What's up everyone! My '02 LB7 is having an issue. It's using more coolant than what I think is normal. 175K miles and the engine is pulling strong as ever; No signs of a leak; Blowing clear exhaust. Thoughts? 
Help: LB7 using coolant

Mine was water pump. never a drop on the ground but it would drip from the weep hole when it was running and at operating temp.
Just replaced the water pump on mine. Had the system pressure tested, leaking from weep hole in pump. Garage said 8 to 9 hours and wanted $875 to replace pump. I replaced pump in 3 hours for $125. Have it pressure tested to verify leaking area.
Good luck.
