02 WRX Radiator issue...have a couple of ???
Car = 2002 WRX / Sedan
So apparently my radiator is leaking...a lot. The garage I was at said that when he called Subaru to quote the parts, the guy at the Subaru shop said the 02's WRX's had a TSB on the radiators and to install a new radiator you need to purchase a new set of hoses and some other parts as well as the new radiator. My questions are, is their a TSB on the 02 WRX's ? Where can I get a copy of it. Also, will a stock 2003 or 2004 radiator fit in my WRX ? Lastly, besides the OEM part, is their another alternative that is close to the same price range ? EDIT : One other question. If I buy a Koyo Radiator, will it also need to be re-routed in accordance with the TSB, or can the same old stock hoses be used in it's place ? Also, is this something that can be done on your own without a lift, or do you need a 'garage' to replace the radiator ? TIA - JZ Last edited by ZMANNH25rs; 08-28-2007 at 01:43 PM. |

Everything can be done from the top. There is a difference between an 02 and an 03. However the mounting is the same. If changing to an aluminum be prepared for some minor (?) mods.

I went through the same ordeal a couple years ago. My 02 radiator basically busted at the stamped seams. I replaced the unit with the Koyo one, as it's about the same price as the dealer quoted factory piece, but way better. You can use the same stock hoses, however it is a tighter fit with the larger Koyo core. Make sure the upper radiator hose is not hitting the belts. I have two complaints with the Koyo. 1) The drain plug on the bottom is a plastic screw 2) You have to remove the subframe to gain access to the screw if you want to drain your coolant. Hope this helps.

I had no problem reaching the drainplug on the radiator from the top, in fact it was even easier than w/ oem rad (just remove airintake). Oh, I left out the right side fan, figured with extra volume I dont need it. Most drainplugs on oem rads ARE plastic. |

I had the same problem. Mine left me stranded on the side of the road though. Instead of buying a used radiator or another one from Subaru (which is too much $$$) I bought a koyo off of ebay, got some samco hoses, a crucial racing thermostat and cap, and called it a day.

.....in a nutshell, the radiators on '02's and early '03's didn't have a radiator cap on the radiator itself (only on the resevoir). The newer units have caps on them but will require a metal tube and two overflow hoses when replacing the old set up. I believe this is the TSB you were looking for (courtesy of ScoobyMods & DrD):

My questions with this, is the new Koyo radiators for the 02's have these changes made to it, to accomodate the change in where the radiator cap is ? Or does the newer Koyo models not need this change because they are not prone to leaking ? This part is confusing... |

Yeh, Koyo makes both designs '02 and '03. I went with the '02 design as well.

^^ i 2nd the motion on trimming of the samco hoses w/ the install of a koyo radiator.i trimmed the top hose on just end that bolts into the block,the hose is a little cockeyed but no clearance problems.maybe a slight trim of both ends will yield a better result than just trimming only one end.
oh btw my stocker popped in the same area as everyone stocker! |

I didn't have to trim the top or bottom samco hose, although I probably should have trimmed the bottom one. It was tight, but I made it fit.

Just came accross this thread because my radiator recently cracked as well on the upper tank like the pic above. Does anyone know of where I can get a print out of the TSB? And are the newer radiator models any better? Any feedback is appreciated, I don't want to go through another cracked radiator, if so I'll buy a Koyo later on.
