rev up your engines, customers got a Honda core it's overheating then the air
conditioning stopped working so the first thing you have to fix is the
overheating if your cooling system gets too hot on any modern car the computer
will turn the air conditioner off it won't let you run the air conditioner
and further overheat the car so first we're gonna figure out why this baby is
overheating so I'll check the coolant level, okay it's low on coolant so
it's leaking somewhere and in this case I don't even have to use a pressure
tester because when we look around we look back here what do we see this is
the heater core valve you can see it's dripping coolant so we're gonna replace
that first there's a brand new or it's pretty simple just has a valve that
opens and closes the hot water goes through when it's closed nothing happens
when it's open hot air goes into the heater and gives you heat and in this case it's
leaking where they always do there's a seal here where the valve is and that's
dripping so we replace the whole thing it's a pretty simple job the rod here
the cable just snaps right off you take two screws off in the hoses you just
remove these two little screws on the top and no sembly slides off
then you grab little crimp pliers and make sure the hose is nice and loose now
we can pick the valve up and you can see it better just grab the other side we's
that side down and then take it off oh you got away let there then you get your
new heater control go sticking out here waggle it then grab the clamp put it
back in place now it won't leak no it's cars these days don't use the old screw
clamps when you screw to man do you squeeze clamps because the squeeze is
tensile steel so it's already squeezing so if the hose wears gets thinner it'll
continue to squeeze and it won't leak where an old fashioned screw one you
screw it tight but then when it shrunk it wouldn't get itself any tighter that's
why they use them they can be a pain but they actually work better now once you
get the hoses on you just get the little metal rod and it pushes over the valve
see that will open and close then first fill up
cooling the radiator and start the car up
and turn the heater on full blast there it comes
we went to run at 10-15 minutes watch the temperature gauge we want the
thermostat to open so we can burp all the air out of the system and only have
cool now I have to let it run fill up the rest of the coolant it's not
overheating anymore so let's check the AC turn the AC on we'll put it on max AC
rev it up a little, with the AC on full blast the cooling fan should be running
the neither of them is warning is it something wrong
electronically get a little tester out and we'll check the fuses, the fuse box is
here so we'll start checking it well unfortunately it's got power on both
sides of all the fuses so none of the fuses are wrong well unfortunately the
air-conditioning not working of nothing to do with the overheating because as
you check the dash, it's been running for half an hour now and you can see the
temperature gauge isn't even half way so it's not overheating but try as we may
turning us on the AC on the AC just will not turn the compressor or the fans on
so walk up a set of AC gauges to see if it's low on refrigerant or maybe empty
follow the hose will be a gauge that says zero pressure so it's got no
refrigerant in it and since the customer has limited funds he okayed me to fix
the overheating which I did I know how fire wants to go with this it just
bought this car used this kind of an in-between car and when the refrigerant
is all leaked out with zero there's a leak somewhere knowing these Honda's
it's never cheap it's often the compressor so I'll wait on that one to
see what he wants me to do odds are he told me he could stand the
heat cuz he's from New Orleans all here all the windows down, the car will run better
without an air conditioner does strain the engine alone, so now you know how to
fix an overheating car and at least how to figure out why your air conditioning
is not working even if you're not going to go through the trouble of actually
fixing it cuz it might cost too much, so if you never want to miss another one
