Thumbs up Air in radiator system...

Hey everyone,

I have read so many of these posts and replies... From having a head gasget leak to raising your car up to crazy hights to bleed the air out... Rediculous!

I have a 2005 3.5 SE Altima with 189k hard miles on it. This "air gurgling under the dash" issue did not start until I replaced the radiator

First off, it is normal for air and a little coolant to travel from the radiator to the reservoir and back into the radiator. If your reservoir has the proper coolant level (hot) line, then no air will be sucked back in.... No coolant in reservoir = air being sucked back into the system.

90% of all these problems can be fixed by just replacing your radiator cap with a new OE Nissan cap.

While driving with your heater on and with a load on the car (freeway), the air will eventually move around and escape out through the reservoir in a relative short time. Remember, I think the only time the air will escape is just before the fans come on, it has to be hot for the steam to escape.

Problem solved.

Hope this helps...
