I cracked the radiator (the plastic side) of a non-F150 Ford (Edge to be exact) while removing the radiator fan. I read about plastic weld with a high wattage soldering iron, but the location of the crack does not allow access. I also read about superglue and baking soda trick. Does it really work? According to internet, superglue and baking soda react chemically, and generate high heat, locally melting and bonding plastic. Does anyone have a firsthand or second hand experience with this trick?

 

I use super glue for fixing lots of stuff, and with baking soda when needing to build up the area. Yes it does get hot but don’t think it’s going to melt plastic hot.. I would go ahead and give it a try.. Superglue is also great for fixing tires on garden equipment.

 

It will probably work until the system builds up pressure. You could ride around with the cap loose until you can fix it right.

 

Thank you for your advice. I replaced the radiator.

 

Without trying to repair it?

 

If you think a new radiator is expensive, try fixing an overheated engine with warped heads.

 

The plastic tank radiators are not worth attempting to repair.
