[QUOTE="Max8, post: 1048010, member: 74747"] I had a similar problem with my 2005 Lt v6 sport trac. After change thermostat housing and water pump I had a squeak that would start at start up increase with rpm then after a bit stop. I went back and changed idler pulley with no help. It continued for awhile then truck would shut down randomly when squeak started . Finally found harmonic balancer rubber was torn @ 75% around allowing balancer to contact the crank position sensor causing the squeak. Squeak would stop once balancer trued up. When I finally found it it had ground about half way thru the sensor exposing the interior and grounding out on harmonic balancer causing the shutdown [/QUOTE]
