pre-cat heater blower.

6 posts in this topic

Hi all. 

Just noticed that I'm not hearing the pre-cat heater blower on start-up.

Is that a normal cold weather thing?

Or is this an issue that needs to be addressed?

Thanks!

what in the world is that?

It's a little air pump that blows air into the catalytic converter at startup. Sounds kinda like a coffee grinder without the beans in it.
