i have a 98 f150 4.6 liter 4x4 supercab i already had the coolant flushed. i hear water trickling from the heter core area just when i eccelerate in park or in drive. might be a blocked air trapped? or something has anyone had the same problem?

 

I am hearing the same thing too. I changed or flushed the radiator and added new coolant about 2 mths ago.

I have a 1998 f150 4.6L v8... 67,000 miles.

 

Sounds like you guys have air trapped in the cooling system.

 

how can we get the trapped air in our coolant?
