vacuum switch on water neck...

Never heard of a water neck. Can you describe roughly where it is on the engine?

He means the coolant outlet housing. The part he is talking about I think is the VSV.

Here's a link to what i think is the part you are looking for. Apparently its called a bimettalic valve. Its relatively cheap too.

all this leads to are mirrors.

The first one's it.

That's the purge valve for the charcoal canister (although, as other posts have stated, for some reason Toyota calls it the "bi-metallic switching valve") -- lets air through once the coolant gets to a certain temperature, no air through when it's colder. OEM part number 90925-05068 . $80 is obscene -- MSRP is roughly $40 (just bought one from my stealership in the last month, and they always charge list, no more, no less). Should be able to find aftermarket for $20 or less...just search for the OEM part number.

If you're feeling lucky, there's a guy on fleabay selling junkyard pulls for pretty cheap (for some reason, he has them listed as a BVSV, which is a different vacuum switch). I wouldn't really recommend a junkyard pull for this part, 'tho -- the plastic gets really brittle after a while.

www.toyotaoemparts.com has it for $45.62.....MSRP is $60.82
