[V8Vairs] cooling

Denny:

Could be a number of things.  Do you have a high  pressure surge tank?  I 
used a C4 Vette surge tank up near the "fire wall"  in the front trunk of the 
car.  It is important to get all the air out of  the system (once water 
turns to steam, it supposedly doesn't transfer heat  well).  I have multiple 
bleed valves in the car (on the long tubes in the  trunk, in the top of the 
thermostat housing), and I use a cooling system  pressure tester to pressurize 
the system, then bleed the air off the  bleeds.
 
Also, I had ongoing problems with my first aluminum radiator (installed  
while still using the old 327 engine).  The old engine had a LOT of  
rust/sediment in the cooling jacket that plugged up the radiator.  
 
I did a test with a different radiator propped up against the front of the  
car, with extra long hoses up over and under the hood (and propped my 16" 
fan  behind the external radiator).  Worked like a dream.  I now have a 31"  
wide 2 row Griffen Aluminum radiator in the car, and it runs 170 degrees 
(using  a 160 degree thermostate).  Oh yeah, I have a new (different) 327 in 
the  car.
 
Is your engine one of the old style Chevy blocks (283, 327, or 350)? or do  
you have an LS?  LS engines are meant to run over 200 degrees.

i.ve put 700 miles on the car . 
pipes from the rad go  into the car down the fire wall under the car, then 
up to 
the motor. last  week i ran the hoses from the eng to a barrel full of 
water, it 
ran  160/185. i put a 7 fin blade on for testing, also built a shroud for 
the  
rad.


again  thanks

How  does the air exit  the trunk area?
