Rev up your engines!
It's time for the Scotty Kilmer Channel, if your car's air conditioning isn't
blowing too cold, you might need a new expansion valve, so today I'm going to
show you how to replace an expansion valve on a Toyota Camry, the first thing
you have to do is hook up your gauges and remove the refrigerant that's
already in the system, now unless the system is already empty,
you need a recycling recovery machine to do this, so you might pay a mechanic to
do that for you, then once the refrigerant is out, you have to remove
the two lines going into the dash, and they're hiding right down here in this
Toyota, these two bolts have to be taken off, just take a wrench on them and lose
them off, then you have to take the glovebox out, to access the evaporator
core where the expansion valve is bolted in, just remove the screws that hold the
glovebox in place on the top, and on the bottom, and then the glovebox just pops
out,
first the door part, then the inner liner comes out, there's the blower motor which
you have to move out of the way to get to the evaporator, so find all the bolts
that hold it in place and take them off, then just grab it, pull it out of the way,
there's the evaporator there, we have to slide it out to get to the expansion
valve, then when you slide the evaporator out of this case, here's the expansion
valve right here, then you get a five millimeter socket and put it on the
expansion valve bolt and take it off, then once you remove the two bolts the
expansion valve just comes right off, now you'll notice that there is O-rings inside,
right in here there's O-rings, you need to put a little air conditioning oil on
them so they seal good, so just get a little air conditioning oil and
pour it in a little cap, and then drip some on each O-ring and spread it with
your fingers, then after lubricating the o-rings, bolt
the expansion valve back onto the evaporator, then slide the evaporator back
into its case, and then both the two hoses back on under the hood, bolt the
lines on nice and tight, then start evacuating the AC system with
vacuum pump, you want to run the vacuum pump for about an hour to get all the
moisture out, and that will give you plenty of time to put the rest of the dash
together, so while that pump is running, put the blower assembly back up and bolt
it in, and bolt it back into place, and don't forget to put the glovebox back in,
then once you put it all back together again,
turn off vacuum pump and fill it up with the correct amount of refrigerant,
the car even tells you how much refrigerant to put in, point nine
kilograms, so open the valves fill it up,
and now it's full, so if your car's air conditioning isn't blowing cold because
the expansion valve is stinking, now you know how to replace it yourself and
remember if you've got any car questions just visit Scotty kilmer.com and I'll
answer them as soon as I get back from this ride!
