where is the heater hose??? Mark3
 

Anybody can tell me where is the heater hose and heater core? (1987 supra 7mge)

Please post MKIII specific threads in the MKIII section.


The heater core is behind the dash. You must (very sadly) remove the dash to access it. There are two hoses which run through the firewall to it on each side of the engine.

Very wired heater,the wind is warm then cool and warm and cool ...
 

After I flash my heater core(actually just use water hose clean it a little bit ) my heater start to work but only work when car is running fast, it was working really good when I drive the car around 55 miles/hour but when I stop at idle, the wind just become much cooler....when I start drive, the wind will come back to pretty warm.......

I replied to you in one of your other threads about the heater:

If you are getting heat part of the time the VSV I mentioned that may be intermittently failing, there may be air in the system, or the heater core may be thoroughly clogged and in need of a chemical back flush. Top off your coolant and try bypassing the valve I mentioned above as they're the easiest things to do.
