Coolant gurgling after driving around? After the car reaches normal operating temp (Never checked otherwise) if you listen closely... you can hear the coolant boiling/gurgling. It's a very odd sound that I never heard with my LT1. Is this normal? Or is this common amongst a typical problem?
make sure your coolant isnt low this can cause air to get it and when it goes through the heater core you heat it gurgle. make sure the level is ok. its not normal but i have heard it on other vehicles. as long as there is coolant and you get heat out its ok. if you dont get heat out ot the vents or if you wanna try it anyways. WHEN COLD take the cap off and fill the RAD to the top now let it get to full temp. turn the vent on high heat and rev the car to 2-2500 for like 2 min and do that 5 times this should help push any air in there out. let it GET COLD and double check the level.
good luck hope this works for ya

Also go buy a new radiator cap. If the cap isn't building pressure the coolant will boil easily. A new cap is only about $8 at AutoZone and should be replaced every couple of years anyway as regular maintenance.
