What motors will interchange in the 1999 dodge intrepid?

check a parts store, and see if parts for another model have the same number...same part same engine.. also a junk yard professional...call a couple for varied opinions.. also everyone should have a manual for their vehicle, and the local library should have a SHOP manual available in the reference section--make copies of the right info and read up..you'll be a pro in no time ...good luck:)
