I have a new cap coming, but I want to make sure I'm not missing anything else before I pull my current one!

I installed my CXRacing radiator tonight. Fitment was 100% perfect, trimmed a bit from upper rad hose and it took much more coolant to fill because of increased capacity.

Purchased from Just intercoolers on ebay. decent shipping but a bit slow due to holidays I'm sure.

They even sent me a coupon code but I don't have any use for it at this time. PM me for a coupon code good for 15% off any purchase from CXRacing. Valid untill Jan 31st 09.

How were you able to use the stock petcock?

I have been having a hell of a time with the drain. That o-ring they sent with it is a piece of junk and too big. I switched to a smaller o-ring and it still leaked. I tried to use some plumbing material (pink stuff) cut in the shape of a circle....that didn't work. Then I put the plumbing stuff on there and then the smaller o-ring on top, which held for about a day. And I am giving it a little extra turn when it heats up, but still haven't had any luck.

I'm so sick of refilling the system. I have probably done it 5 or 6 times now.

Right now I have a nylon washer (like that comes in the assortment packs in the help section of Advance) on the supplied cxracing drain plug they sent and I don't *think* it's leaking.

It seems like they didn't even bother testing the drain or if they did they didn't test it under pressure.

Does anyone know the size/thread pitch of that drain plug? I was thinking about getting a bolt and possibly putting a copper crush washer on it.


P.S. I bought mine off ebay as well. When I asked before I bid how long it would be before it arrived (to SC) if I went ahead and bought it, they replied one business day. So I figured they were drop shipping it from somewhere else. Nope, it was a lie and took about 5 business days from CA.

^^^they might have taken that question to mean the turnaround from order to shipping it out. Even amazon and the like don't have that kind of shipping turnaround, unless you pay the $$$ for overnight.

I removed the o-ring and just tightened the drain plug down, then took a pair of pliers and snugged it down a bit more. I've been running mine now for about a week without a single drop of coolant coming from it.

And it better hold up because I'm driving from Iowa to New Hampshire in two weeks.

I don't think they misunderstood, I think they just wanted to sell it, but whatever. Here was the actual response I got:

"we ship very fast and only takes one day for delivery.
if you interest in it,please pay it asap,thanks"

- just-intercoolers

2gnt2wrx, Yeah I saw that you did that. I took a pair of needle nose pliers and gave mine a good twist as well. I'm hesitant to turn it too much, though, seeing as how it's just plastic threads. If for some reason mine starts to drip again I'll take that nylon washer off and just use the plug and nothing else like you did.

I'd still like to know what size/pitch that plug is so I can have a bolt with crush washer for back up, if anyone knows what size it is. I don't want to pull it back off to check.

I'm not going to mess with mine unless it starts leaking, Keep us updated on how the nylon washer works because I was thinking of using one.

When I tightened it, I went finger tight then tightened it until it seated and gave it a quarter turn to a half turn.

^Good to know, that's pretty similar to how I tightened mine. I went snug and then let out a HeMan....*ROAAAAAAR* as I did it by hand to get it as tight as possible. Then I switched to pliers. Hopefully you'll stay leak free.

I wish I had seen your post before I drained/filled/burped the system 5-6 times.

Ok, so I spoke too soon. The nylon washer on the drain plug didn't work. It wasn't leaking just idling or revving, but after some driving the added pressure seemed to make it leak.

2gnt2wrx, I went with your method and just used the drain plug (I did however wrap the threads in teflon tape). I just took it for a quick drive and didn't feel or see any dripping, so I hope *knock on wood* it's good now.

Another thing I noticed is that when you drain the coolant it tends to run along the subframe and inside it. Then when you drive around a little bit the leftover coolant moves around and can make you think there is a leak (even if you think you've wiped everything down). I just kept wiping around the drain plug with a rag and then with a dry finger I would run it around where the drain plug seals and see if there was any moisture.

Hey, for someone out there who has a two cap set-up. Which cap is which on the 03+ WRX's?

Basically, if I get a new 1.4BAR cap, which one gets the upgraded cap? The one on the radiator or on the upper tank?

Ideally both should have upgraded caps. They're both part of a pressurized system.

Installed my CR racing radiator and gimmick thermostat on saturday.

Filled coolant to the top in the radiator, then filled the upper reservoir until the radiator just started to overflow the cap. Put that cap on then started the car with the upper cap still off. As it came up to temperature I would squeeze the upper rad hose and again once the fans kicked on.

Driven it about 100 miles since, no sign of air bubbles. And my heater works better again.

To anyone draining the stock radiator....the factory petcock blows and takes forever. The easiest and fastest way is to take the upper end of the lower hose off of the thermostat (make sure the engine is cold enough that the T-stat is closed, or don't) and loosen the lower end of that hose so you can rotate the hose to point downwards.

Your radiator will be empty in minutes and you can control the flow and/or stop it by how far you are rotating/bending that hose.

And since he showed up, props to ImportImage/Josh for the quick same day shipping!

And I did upgrade to the 03+ style radiator. Its one long metal pipe and two tubes from subaru. I kept the original tube and I will do a little write-up on how to use your original metal tube, a "T", and about 18" of hose and save yourself $40 if there is any interest.

+1 to import image as well! Call him for a better deal than his website can get you.

Josh, Did UPS pick up today(MLK Jr.)?
Looking forward to a new radiator, 160 F thermostat and hoses!

Update... After a couple of months o-ringlessness; Still no leak If you are not going to use an o-ring; do as I said above and check it daily. If you find there is some seepage, snug it down another 1/4 turn. Just thought I'd update this issue and let everyone know I've had success without an o-ring.

Well, since this seems to be the most "official" CXRACING Radiator thread, i figured I would share my recent install experiences.

Got the radiator in fairly good shape, a few of the fins were mashed down but nothing too bad. Overall the welds looked good. I capped the hose openings and filled it with water in the bathtub for a quick check, no leaks.

About a week later I installed it. This was fairly straightforward. Two things i noted were that the fans aren't 100% flush to each other, like someone rotated both of them about 2 degrees to the right. They still fit and function, just an annoyance. Also the bolts that hold the stock fans to the stock radiator on my 04 were a very coarse thread, these didn't work with the tapped threads on the aluminum one. I had a few metric bolts laying around that worked perfect.

I thought i would be smart, forgo the O ring that came with the radiator and make my own. I headed to home depot and picked up a rubber washer from the bolts / washers bin, 1/2" i believe. It was too wide so i trimmed it to fit the drain plug. This worked great for about 3 days then started leaking fairly bad (1/4 bottle in 15 mins of driving), I made it worse by cranking down on it. I PMed 2gnt2wrx for an update (thanks for the quick response!) and he said he had no leaks without an o-ring so i gave it a shot. Well with limited tools and hot coolant at work this really didn't work for me, i kept cranking down on it and it just kept leaking. I got to the point where i couldn't rotate it anymore with my Leatherman because of the AC lines etc. in the way. I ended up driving to the auto parts store and grabbing a new coolant drain plug from the "Help!" section. Online it said the factory one was m12x1.25 so i grabbed this one and drove back to work. After work when the coolant had cooled off a bit it attempted the plug change. Well, the one i bought was too small to thread in the opening. I was however able to stretch the new washer from this plug onto the CXRacing plug and crank it down without issue! So far, no leaks!


CN: If you want to make the drain plug fiasco easy, go get a new drain plug with gasket, swap the gasket over, and have no leaks. $4 total spent.
