How much anti freeze should my block and exhaust manifolds hold?
 

Motor is a 502. How many gallons of anti freeze should the block and manifolds hold.

Have four gallons ready to go and you'll have a little left over.

I used 5 because I wanted to to run out for a while while I fogged... Worked great. I used muffs on the outdrives with about 10' of garden hose attached and filled a 5 gallon bucket with antifreeze.

We usually run 6 gals. through anything we winterize, better safe then sorry. Earmuffs, a 5 gal bucket and let her run till it is empty :D

I drained the block......pulled the thermostat, filled the block with 3 gals. thru the hose off of the t-stat housing, filled a 5 gallon bucket with antifreeze and ran 5 more gallons thru the engine and exhaust with a homemade bucket/hose/muffs setup. Fogged the motor real good right before the bucket went dry..........Better safe than sorry!! I sleep better when I overdo!! :D

We Drain The Block And Manifolds Then Use 5 Gal Per Motor

DITTO.......but we use 6 gallons for good measure also give the fogging a bit more time before all the freeze is pulled form the bucket.
