Clicking Sound During Warmup?
Hey all RX-8 Gurus,
My question is about when I'm warming up my car I hear a clicking sound from under the hood.
It's not every second just every 30-45 seconds I hear a click noise.
Is this normal or something I should worry about?
I usually have the heater running and that's it.
Thanks in advance for any help.

Its probably an idle position sensor of some sort. Personally I've never noticed it in my 8. But I have noticed it in my Explorer. I had one go bad in an Explorer Sport Trax I used to have.

I am thinking that it may not only be poor spark plug wire connection to the plugs, but it may also be the purge solenoid doing it's job. That depends on the exact nature of the noise, though. The purge solenoid vents fuel tank fumes to the intake manifold and when it is active, it makes a chattering noise that sounds just like a boost-controller solenoid (because they are nearly identical in design).

Is it possible that it is the exhaust system expanding as the engine heats up? (especially if you have an aftermarket exhaust system)
I would still check the plug wires as they are notorious for the terminals at the spark plug loosening over time. You can usually gently pinch the plug boot and that will firm up the connection.

I'm pretty sure what you are hearing is your cooling fan cutting on and off. The relays on the fan cutting open and closed can click pretty loud. Listen close and see if the clicks coincide with the fan cutting on and off.... The cooling fan cycles whenever the heat is on or the AC button is pushed on. Try cutting your heater/AC fan to 0 while it is warming up and see if the clicking noise stops.

Single Click every 30-45 seconds
Vegas bookmakers have lateralus suggestion of cooling fans clicking on as the favorite at present - odds at 5 to 3. Charles Hill suggestion of insecure spark plug wire in the #2 slot at 2 to 1. Rotary Machine RX suggestion of air pump shut off in the #3 spot at 4 to 1.
