It is plastic
On my 91 it is metal (copper, or an alloy I believe?), although I have never heard of a plastic radiator.
Aluminum core, plastic side tanks.
Usually a radiator is made of metal. Plastic can not take the pressure. A hole can be fixed by welding. A radiator shop can tell you for sure.
Aluminum core with plastic side tanks.
cars don't have plastic radiators, if they do the plastic would probably melt, and the compound of metal cools and heats quickly which is useful in cooling water.
If it is a plastic radiator and it is stripped, no, if it is metal yes.
it is at the bottom of the Radiator on either the left or the right side...it is a plastic or metal threaded tab
I think metal tanks are needed. Many newer have plastic.
For metal radiators, ideally, it needs to be braised (not usually a do-it-yourself job). However, if there is too much metal fatigue, it must be replaced. For plastic radiator parts, ideally, the part should be replaced, and any other plastic radiator parts should be inspected for signs of impending failure since they are likely to have similar life spans.
No there metal not plastic the top has plastic
melt the plastic to the metal
