My '87 5kcstq - 124k miles - has a strange radiator leak - when hot, it holds pressure fine - shut it off and let it cool down and it leaks along the side seam on the end toward the engine. - I'm planning on removing the radiator and getting it fixed or replaced. - Anyone out there BTDT? - Does the Hydraulic pump have to be removed for clearance? - Any advise will be apreciated.
