In this video, we're gonna be going over the top five problems that we have found with
this first-generation Buick Enclave.
I just want to emphasize there's nothing wrong with this car.
Every car has their problems, these are just the top five that we have found.
Number one, timing chains.
Now, the timing chains on this vehicle are located in the front of the motor.
They're internal to the engine, and they basically connect the top part of the motor to the bottom
part of the motor.
Over time, they will stretch and you may not notice any drivability issues other than the
check engine light coming on.
And what those codes are gonna say is basically the engine isn't timed properly.
Whatever adjustments the computer's trying to make aren't going to be able to compensate
for the stretch of the time chain.
To help prevent this from happening prematurely, make sure you change your oil regularly and
make sure it's always topped off.
Number two, ignition coils.
So, because this is a V6 engine, you have three coils on this side and then three coils
on the backside that you can't see.
When you replace these coils, because of the location of this one, you can't get that out.
So you're gonna have to remove the intake to actually do that.
So when you take that off, you want to replace the intake gasket as well.
Some of the symptoms with bad coils you'll notice is a check engine light that's flashing
and the engine will be most likely running rough.
And one of the things that happens is the coils actually get really hot and you can
actually see on the coil where it's actually burnt.
And if you smelled it, it would smell a little burnt.
And when you're replacing those, if you had a problem, it's always a good idea to do the
plugs as well.
Number three, water pump.
Now, the water pump will start leaking.
You should notice some coolant on the ground in the front of the engine, so more towards
the passenger side of the vehicle.
Hopefully, you notice that before your engine starts overheating.
If you're doing this job at home, you can do it from above.
You just have to disconnect the battery and take some of the components out of the way,
take the mount out of the way.
And it's actually not that hard to get to, just a lot of components in your way.
Now, you can access the pump from underneath right here.
It's just not too easy if you were gonna do this on the ground.
Take the belt off, take those bolts off the pulley.
And it's a little bit tight, and then you might even have to pry the motor over a little
bit, but you can do it.
Number four, the power steering pump.
Now the pump is located right here and that's what's gonna give you the power steering assist.
When you turn the wheel back and forth, you want fluid pressure to go into the steering
rack.
And if you find that the steering wheel is binding up, there could either be a lack of
fluid or it could be the pump starting to wear out.
So you want to visually look at the pump and see if it's leaking.
If it's leaking, it needs to be replaced.
Now, if the fluid level is low, there's a couple other areas you can check.
The power steering gear itself could be leaking.
It looks like this one's leaking.
There's fluid leaking into the boots right there.
Also, this hose that's on the backside of the motor right here, it goes from the pump
side all the way across and then into the steering rack here.
That's the pressure side.
So you might see it dripping right from where that attaches to the motor or dripping in
this area here.
Then, in that case, that's got to be replaced.
So check the front of the pump to see if there's any fluid.
It looks like out of the front seal, there is fluid coming out.
So in that case, this pump would need to be replaced.
If you're looking for where the power steering reservoir is so you can check the fluid level,
it's actually under this cover.
Take this oil cap off, grab the cover, pull it up.
It's right there.
You can grab the cover, twist it to the left and then wipe the fluid off, and then recheck
it.
There we go.
There's a min-max line.
You want it somewhere in between.
Number five, heating and air conditioning temperature door actuators.
A lot of vehicles have dual-zone climate control.
So if the passenger's cold, they can turn up the heat, and if the driver's hot, they
can turn on the air conditioning.
Now, once in a while you may notice that if they're both set to a certain setting, that
one zone's hot and one zone's cold, or it's always hot out of the passenger side.
No matter what you do, it's stuck there.
In that case, most of the time, it's that actuator that actually changes the position
of the door so it will make it hot or cold.
It's just gotta be replaced.
Now, where the actuators are on the passenger side, there's an actuator way up here.
You have to take some panels out of the way.
And the one for the driver's side is above the gas pedal on the right.
So those are the top five problems that we found on this Buick Enclave.
