Radiator crapped out. :(

So I checked my oil last night and noticed coolant around the top rim of the radiator so started it up and got it to normal temp and noticed it seems to be coming from the top plastic part where it meets the aluminum.
Guess this happens quit often after searching around and checking on reviews for a new one.

So I found a CX Racing radiator that fits the budget and curious if anyone had any issues with them?


Thanks guys.

aluminum radiator FTW

I have a Koyorad radiator (after my stock one burst at the top plastic hump), and have had no issues whatsoever.

Contact your local dealer on what they utitlize. When my Foz's radiator took a crap, the dealer utilized an outside source and I'll quote "I wouldn't ever put a OEM piece back in any Subaru and haven't for close to 10 yrs".

yeah I guess the OEM radiators are junk and known for going bad on the top "at least on the bugeyes anyway".
I'll pick the Cx up and let you guys know how it holds up gonna pick up the slim fans with it also.
Ill hit ya up Randy if I ever need any other spare parts man thanks.

Koyo radiators are nice (I have one too). They fit well and look snazzy in the engine bay.

*Update*
Got the new radiator installed during the week with new Samco hoses.
I got slim fans also but need to do some research on how to wire them up.
The fans have 2 wires but OEM fans have 3. From what I gathered so far OEM fans have 2 speeds but since I was unaware of the harness not mating right and didn't know what wire does what at the time of having everything apart I put it off till I find out what will work.

Here's a quick shot of it.

Looks like it still utilizes the expansion tank, is that correct.
I'm looking to upgrade mine and want to do the radiator in the future but don't want to throw my money away.
Wondering the same about your koyo John.

Randy, you want the local dealer here to give you a quote and I can go get it and ship it to you. I think it was 259.99 or similar.

^ what!

Edit: I get it Paul, 260 vs 620. That's fine. I'd rather the all aluminum though

Yep, fitment wise, the Koyo radiator is a direct replacement for the stock radiator. The stock fans and overflow tank attach to it the exact same way that they do to the stock radiator. The only thing I had to do was purchase a pack of metric bolts because the bolts that held the fans to the stock radiator were actually self-tapping screws whereas the Koyo unit requires normal bolts.

Because the unit is thicker than the stock radiator, I ran into two issues: (1) the upper radiator hose (Samco silicone) had to be trimmed to allow proper clearance around the pulley and the fan and (2) the lower grey plastic connector harness for my passenger side radiator fan melted from being too close to the headers. I didn't have heat shields on them, so that was probably my own fault. I re-routed those wires and zip tied them under the power steering hose, so that solved that problem.

Here's the best pic I have of it installed.

^ Upgraded with Samco hoses to John I see.

Yeah everything fit up perfect same layout as OEM. I just had to adjust my overflow a bit but besides that flawless. Still holding up fine also.


Still bummed about not getting to install the slim's though.

I contacted CX like you said Paul and asked if they sold a harness and unfortunately they don't, however I also read somewhere that OEM fans are the cats' a$$ when it comes to cooling and slim's don't put out as much airflow as them.
