Where is the cranksensor located on 98 century not by balancer is it under coilpack in rear?
There are two of them. One is located directly behind the harmonic balancer or on older models beside it, and it looks like a half moon shape. If it is behind the balancer you have to pull the balancer and the sensor is held there with 2 bolts. The other one i can not find and can not find anything on it really. Sorry.
ALL harmonic balancers for ALL American car engines (and all other vehicle engines that I know of) are in the same place. They're integral to the front engine pulley that drives the serpentine belt or fan-belt, whichever your engine has. Yours has a serpentine belt. Some shops call it the "harmonic balancer", others call it the "harmonic balancer pulley", still others just call it the "front pulley". It's the same thing.
