I am going to replace my Oil cooler lines and my heater hoses this weekend. I have noticed that the heater lines that go from the firewall to the engine, one end has a fitting and some type of quick disconnect. and the oil cooler lines appear the same. Has anyone replaced these and are there any special tools needed to disconnent the fittings. It is a 98 C2500, 5.7 Vortec, automatic, ext cab.

Thanks Darryl

the oil cooler lines have a plastic coller that you slide back and there's a metal clip you pull out and the oil line comes strait out you should be able to get them with a pick,if your talking about the coolant fitting on the passenger side front of the intake manifold you squeeze the plastic tabs together and pull the line out once you disturb the fitting i would change the o-ring or buy a new fitting i found the fitting in the help section at autozone,i found that WWW.OEHQ.COM sell the lines and fittings also
