Bundys Garage, Bundy here
Today I wanted to do an update video on the heat soak
problem. I know there is a lot of confusion about there out
there in a lot of forums that says it has to do with fuel
vaporizing in the fuel rails and I have to disagree with that
just do to the fact that you've had your car for over seven
(7) eight (8) nine (9) years and it's just happening now
if this was a problem from the get go it would of happened
from day one (1) if you actually truly think about it so
something has changed inside the vehicle.
The one thing that I know that actually worked on
two (2) vehicles that I've worked on is this sensor
right there
The engine coolant temperature sensor. It's not going
to throw a code so it's about thirty (30) dollars from
O'Reilly.
What you need to do is just replace it but one thing I
wanted to suggest to everybody taht they try to do is
There is a clip on the backside
So get that out of the way
19mm sensor, so just brake that loose
If you can I had to
I might have to get a wrench a socket I mean
I took a 19mm wrench from Home Depot and
cut it in half as you can see right there.
Because on the Acura TL I was working on there was
no room to get this in and I didn't want to take
the plenum off and everything else so I tried, I snuck
it out basically.
But on this one I'm gonna have to get a 19mm socket
and brake it loose that way so let me grab one of those
and I'm going to show you something else.
I have a 19mm socket here 3/8 drop that down there
go ahead bring this down
and break it loose
ok once you take this out and replace it
what you want to do is your gonna wanna
go ahead and take some coolant green engine coolant
cause that's what these Honda Acura J Series V6
engines take and fill it up fill it all the way to the top
where it's almost spilling out
and if it spills out a little bit no big deal cause what I have
found happens on these engines
Is the fact that customer parked at work and then came
back out and it was hard to start and it was a very
specific angle that it was at when it happened
so what you want to do is fill this up.
If it spills out a little bit no big deal but you want to make
sure that there is no air pockets in this system right here
and as I was saying about the person who only had this
happen at work at a very specific angle
is the fact that if air is stuck in here
then it's going to leave the sensor
naked or not submerged into the coolant and your going to
get a false reading and thats another reason why
this is happening to you.
So it's not a heat soak problem on the Honda or Acura's
it's it's a coolant temperature sensor problem.
Just make sure that when you do replace this
fill it up with coolant before you install the sensor
Hopefully this will help you guys
in fixing this very frustrating problem that
that only happens every once in awhile
it actually what happens is you'll start noticing it
and it might happen once a year, then it happens twice
a year, then it starts happening three times in six months
and then it will start happening six times in one month
it just gets progressively worse and worse and worse.
When you replace this engine coolant temperature
sensor go ahead and fill up the
fill up the sensor hole with
coolant
just top it off
if it spills out not a big deal you can use water
but yeah
it will just get progressively worse as time passes
and it's not a heat soak problem and it's not a it's not a
vapor a fuel vapor locking problem
I know guys are talking about that inside the rails inside
the fuel rails but if it was it would of already happened
from day one it does not matter if it's summer gas or
winter gas it just doesn't vapor lock cars nowadays
specifically on Honda and Acura they are not going to
vapor lock on you that's in carbureted old style cars
this system is tuned far enough and Honda knows
exactly what it's doing to not let that happen
So like I said when you replace the engine coolant
temperature sensor go ahead
top off the green coolant here before you replace it
making sure that that the sensor is actually submerged
and that there is no air pockets in there it's best if you do
this cold another thing you could do if you don't want to
take the intake off like I have done here
is you could actually be very careful when you do it
and use a rag but you could actually when the vehicle
when the engine is warm or hot you could actually
crack this and then let put a rag over this so you don't
burn yourself but crack it while it's warm and coolant will
start to come out
and that way you know there's no air locked up in this
section of the housing
