cooling not so cool
Well i am stoked and happy to report all my cooling woes are gone. it will hold 185 all day long in hot *** weather. can be in stop and go or highway. we are good to go.
here is what we did.
1. block flush
2. high flow water pump 8 vane with backing plate and stewart components high flow 180 stat.
3. reduced the size of the pump pulley to 5 3/4". the crank pulley remains the same at 6.5"
4. installed a COLD CASE two row 26"radiator with 1 1/4" tubes. MORE ON THIS LATER
5. installed the factory shroud to the new cold case. sealed all areas so shroud to radiator is air tight.
6. installed a fixed 7 blade 18.5" fan. ended up doing away with the clutch in order to get proper fan to depth in shroud. about an inch is what i ended up with.
7. installed lower radiator hose spring
8. hood to radiator support seal is in place.
9. mixed green antifreeze in about a 60/40 water to antifreeze ratio. Added royal purple ICE mainly for the extra corrosion inhibitors.i filled the block first before i bolted the stat and upper hose. this allowed most all the air to burp out.
Fired it up and first thing i did was hold something up to the radiator to see if it was pulling. it about sucked the thing out of my hand at idle. i then closed the hood and held it to the exterior grille and it still pulled it in at idle. NICE, that was a heavy absorbent pad i held up to it.
Shot temps at a few areas. stat housing was 173, upper inlet was 151, and lower outlet was 106. this was after idling in driveway for 40 minutes.
