before removing the old one ,match the new one.
with the new one in your hand,look very careful screw by screw ,hose by hose, location by location .
the new radiator SHOULD BE identical or don't even try it.How hard would it be for me to change my own radiator?Not hard.
Drain your water.
Disconnect all your hose.
Disconnect your transmission lines.
Unbolt your mounting brackets.
Remove the old radiator.
Installation is the reverse.
If you pay attention to how the old one comes out, putting the new one in is a snap.
