Hello Everyone
I have a 2003 w900
I am looking for this style radiator here is the part numbers provided by the kenworth dealer
3s52633mmc
3s9853mmc
Dealer is telling me that this radiator is discontinued and there is no aftermarket part for this radiator. This style is set up weird where you have the Air to Air sits on top and the radiator on the bottom. Help me please.

The first number you list is available. It is the image you posted. 3S52633MMC KIT-SERVICE ALUM RAD REPL/W900L
Is it the second # that you also need but can't find? I would have the dealer double check the #.Rideandrepair Thanks this. -
You're better off having your existing radiator recored/repaired at good radiator shop instead of replacing it. Joe's in Hubbard OH is one of the best I know of.
Rideandrepair, JB7, Bean Jr. and 1 other person Thank this. -
Yeah I don’t know anything about that website that’s why I haven’t ordered from them yet I don’t know if they are legit or not I called them and emailed them and haven’t received a response

I found the problem why my radiator started leaking but I still can’t find this style radiator, I am hoping tomorrow the radiator shop can fix it crossing my fingers on this one

1-800 Radiator is who the Peterbilt dealer I work at uses for non-Paccar brand radiators. I haven't had any issues with the fitment of them versus OEM but can't speak to their longevity.

Why can’t you upgrade to a standard style W9 rad and cac? Next time you need a radiator, it’s a standard replacement.
JB7 Thanks this.
