Default New radiator?

This morning driving to school, I saw smoke coming out from the grill. The weather was cold but I don't think that would cause smoke coming out of the grill area. I parked and popped the hood and smoke emitted from the side of the radiator and fluid is visible in the seems, and the smell was definitely coolant. And further observation, the reservoir was almost empty.

02 wrx @ 103,000 miles, is time for a new radiator ?

I am probably bringing it to the dealership, I heard better aftermarket replacement ones, but which ones equal or surpass OEM quality and reliability, but with OEM fitment, meaning no special modification required to install.

Any opinions welcome. Thanks.

Well we've started to see a lot of radiator issues popping up on the 02 WRX now that they are approaching the 10 year mark. We've probably replaced about 10 in the past year.

As for bringing it to the dealership, only do that if you want to get robbed.

If you are in Queens, I'd suggest coming out to us here at AZP and we can install an OES rad for much less than a dealer including parts, labor and new coolant. Tack on a little bit extra if you want new Upper and Lower hoses which we suggest as those often wear out around 8-9 years/100k miles.

We also have Saturday appointments available tomorrow too.

A lot of the 02/03 radiators are failing, in particular at the plastic end tanks. I'd replace it with an all-aluminum (I went with a Mishimoto). Take it in to a good 3rd party shop, as mentioned above, or do it yourself if you're even slightly mechanical. Definitely replace the hoses and clamps while you're at it, and some people go ahead and replace the thermostat, as well.

I wish I was in Queens right now, definitely would have pay AZP a visit, but currently in Tallahassee Florida, in school and don't have the tools, time, and patience. lol.

Anyone recommend Tallahassee shops that knows Subarus? I read good things about the Mishimoto, but If I need to bring it to the dealership they won't install it. Are the "newer" OEM radiators improved upon the original my02.

MSRP at a dealer is $374, and the design hasn't been improved much if any. You will still get plastic end tanks.

To replace a radiator you need a screwdriver and 10/12 mm wrenches. Thats it. It might take an hour or so, its well worth your time to do it yourself.

call around to local radiator places

I have seen these radiators go for pretty cheap....

and changing one is less than an hours job with no special tools or ability, really.....getting the bubbles out of the system is the hardest part

Thanks for everyone's input. I've decided to get a Koyo. I noticed that the one for the my02 is R2450, which is without the fill top, while the R2704 for the 03 to 07 has one. I would like to get the one that does, would it have fitment issues and also I believe some new hoses are needed as well.

These are the parts supposedly replaced the original 02 radiator.

45111FE101, 45175FE010, 45162FE010 AND 45162FE000

The first p/n is the radiator and the last 3 are hoses. If I were to use the R2704 radiator, I would need those 3 hoses, correct me if anyone have done such install on their 02.

You will need the hoses that go over to the overflow. We've had to fab them up before for customers. Also don't forget a rad cap too.

I'm about to order everything. Just wanted to confirm, so using the 3 overflow hoses, I will be able to install the R2704 Koyo with the top filler hole on my 02 which did not have one and the radiator can be bolted on to the 02 with no modifications ?

I've been searching and trying to figure out if the 03-07 Koyo is any different besides the top fill from the 02 specific one.

Thats what happened to mines. It was really cold morning and the windshield was frozen, so i turned on the defrosters and the radiator started leaking ever since. It smoked because it was real cold, but it sounds like your radiator is gone too. How many miles ? and are you seeing radiator fluid all over the top and side of the radiator ? if so, the seal between the radiator and plastic end tanks is done with.

With 103K miles on it I think it was time for a new radiator. I'm gonna upgrade to all aluminum while at it, but 175 for the koyo OEM replacement is an excellent deal.

If you don't want to make t connectors, I emailed Genuinesubaruparts and they told me the original radiators for 02s are not made anymore but the substitute is available with part numbers:

45111FE101, 45175FE010, 45162FE010 AND 45162FE000

first p/n is the radiator and the rest are hoses. Is that p/n the same as the OEM radiator used on 03-07 ? anyone?

Simple google search for 45111FE101 concluded that it is the OEM p/n for the 04-07 radiator. Therefore by using the other three p/n, you can use aftermarket 03-07 radiators on the 02, if you do not want to fabricate or rig anything.

This is from Jamie of Chaplin Subaru (genuinesubaruparts.com)

radiator
YOUR OE RADIATOR IS NO LONGER AVAILABLE FROM SUBARU
IT HAS BEEN REPLACED WITH THE FOLLOWING WHICH MUST BE ORDERED AS A SET

45111FE101, 45175FE010, 45162FE010 AND 45162FE000 Qty 1 EACH.
Rad hoses:
45161FE050
45161AE020

I'm sure if the original hoses are the same as the ones listed.

The 3 part numbers after the radiator p/n are the additional hoses needed for the conversion to the 03-07 style radiator. I believe it is for the draining to the reservoir.

I have an 05 WRX (~90K miles) and had a very similar situation tonight. After I limped home, I found there was coolant pretty much everwhere all in the radiator fins and around the radiator. Does this seem characteristic of the top seal on the radiator having gone bad? I couldn't find a single point of leaking...

Can anyone confirm that the part numbers for the thermostat and gasket for '05 WRX are 21200AA072 & 21236AA010?

Also, would the conditioner be necessary if I intend on switching to an aftermarket aluminum radiator?

I had same issue about a month ago, and replaced it with slightly used oem radiator for $150, and it's been a month now, and this morning, it started smoking again, but I don't see anything leaking from the radiator, but under the car.
I hope it's just a hose that's leaking, not the gasket
