Mysterious coolant leak. Reservoir is low and needs refilling often. Mechanic has performed pressure test to no avail. No coolant on ground at any point. No visible signs of leak. This began right after 2nd cracked flywheel was replaced. At the same time a lifter knock began as well. 1st flywheel was replaced at 103k (3k outside of extended warranty). 2nd flywheel replaced at 143k. Van is kept in mint condition, oil changed every 3k w/o fail. Vehicle seems to be in otherwise terrific condition. 1st and only owner. Date referred to is date of 2nd flywheel crack.
