Plastic weld

[Kklim]

The plastic top of my radiator has a very small crack or hole. Only leaks when it's hot. Cause is faulty radiator cap (changed liao). Any DIY plastic weld or workshop that does such repair to recommend? Thanks.

would  be good if you can post picture or photo of the crack. there are some types of fillers and silicons which can resist temp and also high tack strength

Google "epoxy putty for plastic" or "epoxy weld for plastic".

Update: Bought a new radiator from Tan Chong from Lazada Malaysia but mechanic said it's for manual (mine is auto). Returned for full refund and mechanic changed the top cover (crack was at neck) and going-to-break clips for RM220.
