I recently installed a coolingmist system on my truck. It seems to work ok, but when the pump runs there is a constant clicking noise (like a relay) and it is like the pump is being turned on/off every second. I expected a more constant pump noise.(like a washer pump)

Is clicking noise this normal?

I can take a vid if needed.

well, i searched on here and online before I posted. But I found the answer I was looking for. The click noise is the 150 pressure switch on the top of the pump, and is a normal condition.

you can delete this post or leave it for future searches.

Hmmm..... the video will help. If the system MAF or MAP based?

yes mine does the same , turns on and off with the pressure switch.
