thought I had a leaky heater core but it was the PLASTIC HOSE connector leaking. my ? is how do these plastic connectors release from the actual heater core tube? they willrotate aroundeasily. as if they utilize an "o-ring" seal setup. any info will save me some $


BTW it is a late 99 1500 Silverado

thanks

 

it takes a special release tool...a big parts house may have one

or saw ift off...but be careful not to cut the core

 

dremel, tight fit but got 'er done

thanks for the reply
