    I just bought a used, 2006 Tacoma TRD sport double cab with the auto trans and 4.0 engine, and 38,000 miles. On start up i have noticed a chirping or squealing sound, it doesnt do it every time, but sometimes it is loud, once the engine fully warms up it goes away. Im thinking its the belt or one of the pulley's, what do you guys think? Has anyone else experienced this with the 4.0? Not too worried just dont want to let it go if it could potentially become a worse problem. Thanks for any and all replies....Frank

    well, these newer tacomas have an engine tick thats normal, but the squealing/chirping definitely sounds like a belt or pulley. you may want to have it diagnosed for peace of mind, or try some belt dressing(which will only hide the problem for a short time). with that many miles.....belt shouldnt be bad, but i have seen it happen. more than likely though, its probably a tensioner pulley that maybe got dry somehow.

    When you hear the sound, pour some water on the belt. If the sound lessens then keep putting more water. If it stops, then you know its a belt problem.

    Usually soapy water is used to find a leak, but it would probably work here too.

    I was thinking that the soapy water may condition the belt but it would eventually come back, if its just the belt im not worried its the pulleys that could be a concern, thanks.

    PSE makes some pretty good bows, that X-force is unbelievable but im not a speed freak, just wanted a comfortable, smooth drawing, light and short bow and the Black Ice is that and more.Its birth certificate shows 294fps @ a 29 inch draw @ 70lbs IBO. Im shooting 27.5 inches and a 437gr arrow so its probably around 250fps, just fine for what i need.

    By the way, poured some water on the belt and it stopped immediately, started to squeal a couple of seconds later, poured some more on it and it stopped, gotta be the belt. Thanks for the simple diagnostic trick, have a great one guys.

    good diagnosing man.

    250 fps is all ya need anyway.........the super speed bows are just bragging rights anyway. i was thinking of getting a pse diablo, but my wife was thinking otherwise:D, so i'll stick with ole faithful for now.
