Had a conversation with my dealer on Friday whilst having my FPM375 fitted about the whole warranty thing
they had a FRS in with coolant literally passing straight out the exhaust, when they approached ford to replace the engine they requested numerous photos he said 100 but that seems excessive however he did say that ultimately the decision is with ford and never the dealer and anything that has a whiff of after market will be knocked back and when a dealer says they can cover up after market add ons they cant as the dealership franchise will always come first which i get
he also said that ford only send a new block for engine failure all other existing parts are bolted back on, however and again I don’t know how true this is but ford will/would honor an engine/block replacement even if the car was out of warranty as its a known fault
Naturally the above is a chat with a ford mechanic and not in black and white from Ford themselves lol ?
