Hi everyone,
My Fiat 500 presents some strange behavior. It acts like it's choking when the radiator fan is on.
I noticed the exhaust vibrates once every few seconds. I didn't notice a significant drop in RPM. It sounds like pressure is building up on the exhaust end.
I made this video here to describe the issue:
When cooling is not required by the fan, it behaves fine. AC compressor was off for the entire test period.
Not sure if this can be caused by a split exhaust manifold, which I'm primarily suspecting for a tappety noise which I detailed in this separate thread.
Is there anything I can check myself before visiting a garage? I cannot understand how engaging the radiator fan causes this.
Thanks in advance!
