Early 853's with MLS
The motor has about 2500 miles on it now and it hasnt really lost any coolant in the last 2000 miles..
I plan on changing heads middle of the year but i use this truck everyday and work out of town 80% of the year..
At the time of install i had no idea they needed the graphites

My question is should i go ahead and swap over to the graphite ones or leave them be untill i swap heads (if it doesnt start a river of coolant down the block)??????
