I know this is a common problem with the blazer and mine were leaking so time to change them (radiator to housing). Now both lines are leaking real bad at the radiator. Is there a trick with the clips or something that im not doing right. Thanks

 

I wouldn't say that there's necessarily a trick to it. You have to make sure that the lines are completely seated in the inlets before you put the clips in. I just did the job a couple months ago on my Jimmy and it went well and was pretty straight forward.

Check the lines again where they go into the radiator. There should be no motion.

 

I replaced both the fittings on the radiator and no leaks now. Thanks for the help
