Drain pan (that will fit under the car), mop/sponge etc. to clean up the mess when you drain it

to go along with what larry said... for god's sake, keep the animals away from the coolant!!

a buddy ended up spending an extra GRAND to save his puppy while swapping radiators. talk about hidden costs!

OEM hose clamps might be too small ont he SMP radiator side. I had to get slightly bigger ones. Then again, I had Perrin rad hoses.

Water Wetter or other coolant enhancer
Subaru Cooling System Conditioner ~$1 from your dealer. It is required by your car
You will probably need more coolant/distilled water as those bigger radiators need more fluid. I'd make it 2 gallons of each to be safe.

very large section of cardboard...

Just in case.

Oh, and take off that plastic shield up front, or coolant will hit it and drip all over the place.

Default i just swapped last saturday...

swapped for PWR, boy was it every easier than i expected it to be...

biggest pita about it is draining and refilling...

thanks for the heads up on the conditioner from subaru... might i ask what it is and what it does... wait lemma guess... i know i know.... go read the faq on radiator swaps... i read some of it, guess i didn't get to the conditioner part REQUIRED for your car...

noticed this... so just don't be dumb like me... at end of install, i spun the fan blades with my finger to make sure nothing was restricting their movement or in the way after the installation, just a precautinary measure... well i got my other finger in the darn way and i'll tell ya what... those freakin' things are sharp... slashed me open good on the top of the finger that got in the way... darn thing.

anyone running as much as 75% distilled water in the warmer months... is this effective for better cooling? plus the water wetter...

oh yeah... i thought i read the SMC was very similar to the PWR.... if so... i had no probs with the oem clamp size on the PWR with Perrin silicon hoses... so skip buying a whole other set if you haven't already... i had plenty of room to move with them... the rusted originals however can break pretty easy when loosening and tightening.

fillup is easier with a funnel or course, but that goes w/out saying i would think.

More water = better. More water in the winter = more frozen.

The conditioner is an English additive that lubes the seals. It is now required on ALL Subarus with every coolant swap. This will hopefully keep your car from having the leaky head gaskets that befell many of the RSs in the late 90s/early 00s.

Default thank you..

so if i talk to the service dept, they should understand when i say i need 'subaru cooling system conditioner'

sorry... out here in OH the dealers and service depts don't seem too knowledgable about this stuff...

one time when i mentioned "tumble generator valve stuck open" to them... they all looked at me like I had 3 heads and replied, 'what the heck's a tumble generator valve' ....

it was quite amusing, and a bit disappointing... from there i went home and yanked the darn things out myself... nobody cares about my car as much as i do is what i figured.

Yeah, it's a little blue bottle roughly the size of a deck of playing cards. More info and a pic of it

Default just be careful

some oem coolants do not cooperate with water wetter....

they can turn into gel and clog up your core...we found that out the hard way on the audi and vw's...

Im a big advocate of water wetter because of racing, but some dont cooperate...the biggest benefit of water wetter is to run it with plain distilled water (as we do in our water/air) except when its cold out...

if you are in an "above freezing" climate...I'd keep the coolant to a minimum and run just dist. water and wetter...

my 2 cents...

From what it sounds like in the info you just provided all cars necessitating this coolant conditioner would have received a notification. Did I read something wrong? I have never heard of this until now. Do I need to worry about now or should I just wait to put it in with my next coolant flush?

I'd add it now. Suck some coolant out with a hose/turkey baster and pour it in. I think the bottle only holds 4 ounces so it's not a lot. Pour it in and go for a 20 minutes drive to circulate. Remember this info and pass it along, it's not commonly known.

Subaru has determined that certain 1999 through 2002 model year 2.5L equipped Subaru vehicles may experience an external coolant leak from the cylinder head gaskets.

Countermeasures applied to the manufacturing process for those 2002 and later VINS not affected by this campaign have eliminated the need for this campaign to be performed on those vehicles.
I'll ask about it, but I'm not sold yet.

a) I don't have a 1999-2002 2.5 block
b) I have a 2002

I'll speak to Mastro Subaru, the local service dept here.

And I would like to point out that this is the only coolant that touched the ground (splash when removing lower coolant hose). It was very easy to not make a mess, actually.

Thanks for the advice.
