I have this strange problem, where when I put my car in drive and my foot on the break there is this strange what sounds like to me is a rattle under the hood. It seems to get louder when the AC is on, but there is nothing when I'm doing any normal sort of driving only when the car is in park and my foot on the break, nothing even really during regular idle.
I took it to several mechanics none of you can pinpoint what the problem is, 1st it was thought to be the water pump, so i had it changed but again the same problem, 2nd time it was thought to be a AC hose rattling against the compressor so i had it changed again same problem, 3rd thing I was told was it to be the Alternator belts and bearings.
To me it makes sense since it seems to be louder when I AC is on its drawing from the motor causing some strain. But I'm not ready to commit anymore money untill I'm absolutley sure this is it.
Have any of you encountered and similar such problems and feedback would be really appreciated, also can you recommend a oil additive for noisy lifters.
