I just finished the flush. Everything went well. I was able to flush without the garden hose. I flushed the radiator, then took off out the thermostat, took off the lower radiator hose and flushed. Then took off the heater core hoses and back flushed that with distilled water and compressed air. The old coolant was really clean.

My dilemma: Its supposed to take 4.6 to 4.7 gallons of coolant. I put in 1 1/2 gallons and it wont take anymore. Im guessing theres air in the lines but I cant figure it out. I squeezed the upper radiator hose and the heater core hoses and got a little more in but not a lot.

I just drove about 10 miles and the temp stayed normal. Im hoping that when it cools down Ill be able to add another 2 gallons but that probably wishful thinking. Any thoughts on what to do?


Also, I forgot to mention I started the engine with the Upper, Lower, and heater core hoses off and the heater turned to max heat so I know the block, radiator, heater core, and expansion tank were all empty.
