NO HEAT!

[huntin5L]

Well it is going to be getting cold here real soon, and im trying to figure out why i have no heat coming out, just cool air. I already replaced the thermostat, which i originally thought was a problem a while back because the heat would take like 10 minutes to kick on while driving so i replaced it. Now i get no heat at all.

yur heater vsv is prolly dead

its a valve that opens to let the coolant flow thru to the heater core.

its a little BOV looking thing above the turbo on the firewall with a hose coming out the bottom and one out the side and a little vacuum line coming out of the top.

is your engine temp right? maybe your blower radiator is cloged

bypass the heater vsv

bypass the heater vsv

I bypassed mine and I can't tell the difference from stock, i.e. heater blows nice and hot, and ac is cold. good job toyota!

my engine temp is right on, im gonna go out there and see what im looking at, thanks for the pic. So you just have to take the hose off where you have the bottom arrow and connect it to the hose where the top arrow is?

 

[huntin5L]

well, i went out there and i pulled the metal rod upward and heat started coming out. So i guess it is safe to say i need a new vsv.

Anyone got one pm me please. Thanks, Bob

That bypass should get you by until you get one.

 

[huntin5L]

you can't have the air on though right with the quick fix?

 

[isnms]

sure you can

 

[huntin5L]

so what is the point of a vsv? lol

 

[huntin5L]

so essentially you can run without it forever

Also, is that what you have to do to hook it up, refer to my post after cwapface to see what im talking about.

If your heater fan runs normally but there is no heat, the vacuum solenoid valve (VSV) probably needs to be replaced. With two exceptions, the VSV is energized anytime the engine is running which allows vacuum to be applied to the hot water valve actuator which in turn opens the heater core hot water valve. If the VSV is burned out, the water valve won't open producing the no heat symptom.

*might find a cheap one on a part out in for sale form.

Yes, hook the two arrow points together

that damn valve is poppycock.
toyota wanted a 180 bucks for that shit.
fuck it.
bypass.

It prevents hot water from flowing into the heater core when you are trying to use AC. Think of it as an AC booster.

[isnms]
