tubing on the driver's side.
It doesn't matter. A thermostat is a non-serviceable item. If it is bad, you replace it. That probably isn't your problem though.
You should check the thermostat and the fuse for the heater.
I have an '04 and my lights are different than yours. However, the wavy lines probably indicate level, so you probably have a low oil indicator demanding that you add a quart. My Montana has two oil warnings: a dripping oil can says low oil pressure. A dripping oil can with a wrench below it means I should completely change the oil.
Should be located at the engine end of the upper radiator hose in removable housing
follow the driver's side rad hose back from the rad. you will find it mounted on the side
The thermostat housing is dome shaped at the end of the radiator top hose on the block, and should be near the water pump which is on the front of the engine. Not looked at a Montana lay out so can't help further.. :)
Could be low coolant, stuck thermostat, bad heater control head (if climate control)
It's belt driven-if that helps. Also, there will be lines into manifold(s) since it's purpose is to provide o2 to burn anything unburned before it gets to tailpipe. That should help you run it down.
Two symptoms of faulty thermostat which would more than likely require replacement of same: (1) engine overheats quickly (2) engine takes too long or doesn't reach normal operating temperature
first drain the coolant at the bottom drivers side rad follow the top rad hose on drivers side to the motor the housing it is clamped to is the thermostat housing remove the air intake tube & throttle body two bolts hold the housing in place remove them slid the hose and housing out when installing be sure the thermostat is seated or you will break the housing
The thermostat is probably stuck in the open position.
You either are very low on coolant or the engine thermostat may be stuck open. Remove the thermostat and check it. These engines have a propensity to blow intake and head gaskets. Look for coolant in the crankcase as well. It will show up as a milky white oil.
there is a Montana city in Montana.
Montana Tech of the University of Montana was created in 1900.
Hannah Montana is a fictional character and doesn't exist. But Amber Montana is related to Quartz Montana!
Yes the engine will run but not like it should. The thermostat is required on modern engines to get the engine to the proper operating temperature and keep it there. This will give you the very best mileage and performance. The optimum running temperature for most cars is 195 degrees Fahrenheit. without a thermostat the engine will take a long time to reach that temperature all the while wasting fuel. Without a thermostat the engine may run at a cooler temperature which is not a good thing contrary to what you might think. Anyone that tells you that your car doesn't need a thermostat has no clue as to what's going on with today's cars! Microprocessors and sensors depend on a certain set of parameters from the manufacturer. Included in this mix is the engine temperature. Remove the thermostat, and you throw the computer system into a tizzy! Install the correct thermostat for your vehicle and leave it in.
The thermostat is blocked by the intake manifold. It's not an easy job and most likely your are trying to fix a temperature gauge the fluctuates. If that's true then you need head gaskets. The 3400 motor is known for them going and the first indications is the temp varying and missing coolant that has not leaked on the ground.
I had this problem with my 2003 Montana, so naturally after checking the coollant, water pump, and serpentine belt, I replaced the thermostat.( not a fun job). This helped for a while, but I still did not get the heat through that winter that I was expecting. The van overheated the following summer, so back to change the thermostat again. ( I had used a failsafe thermostat, which according to one mechanic probably failed early, but might have saved my engine.) Anyhow, he also asked me if I had bled the system after changing the thermostat the first time. I had never heard of bleeding the cooling system, typically something I reserved for brake work. But there are 2 bled screws, one at the top end by the thermostat housing, the other over to the left of the engine. (follow the metal cooling line) These need to be bled to allow proper circulation or you will get air traps and coolant will not flow properly. Hope this helps.
