Why would your 2000 Pontiac Montana be smoking and dripping water out the tailpipe after replaceing the thermostat and temp sensor?
small amounts of water coming from the muffler is normal but if its antifreeze its not
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.
Is the thermostat housing where the upper hose meets block because it looks impossible to change without removing the throttle body and exhaust manifold on a 2004 Pontiac Montana?
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 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…
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…
If you are referring to the heat output in the cabin of the vehicle, you may need to install a winter thermostat. The factory installed thermostat may not allow the engine to get warm enough. This used to be common in older vehicles and was required in cold climates like Edmonton, AB Canada where the mercury drops below -40c (-40f) in the winter.
Begin by draining the coolant. Next, you have to remove the exhaust crossover pipe that runs around the rear of the engine, just over the transmission. This will require tilting the engine forward so you can reach the bolts on the rear manifold. Remove the upper radiator hose from the thermostat housing and then remove the bolts. The thermostat is in the recess in the intake manifold. Reverse the process to re-assemble. This little job…
The coolant temp sensor is located on the manifold, just to the left of the thermostat housing on the right side of the engine compartment. They are both located just under the air intake tube that attaches to the throttle body, and it has a small 2 wire connector attached to it. You can follow the upper radiator hose from the radiator to the thermostat housing to locate them. Good luck.
