hello and thanks for tuning in if you're new to the channel please hit the subscribe button
if you're returning thanks it means a lot today we're going to dive into another coolant leak
seems like around the winter time is when coolant leaks starts and summertime is when ac issues
start as always this is a uh 3.6 liter i think wait a second let me find out yeah 3.6 liter
uh dodge fiat you know i think it's a pentastar motor maybe i don't know um we have a
suspected coolant leak and i think it's underneath the intake manifold so we're gonna pull that off
and look today the first thing you got to remove is the plastic cover it just pops right off
and it exposes the manifold the next thing we're going to remove is this entire snorkel here it
requires the removal of that sensor which is the air intake temp sensor that one band clamp
looks like that is broken already and one of the band clamp and that
whole assembly comes off and then we can get down into the intake and see what's going on
okay i forgot to mention there's some evap sensors here it just slides right
off something like a little rubber grommet and the whole thing comes out
all right now we're down to the intake and not sure let me turn on the light
sure you can see it now it's glistening down there there seems to be some coolant leakage down there
we gotta take this entire intake off i think it's the lower intake manifold gaskets so let
me look at things get everything situated get the tools over here
all right once the intake snorkels out of the way there's two 10 millimeter bolts one there and one
back down the other stud remove those there's one two three four five six i think seven
eight millimeter bolts and then you'll be able to remove this top intake plenum
and also make sure you disconnect all the electrical this uh all the electrical connectors
so let's get this thing out of the way okay so the intake manifolds off now we're down to the
lower intake manifold if you wanted to change your spark plugs now would be the time to do so
found the easiest way is probably going to be to take off the spark plug wire
the coil wires on both sides because the harness is attached to the fuel injectors and
the fuel injectors are held down by the fuel rails and all that other stuff so i just want
to lift this up and out of the way to see what's going on down below if you can see all
that coolant down there so we're probably just going to do that we'll disconnect the harness
leave it connected to the rail lead fuel injectors like the fuel rail in and just pull up those
5 16ths or 8 millimeter bolts there let's get that off you can just leave the harness like i said
all connected on there with the fuel wheels you ain't gonna mess with it or nothing
and just hold it back that's all the room you need to get down there and as you can see
the oil cooler is definitely been leaking
as you can see there's oil puddle oil down there that's probably why the oil got low there's some
coolant in there too so about to get all this apart get it pulled out and clean all that out
that crud on the outside of the intake ports go ahead and just vacuum all that out get
everything out you can before you pull this cooler assembly out cooler you have five bolts one two
there's three four and then there's one up in the corner up here so one
one there two three four five back there they're an e an inside torque type socket but a quarter
inch standard socket will do just fine to take them out once you back them out you got to kind
of wiggle this up there's a little o-ring and tube that sit down into the engine block
wiggle that up and then you'll have enough room to free up all these connectors down here
well it's a coolant hose and two electrical connectors one of them are your standard dodge um
two-step plugs where you gotta slide the little connector up and pull it off and then the other
one's just a regular standard plug let's get this thing out forgot to mention you will need to drain
the coolant before you pull this cooler up because this is a coolant and oil cooler chamber so it has
both running in there so just make sure you drain your coolant out to an approved drain pan which i
have down there collecting everything and then you can start pulling off and disconnecting all
your connectors and hose back there we got down to the lower intake valley and got that
oil and coolant cooler out and as you can see it was leaking both oil and coolant in there
so we're going to get this all cleaned out come over and show you exactly what happened
so my knowledges have been prone to fail so if you see the o-rings are all just worn out
and basically it just started leaking all over itself
so i'll have to get a new assembly from dodge and we'll see what happens
and get all this stuff cleaned out in here and we'll see how it actually looks
i just wanted to stop the show how much fluid was actually in there using a fluid extractor
to get it out it's really gross just make sure you clean all that out good as you see
there was a lot of oil and coolant down there i cleaned it out a couple shots of break clean
i gotta wait to see where i can get the part it's probably a dealer only part like i said i
want the most up-to-date one because this was a problem with this motor because this is the
first year they went to this so stay tuned for the install video thanks for watching please subscribe
