HEATER VSV(VACCUM SALONID VALVE)

WHITETURBO · 01-31-2005, 12:01 PM

My heater did not work. I tracked it down to a bad vsv ( part # 084600-8980). This selonided
opens the valve that lets the hot water runs through the heater core. I bypassed the valve (it is always open now) and the heat works - Can this heart anything? Also, does any body have a spare or can tell me where I can buy one for a reasonable price.

well i wouldn't expect it would hurt anything... i think i have it bypassed as well and no probs....
i'm sure someone else has one somewhere

it does not hurt if you just bypass it
i have heard that the only purpose for this valve is that it shuts off fluid to the heater core only when the a/c is on high
im not totally shure maybe someone else can correct me but i have mine removed and it works great

i have mine bypasssed as well and it hasnt hurt anything since its been bypassed. the vavle is right against the fire wall on the passenger side. two heater vhoses go into it and a vacuuum line as well as a wire plug. to by pass it take the two tubes off and buy a little piece of plastic piping(bought mine at a parts store and its made dor connecting heater hoses together it was like $5) conect them together and clamp it on and thats it.
new VSV from toyota is about $150 us. there are no after market parts for it that ive found

Thanks for the information. I own a 1989 Supra turbo and the problem has been fixed. Now I have heat. Replacement part way too expensive. Thanks again

If its just the electrical VSV not working, you should be able to just port the vacuum direct to the diaphragm and not have to mess with the heater hoses.

EDIT: I didn't realize that the VSV wasn't covered in this thread.

In the MKIII FAQ you'll find a much more detailed thread about the VSV and blower resistor. I didn't like the thread that was in the FAQ, I've replaced it with one with just the relevant information.
No heat? The two most common problems HCV VSV and blower resistors.

Had the same problem with the VSV solenoid being busted on my 89 turbo. Searching on the net, came around this post http://www.supras.com/06/techcenter/display.php?QID=58 . The part costs around $35.00 from Toyota (for Camry). It is the same solenoid, but the connector is different. Just cut the old VSV connector/wire as close to the VSV as possible and solder two standard female connectors (like the ones used on speakers) and you are good to go on the freezing cold.

Toyota part # 88690-32280
