[V8] Thermostat orientation

[Jason Wilkerson]

Freddy,
  Had the same problem on a v8 once.  Ended up being the "Spiral Noodles" that go through the tubes on the heater core (I think they are inside to make the heater core more efficient?).  I guess after all those years they just break down and clog everything.  I would remove both radiator hoses and back flush the radiator.  If some yellowish brown plastic comes out you have found your culprit.  You will have to remove the radiator to properly flush it out and then on to the heater core (Really fun job).  If you don't do this you will be right back where you started very quickly.  Hope this makes sense.  Good luck!

 Thanks for the replies everyone - it
 was just one of those moments where you
 question stuff you know the answer to!  Spring indeed
 goes in toward the
 block, in fact although the assembly will allow for reverse
 orientation, it
 is pretty clear that it won't flow coolant that way.
 
 In other news, I am still running hot.  While under
 way, the temp is high
 but manageable.  But when stopped and idling it creeps
 up quite high.  Upper
 rad hose is very hot to touch and the lower is just
 warm.  Unfortunately, I
 am thinking the radiator is plugged - which was my original
 fear.  Guess I
 can't complain after 25 years of good
 service.   I am also due for t-belt
 service (time not miles) and really starting to think it's
 all not worth
 pursuing.  The car has been in the family since day one
 and it's in great
 shape - so it will be a hard decision to see it go. 
 Or, I can put a couple
 grand into it and keep going!
 
 Cheers -
 Fred

 Please pardon the silly question, but I am at my shop and
 can't look this
 up. I am replacing the t-stat in the '90 due to hotter than
 normal engine
 temps.  
 Just to be sure, the spring side of the t-stat goes toward
 the engine,
 right?  (I know, silly question- but I have learned
 never to assume anything
 with the beast!)
 
 TIA
