Just a quick video showing how I replaced the Heater Control Valve in a 1998 Toyota 4Runner. This will be the same process for many Toyotas. The vehicle was on it's way to my house to have the codes read because the check engine light had come on. The owner didn't realize that they had lost all their coolant due to the broken heater valve and they overheated and the engine shut off. Luckily after letting it cool down and replacing the valve and filling it back up with coolant the engine started right up and sounded just fine. I also showed how to free up the heater control valve cable which was really stiff and difficult to turn. After spraying it with B'laster Multi Max lubricant it worked much better and I was able to turn the control smoothly with much less effort.
Thanks to B'laster for sponsoring the video.
Tools Needed:
10mm Socket and Ratchet or 10mm wrench

Small Phillips Screwdriver
Funnel
Coolant/Antifreeze

So i have a 2000 toyota 4 runner that was given to me i have a/c but i dont have heat. My heater core is bypass and the a/c line is cut im assuming for the heater is there any way you can show me what your heater core goes to and where the a/c heater line goes too? Would you say its my heater core that leaking because its not connected to the heater valve. Im not entirely sure what was the issue its just what 've been told

[@DantheFixitMan]

Most likely the heater core was leaking which is why it was bypassed. Unfortunately, I don't have this vehicle here, but you can probably get quite a bit of info from the forums or just try a google image search for your engine bay.

How much coolant will I lose when switching this out?

[@DantheFixitMan]

Maybe a quart or so, this one was already empty.

Excellent video. The cable clip can be difficult, thank you for showing how to unclip it.
