I have 96 Chevy Blazer (automatic) that's been making a slight gurgling noise (sounds like water - think "babbling brook"). I only recently got the vehicle and I'm thus not too familiar with what's normal and what's not.
Does this sound like something to be concerned about, or is it normal for this make/model/age?
- Makes noise after a cold-start and while idling.
- Recently replaced the radiator (about 100 miles ago)
- 162k miles
- I'm not sure if it was making this noise before the radiator replacement or not; I wasn't really paying attention.
