    I recently filled the fluid resivoir for the radiator in my 77 Blazer to the top, way more than what the cold line suggests to be in there. After driving it for about five minutes I found a pin hole leak toward the top driver's side of the radiator. What kind of quick fix can I use to make this radiator work for a few days. I need to make a 2 hour trip with it on Tuesday to get the VIN plates straightened out. (Someone replaced the original VIN plate before I bought it and they will not give me tags for it until I get it straightened out.) I have to make this trip tomorrow. Any help would be appreciated.

    Use epoxy. the nipple that the tube goes on to for the over flow can is broken off. I epoxied it on there over a year ago and it does not leak. Just gotta be careful not to hit it or I will break it off. I used the epoxy that is two parts and you gotta mix it. should get you by for now and a long time to come. Hope it helps.

    I guessing it will if it is only a pin hole. my whole nipple was broken off and it is still holding strong now. try it, and especially if it is only a temp. fix.

    Thanks a lot. Sounds like it will work fine to me. I can't wait to get everything straightened out and put my rig on the road legally. Then I will be able to start making the big mods!!!!

    I noticed that you are 17 too. Where you from? I'm in Maine. Just wondering.

    jb welld will work better. epoxy will work well too. they make a "special" radiator epoxy also. this sometimes had a bit of metal in it. kinda like JB weld. ethier way, a pin hole can be sealed by both.

    1974 Chevy Blazer Cheyanne. lots of plans for it....
    but it is on 33's now, with saggy old springs. i am in so cali if ya got any parts for me.

    I have used "Alumaseal" before with good results. It is a power that you pour into the radiator. Works well on places that you could not get at as well (like heater core).
