Fixing radiator shroud

So a few years ago the top mounting ears were broken off of my radiator shroud. Now that the blazer is back on the road I need to either fix and reinstall or get a new shroud. Wondering if a plastic welder would work? Not sure what the shroud is made of.

Super glue and baking soda , I've used it to repair center consol cracks and a ton of other plastic parts .

Re: Fixing radiator shroud

I have the same issue and plan on using polypropylene strips and a heat gun to "weld" a replacement corner back on.

Found some good info on this site: https://www.polyvance.com/vista.php

I have the strips, but haven't found the time to do the job.

Re: Fixing radiator shroud

If you have a local body shop that uses the 3M Automix plastic repair it should take about 20 min. The stuff is a two part mix and you use an adhesion promoter on the surface. Sticks like it never broke!The stuff is a little pricey and you need an applicator gun but the shop would only use a small amount so they should not charge much. At my shop if someone came in with that I would just do it and say "Catch you next time."

Re: Fixing radiator shroud

JB weld on mine, overlapping is important. Holds up to heat and other road crap.

If you want looks just overlap, sand and paint.

Re: Fixing radiator shroud

I used a two part mix called PC-7 I got at Ace Hardware when I repaired my 4x4 shroud. The mount tabs were split/cracked and I used an piece from a salvage yard shroud cut to fit then liberally "glued" it with the PC-7. Been repaired for several years and no problem. Also used the PC-7 for a dash repair on my '71 Chevelle with another overlay. Still holding tight after several years. Just a thought, good luck with your repair.

Re: Fixing radiator shroud

I ended up using the super glue and baking soda. Seems tough enough. Not pretty but has been on for a few trips to town and hasn’t broke yet

Re: Fixing radiator shroud

This is the thread where I first heard about the super glue and baking soda trick from Grumpy old man. Both the top mounting ears were broken off of my radiator shroud and I finally got around to fixing it last weekend. Near the bottom of the shroud it had some minor broken up areas, and I removed a small piece of the plastic from there to make new ears. Super glue and baking soda, it sure is great. I've used it to repair a lot of stuff around the house and a few things on the truck.
