Follow the upper radiator hose to the engine, the T-Stat under the housing at the engine end of the hose, it may be down under on the side of the engine block as are most engines with reverse flow cooling system's

Is it an easy job to change the thermostat on a Mitsubishi Express Van 2004. I was told it was at the end of the top radiator hose. My sons car has broken down are there any tricks I should know.

Loosen the upper radiator hose. This is the hose that connects to top of the radiator to the engine. Loosen the hose on the end that connects to the engine by using a flat-tip screwdriver to loosen the circular clamp.

  • Remove the hose. Pull the upper radiator hose off the end that connects to the engine. Have a drain pan underneath the hose to catch any coolant that remains in the hose.

  • Loosen the thermostat housing. Use your ratchet and socket set to loosen the bolts that hold your Mitsubishi's thermostat housing in place. The number of bolts and their locations vary based on your Mitsubishi model

    How to install a thermostat

    I found this for you

    there is a hose that runs from the right side of the radiator to the engine right by the air intake, remove that hose, it leads to the housing for the thermostat, there are 2 bolts that you have to remove on the housing itself, one on top and one on bottom, once thats done you can access the thermostat

    and this

    Drain the radiator in a container. Remove the engine end of the top radiator hose. The housing has 2 bolts that you remove. Remove the thermostat and clean the surfaces and reinstall the thermostat. Reinstall the hose and add coolant.

    Where is the thermostat on a 2004 Mitsubishi montero limited

    Right under the hose connection coming from the radiator to the engine, at the engine side. That upper radiator hose connects to the engine thru the thermostat housing. Usually 2 bolts hold it onto engine and the hose connects to it.

    Hello, I have a 95 Tacoma 4x4, 2.7, 67k miles. I'm having problems with no heat and want to replace the thermostat. I've searched the internet wanting to be sure of where it's...

    It probably is at that bottom hose connection. I just replaced a water pump and t-stat on a 2004 Mazda van with a ford v-6 engine (3.0L), and the thermostat housing and thermostat was on the bottom hose from the radiator. This one had no radiator cap, just the recovery tank with a pressurized cap fitting. I think they call it a degas bottle system-something like that, might be relevant or not. But anyway, if you have the housing on the lower hose, don't be surprised if that is where the thermostat goes, some coolant systems are like that.

    Where is the thermostat on a pontiac montana

    Geez, don't make it easy on me! Duh, it would help if you told us the year of your Montana. Based on the absolute lack of info you've given, I can only tell you this. Follow the upper radiator hose back to the engine. The aluminum housing that attaches to the upper radiator hose [at the engine] covers the thermostat.
    Drain the coolant from the radiator. Disconnect the upper radiator hose from the thermostat housing. Unbolt the housing from the intake manifold [2 bolts] & you will find the thermostat.

    Change the thermostat in the galant.

    1. Raise the front of your Mitsubishi Galant with a jack and lower onto jack stands, or use wheel ramps. Disconnect the negative cable from the battery. Drain the coolant into a suitable container by opening the drain plug on the bottom of the radiator.
    2. Step 2 Follow the upper radiator hose to where it meets the engine at the thermostat housing. Loosen the clamp at the engine end of the radiator hose and pull the hose off the thermostat housing.
    3. Step 3 Remove the two bolts on the thermostat housing cover and pull off the cover. Note the position of the old thermostat and remove it from the thermostat housing. Place a rag in the thermostat housing and scrape any gasket residue from the inside of the thermostat housing cover.
    4. Step 4 Take out the rag and insert the new thermostat in the same position as the old one, with the spring-side facing into the engine. Install the new gasket or o-ring, depending on the type of thermostat you are installing. Note that most late 1980s and early 1990s Galant models use a thermostat gasket.
    5. Step 5 Replace the thermostat housing cover and tighten the bolts. Re-attach the radiator hose and tighten the clamp. Fill the radiator with new coolant, or use the coolant drained from your Galant earlier if it's relatively new and clean.
    6. Step 6 Start your Mitsubishi Galant and run with the heater on high until it reaches operating temperature. Make sure the heater is blowing warm air to ensure the thermostat is working properly. Check for leaks and tighten the radiator hose clamps if you detect any.
