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

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.

You should check the thermostat and the fuse for the heater.

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.

Should be located at the engine end of the upper radiator hose in removable housing

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.

follow the driver's side rad hose back from the rad. you will find it mounted on the side

Could be low coolant, stuck thermostat, bad heater control head (if climate control)

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.. :)

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

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.

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

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!

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.

Montana Tech is located in the state of Montana.

Montana does not have an official rock or stone. Sapphire and Montana agate are official gemstones for Montana.
