you cannot be serious...........

 

^ LOL



OLT. what are your thoughts on this?

 

He just used the vac line that pushes instead of pulls. You can just use a different vac line associated with the heater controls, or hell flip the arm around. It's $350 cheaper, make an effort. LOL.

 

Agreed. All credit still goes to O.L.T. for this mod. Saved me a bundle.

 

I'm willing to try this of course, anyone have a completed install with before and after pics so I can use that as a reference to popping what lines where on this thing?

 

Since a few people requested pictures and I had the valve off the car, here is what the modifications I did look like.
Nothing crazy. Just used parts that were already on the car or were laying around on the floor of the garage anyway

 

You did a great job! You might want to attach those photo's so they never disappear.

 

Necessity really is the mother of invention...Saving this until needed.

 

Hahahahaha, I have to agree! Some more <3

 

Do you have the installed pics on the car so newbs like me know what to copy . Not sure how to connect the electrical piece/plug and where each hose is connected etc. thanks

 

I'll see if I can snap a few installed pics. I didn't think they would be necessary since its a direct replacement for an existing piece that's already on the car. Just find it, unplug it and throw the new one in. If you're not sure where it is, look up the FSM for the car.

There is no electrical piece on the new valve. Just keep the old one.

 

i'm a newbie but how do you know if yours is bad and what does it actually do? i noticed when i was replacing vacuum hoses that the hose leading to this solenoid has 1 way check valves on it.

Thanks,
Sid

 

So this thread is a little confusing. So the op makes it seem like swap and go, but theres posts of reversing things, adding screws...Can someone who has done this post up some actual how to instructions. Like after putting the new piece on how to get the heat to work

 

im ordering one for my SC now should I just be taking off the old hoses and attaching them to both ends of this new assembly? Pics of the installed version would be sweet. Thanks

 

As someone mentioned earlier, AutoZone has these under the Everco brand. I bought one but didn't like how it is reverse. It closes when there is vacuum instead of open. So I went to their website and look through ALL their heater control valves. Found four that might be an exact replacement:

Everco / Four Seasons (ebay):
74004 (1.8L - 2.2L Celica)
74636 (3L Siena)
74637 (1.6L Corolla and Geo Prism)
74641 (2L Celica and 2L-2.5L Camry)

Who has time or access to these to find the best match? My local AutoZone don't have these in stock.
