I just bought a certified car and I noticed a whistling sound (Like out of kettle)That seemed evident when the engine is warmed up and gets louder upon accelaration. Its more annoying if anything else… I told the dealer but “they can duplicate the noise”… I owned a Jeep 2000 Grand Laredo before and I never heard this noise like this before. Is there anything I can do about this or a mechanic to check on specific part of the engine? Please advice.
Find a mechanic with better hearing. The dealer you bought the truck from may be “suffering” from “selective hearing loss”. This could be worstened by dollar signs getting stuck in the ears.
