How to change engine core plugs on my 2006 trail

You may have to disconnect the carb
Plugs facing the bulkhead may be unreachable without lifting out the engine, so you may have to have the job done at a garage.
Do not cut a hole in the bulkhead. It is load-bearing and, unless you weld a battery and drain the engine block, saving the coolant if you want to reuse it (See how to flush engine radiator).
Catch the coolant in a clean container,
Removing core plugs
With either type of plug, the usual way of removing it is to carefully drive a small screwdriver blade through the middle of the plug and prise it out.
Take care to pull out a cup-type plug straight, or it may jam.
The edges of a cup plug may project far enough for you to pull it out with two pairs of pliers. Grip the edges firmly and pull with an even amount of force on both pairs of pliers. Do not lever against the block - you may damage the plug seating.
Scrape the remains of the old sealant from the hole with a piece of wood.
Replacing a core plug Smear the mating surfaces of both plug and hole with gasket sealant.
Insert a disc-type plug with the domed side outwards. Make sure it rests squarely on the shoulder inside the hole. Tap it in the middle with a flat-headed punch to expand it. It must be a firm fit
For a cup-type plug, find a socket which fits snugly inside the cup. Hold the cup absolutely square and flat against the hole, and drive it home by tapping the socket with a soft-faced hammer.
Do not let the plug get crooked, and leave a little of the rim protruding in case you have to remove the plug later.
There may not be room to swing a hammer. For example, the Leyland 'B'-type enginr has a disc plug just in front of the bulkhead and masked by the engine backplate. But there is a hole in the backplate facing the plug.
Insert the new plug, put a 2 in. (50 mm) bolt through the hole in the backplate, and fit a washer and nut to it on the other side. Screw up the bolt to press the plug firmly home.
You may be able to adapt this method for replacing other awkward plugs.

Does anybody have a video link on how to flush the cooling system on a GM 3.1L SFI OHV 6cyl motor? I need a vid for this particular motor cause mine is still overheating & i have looked everywhere.

flushing a cooling system is the same method as any other motor

do it without the thermostat fitted
or water pump opening

sacrifice an old radiator hose to adapt a garden hose fitting
for radiator flush

air in system fix
your thermostat housing has no air bleed valve
no top radiator cap

old school way
heater on full
run motor till thermostats fully open
burp radiator hoses
wait till water is running up into over flow bottle without bubble
replace cap
turn off heater
correct level in over flow bottle

why still over heating
you fitted everything i would have ... yet still overheat
leaking inlet manifold gaskets
hose clamps loose
cooling fans spinning too slow
thermostatic fan switch faulty
aluminum radiator is a big one
air ..fins bent or some water channels blocked

or possible head gasket leak

How do I change the thermostat on a 2006 Buick lucerne?

follow the top radiator hose to the engine , the thermostat will be housed in a casing that the top hose joins to , the housing will have 2-3 bolts that need to be removed to gain acces to the thermostat, when fitting new thermostat ensure it is fitted the correct way round , take a picture of the old one before removal then you can't go wrong , ensure you have a new gasket to fit as well and make sure the two faces of the housing are completely clean of the old gasket material as otherwise you will get a leak , hope this helps

No heating inside cabin , motor not heating , mybe thermostat open nonstop coment

Thermostat is the place to start. Remove the old one. It should be closed when you remove it. Get a Dodge thermostat because on later model cars they need to warm up in a set time frame or you may get an on going check engine light. It will also be the correct temp vs aftermarket which may not be.

Termostat stuck

If you mean that the temp rises and then falls quickly, you're probably right. If that's the case, you only need to replace the thermostat, which is not too hard to do. Drain enough of the antifreeze to lower the level so you can remove the thermostat without it leaking all over. loosen the housing over the thermostat, remove the old one and use a plastic scraper to remove the old gasket completely. Put the new one in the same direction as the old one, replace the cover but do not over tighten the bolts. Replace the antifreeze and run the car to test for leaks once it gets to normal operating temp. Good luck.

How to change thermostat

The Termostat fit inside the Termostat Housing. It normally links to one of the radiator hoses leading from the engine block or radiator. Depending on the model you have, the termostat housing needs to be opened, the old termostat removed and the new termostat inserted. It's quiet simple. Before closing up, make sure that the both surfaces on the housing are clean and free from dirt and old sealant. If you remove a gasket, then replace with new gasket. If the housing takes a rubber O ring, then it is advisable to replace this.

Good Luck

How do i change the thermostat on a 1991 capri?

You'll need a philips screwdriver, flat screwdriver, and a 12mm open end wrench. Buy a new thermostat and gasket from your local auto parts store. Used the philips screwdriver to loosen the hose clamps from both ends of the air intake. Remove the air intake and set aside so you have room to get to the thermostat housing. Make sure you have a drip pan under the car to catch any spilled coolant. Follow the top radiator hose on the right hand side down to where it connects to the engine. Use the flat head screwdriver to loosen the hose clamp and remove the end of the radiator hose attached to the thermostat housing. You can lift the open end of the hose up and off to the side so it doesn't leak coolant. There is a bolt on the top of the thermostat housing and a nut on the bottom towards the back. Use your 12mm wrench to remove the nut from the bottom of the housing and the bolt from the top. Once you have removed the bolt and the nut, you can remove the thermostat housing. Remove the old thermostat and the old gasket. Clean up the surfaces of the housing making sure there are no remnants of the old gasket. Put the new thermostat in place. Install the new gasket (some have adhesive on them to hold them in place during installation. If yours doesn't, you can use a little bit of grease or gasket adhesive). Reinstall the thermostat housing. Replace the bottom nut and the top bolt. Reattach the radiator hose to the thermostat housing and tighten the hose clamp. Replace the air intake and tighten the hose clamps. Fill your radiator with 50/50 mix of water and anti-freeze. Start the car and turn on the heater. Let it run to clear any air from the system. Later, when the car has had time to cool down, check the coolant level and fill as necessary. Cost: Thermostat $4.99, Gasket $.99. Time invested: about 1 hour.

You will have to cut into the transmission hump until you have enough room to fit your new transmission and get the shift linkage in place. Then you can rebuild around the new setup. It might be easier to get a new hump from a later model car that came with a 350 or 400 transmission and replace your old one with that. Hope this helps.

Thermostat location

The thermostat is in a difficult position. Follow the upper radiator hose and it leads into the block under the throttle body. 
Remove the air filter assembly and you'll c what is the exhaust manifold crossover pipe right in front of the thermostat housing.
 NICE, it gives you very little room to remove the 2 bolts to the housing and once u remove those then you'll find you have the thermostat housing loose but because of that darn exhaust manifold crossover pipe u don't have enough room to take the thermostat housing out to change the stinking thermostat. 
So from what you can see, you have to remove the heat shield which is cased around the exhaust manifold crossover pipe and if you still can't get enough room to remove the thermostat, (which you amy find out)then you'll have to remove the crossover pipe as well just to change the thermostat. 
If you have to remove the crossover pipe then their are 2 bolts on both ends of the pipe leading into the manifolds. But then the tough parts done and once u switch the thermostat over and ATTENTION:remove any old gasket material and put a new gasket in it's place then installation is reverse of removal. 
Good luck and hope this helps,
