this is my 2015 dodge grand caravan stx 3.2 l v6 and in this video i'll be showing you how
to replace a thermostat on a dodge caravan fifth generation or chrysler town and country hey guys
welcome to daddicated my name is andy i like to fix stuff build stuff and remodel stuff on this

usually if your thermostat goes bad your check engine light goes on and you should get a p0128
thermostat rationality test error i took my grand caravan to autozone and this is the report that
they gave me and told me that replacing the thermostat usually does the trick so here we go
step one buy a replacement thermostat on amazon by clicking the link in the description below
or you can pick one up at your local auto store it's also a good idea to buy
a gallon of coolant while you're at it step two you will need a 13 millimeter socket head
in order to remove this nut on the power steering container then unclip these three clips that hold
the air intake manifold cover lift up the power steering container and move it out of the way next
lift up the air intake cover and remove the air filter it's a good idea to get a new filter while
you're doing this step 3 remove the bottom of the air filter manifold you will need to give
a nice jerk and pulling it up since there will be three pins that are holding it down this way
you'll have a better access to the thermostat from the side it's a good idea to use some sort of a
stick to hold the top of the manifold out of your way while you're working on this step four before
removing these two nuts and this pipe clamp i have to remove this plastic piece under the car so that
the coolant has somewhere to leak out to i'll be using my clip removal tool and a 10 millimeter
socket to remove this plastic cover the cover is held by two 10 millimeter nuts one on the far side
and one on the near side there's also two clips one in the front and one in the middle that you
will need to remove once the clips and the nuts are removed you should be able to just pull it off
like this here's what it looks like step 5 use a pan or a bucket and place it under the car in the
same location where the thermostat is once you remove the thermostat it will leak some coolant
on the floor so i took some old towels and laid them out as well in addition it's a good idea to
wear some gloves before removing the thermostat step six take a 10 millimeter socket with a short
extension and remove these two nuts i ended up using a swivel head joint since i didn't have
short enough extension but this worked out just fine once the nuts are removed move the thermostat
back and forth and gently pull it towards you you will see the coolant will start pouring out
right away as soon as you do this here's what the mess looks like under the car and here's how much
coolant i managed to save from my driveway step seven use some vice grips or other means to remove
the clamp on the hose no you will struggle a little bit until you move the clamp far down
enough and then this thermostat can be removed freely from the hose once you remove the old
thermostat out of the hose install the new one and place the clamp back while it's in the vise grip
next place the new thermostat back in place insert the old bolts and tighten them as necessary
step 8. install the bottom of the air intake manifold you will need to align this hole and
these pins with the matching mates on the frame it takes a little bit of finesse but you will feel it
drop down once you get it back into place next place the power steering back on the
bolt and insert the air intake filter use the three latches to secure the top back on
place the nut back on to secure the power steering container step nine install the plastic cover
back on the bottom with the two bolts and the two clips step 10 find this cooling cap and remove it
you can use a regular funnel for this or you can buy this nice one on amazon
which will make it a breeze to fill in the coolant my buddy told me about it
while i was already in the middle of this process but i strongly recommend using
it i'll have links in the description below slowly begin to fill the radiator
with a coolant all the way to the top be careful not to overflow and make a big mess
when you fill the system with some coolant you will need to turn this knob with a phillips head
screwdriver to bleed out some air when you turn it you will hear and see the bubbles coming out
along with the coolant you will need to do this on and off multiple times while filling the system
all the way up next fill the coolant reservoir to the max line which is located right here
once all the coolant is filled start the car and let it run for five to ten minutes
again use the phillips head screwdriver and bleed the air
out again that's it hit that like button and don't forget to subscribe
