I did a radiator flush on my 2000 4.0 TJ today. My first time doing anything like this and I was told it would take more than 2 gallons in the radiator of antifreeze. For some reason though it took less than 2 gallons before it was full. Is that ok?

Refer to your manual for fluid capacities. Don't forget to burb the system, leave the cap off the radiator and run it 'till the engine warms enough to open the themostat

Ya, no owners manual. But I didn't let it run without the cap to let out the air bubbles.
