Still need a coolant bleeder tank with a larger water pump pulley?

[om3ga]

I've been planning on buying a Bleeder tank/ swirl pot for my cooling system on my sr. I recently bought a yashio factory water pump pulley and was thinking. It says that it eliminates bubbles from forming in the cooling system at high rpms.

Do you think that a bleeder tank is still necessary to get?

Im usually one to go extremely overkill on every situation, however if i can eliminate a ton of extra potential coolant leak points then why not lol.

If you do NOT know what im talking about then shucks and ill try to get a picture up.

Cavitation from the pump is not the only way to get air bubbles in your cooling system. You can still have vaporization occuring in hotspots in the engine.

Are you even having any cooling issues? If not I wouldn't even bother with a header tank and swirl pot.

[om3ga]

No im not having any cooling issues, im putting my build together and figured i might as well just do one off the bat if i was going to anyways. Right now i am going to be running a Koyo N-Flow radiator, Nismo thermostat and Yashio factory water pump pulley. I'm thinking about getting the Greddy Bleeder tank but am not sure whether i should or not haha.

i have the Greddy unit...and as long as its mounted properly (highest point in the system) it works great and makes filling the system way easier.

Really? I would put a swirl tank on every single car I own if I had them availible.

I would make the swirl tank the 1st thing on the list. Best cooling system upgrade ive ever done.

I agree.. I was surprised how hard it is to find one.. I'll probably end up making my own.. Apparently in the FSAE a bunch of schools had cooling problems because they didn't have swirl tanks incorporated in their cooling system..

Why make one when you can buy one from Poweredbymax.net

Dude that is soo cool! I love the idea, where do you tap the highest point?

[Ceepo]

Im gonna say you tap it into the bleeding nipple on the upper radiator hose neck... just remove that nut, get a nipple that threads in and run the hose?

Or you can also considered the Circuit Sports one which is very similar to the Max one above. We use breather tank on all of our cars, makes bleeding the engine alot more efficient and less chance for hot spots in the engine.

No dont get a fitting that plugs into your bleeder screw, its way too small. You can use the fitting on the upper water pipe where the TB coolant line passes through, and use the provided coolant plug on the bottom one (just below the TB).

I've seen a lot of them get threaded in to where the bleeder screw goes.

So this thing is basically raising the point of the radiator cap kind of right? So it actually becomes the highest point in the cooling system which draws air directly to it?

[drftwerks]

sard or billion.

[om3ga]

What lol???

[slider2828]

Anyone got a picture where it goes? Or the bleeder screw you guys are talking about on an SR?

Not my photo but you would attack it to the to side of the waterneck(bleeder screw for cooling system) that AN fitting is the turbo coolant return line fitting for a s14 sr20det i believe...

[om3ga]

Thats an s14 sr water neck most people use that for aftermarket coolant temp sensors. In that guys case he is using it as a coolant feed for his turbo. I dont think it would work out great to use that spot for the bleeder tank because it is lower than the bleeder screw on the top meaning air could get stuck above that hole.

Most people tap directly into where the bleeder screw goes using a nipple that is included with the bleeder tank kit. The only thing you have to buy seperately is one of those sensor connector hose tap devices that you insert between a cut hose, along with another nipple that threads into it.

[Bigsyke]

most setups just use the radiator nipple for the highest spot, thats why most kits include a cap. Air bubbles will get to the swirl tank either way, thats why you use a dummy cap on your radiator.

Alot of people still use KA's, and removing the IM for drilling and tapping a fitting just isnt practical enough.

[om3ga]

The radiator nipple is not the highest spot, the bleeder screw is higher. One of the main problems with the S13 chassis is that the radiator neck is lower than the highest coolant flow point in the head which is why you have to jack the front of the car up to make the air rise to the radiator neck.

This bleeder tank is basically like relocating your radiator neck so it becomes the highest point in the system.

Anyone try the DIF or Stance water neck adapter? Im thinking about going with this and a house coupler from PBM.

[phase2]

The passage to tap the coolant out to the radiator breather tank is not the main issue, main issue is to make sure you install the breather tank at the highest pt of the cooling system in the engine bay, best if it's alittle above the valve cover. We usually install it at the front of the engine for people using electric fans and no longer has fan shrouds with lots of engine clearance.

No, because the 1st incline will send all of the air bubbles into the tank. The bleeder screw is also no the highest point, the heater core hoses are. But thanks to the water pump the air will all end up in the swirl tank after the tstat opens up and you drive up a hill.

You install the swirl tank on the firewall, and let gravity do its job. You dont need to tap a high point because the system bleeds itself while you drive.

Interesting. Idk if im going to get one or not, it seems like a great thing to have though i daily drive my car and it sees track time as well so i guess well see, i may add one in the future but for now i may just do without it.
