Hose help?

dannydavi · 09-30-2008, 12:03 AM

Hey guys... it's been a long time since i've visited but I have a few more questions

researching a possible bhg on my supra and found some other problems along the way.

1. what is the item I circled in blue? just curious.
2. what is the hose called that I circled in red? that way when i'm asking around for a new one I know what to call it

(it has a whole in it)

The item in blue is the heater control valve. The open hose attachments are for the heater hose. It runs coolant to the heater core. The other hose is for crankcase ventilation.

In the blue is the water valve diaphram

and the red is the water line for the heater core.

thanks for replys guys... but that cygnus page is not loading...

have your dealership pull up a diagram of the cooling hoses and you can point to the one you need, its pretty specific and you arent going to find a generic hose that will work right

Wow great reply bill uk.. i'm going to bookmark that site for future use.. And on the topic of the hose I ended up just going with a generic heater hose from kragen cause I live nowhere near a toyota dealership... and it seems to suffice... stopped the leak for sure.

dannydavi · 10-01-2008, 02:55 AM

Also on the same subject of me not knowing what/where things are... can someone tell me if I have these hoses in the right spots? Shortly after me messing around in that area my cruise control and my heater stopped working... and this area of hoses is all I can think may have. caused it all. Also what is the item I circled in white? thanks in advance...
