I called a Lexus dealership and they quoted me $110+ for a heater control valve for my 1994 LS400.

Does anyone know if Toyota has the equivalant part in one of their cars?

Thanks.

Did your car stop blowing hot air? My wife's heat just stopped working, and I'm trying to find out if this is the most likely part that probably went bad??

Chris did you ever get your heat fixed? I'm experiencing similar problems. No heat, fan works fine, coolant is full, thermostat is fine. I'm guessing it's the heater control valve or blockage in the hoses that leads up to the heater core.....any insight would be appreciated, thx...

Ive got a leak coming from the rear coolant bypass where the metal tube goes into it. shouldnt there be come sort of clip or gasket on this tube? I can wiggle it out pretty easily. Does anyone have any diagrams or pitures or experiance with this?

thanks

f.y.i. this is on a vvti 4.0 its actually a gs400, but same engine on the LS400

I don't know if were talking the same leak but I had a coolant leak near the access panel to the flywheel near the rear main seal and it appeared to be coming from the the water bypass tube interfacing with the water pump. I just changed the water pump and suspect the o-ring was misaligned or was the wrong size. Is this the leak your talking about? Do you know if there is a way to change the o-ring without removing the pump, such as access from the top (remove intake manifold and pull the tube out of the pump? Either way it looks like it's going to be a real pain to get to!!!
