Radiator Cap
Radiator Cap
I lost my stock cap awhile back and bought a $6 one from Kraken's Auto.
Then I've replaced it with a Nismo one. My water temp actually went down about 5 degrees. The quality is pretty cheap though. No better than the $6 one. Arc ones are actually much nicer.
stocks ones are rated at .9 bar (not positive).
nismo is rated at 1.3
I paid like $40 otd from the dealer.
It feels like you have a rotate a bit more to lock in place than the stock ones.
I have a Stillen radiator.

I just posted this since rad caps aren't covered too often here.. trying to get some feedback you ******.
wow, another scientific study on how a radiator cap causes lower temps.
They aren't related. The only thing that can ever lower radiator temps is more cooling at the radiator itself.
adding a different cap only pressurizes the system more which will allow you to have higher temps without boiling the coolant. It WILL NOT alter the cooling abilities of the radiator.

man, i type reeealy fast, ..btw... thats why i always have so many typos.
I just never really care to correct them.
nah i dont get why either, but yes a radiator cap seems to offer such an upgrade to cooling on a routine basis. I think everyone has just had a tuff week this week, dont know about yal, but im frikin beat. Ive flown from the west to the east coast and back from a monday to a friday every week for the past few, and have a few more to go.. that will mind fawk you like you cant believe.
I also think im gna spring for the pathfinder mod while my engines in pieces.
Sir, take that wig and tiara wearing princess cat off before calling names. haha. jk.

technically, it should go up if anything, but mine went down. normal operating temp stood exactly the same since I've changed out my thermostat and keeping an eye on the water temp. drove a few days with the new rad cap and it's at 4-5 deg cooler consistently. No change in the weather for about 2 weeks now.

That's the reason everyone is making fun of you. Radiator cap only allows for higher pressures which causes the boiling point of a liquid to be increased therefore when race cars that have no ethylene glycol in them to allow for higher boiling point they wont boil over at a mere 212*. So they can run straight water with higher pressures and get a 250-260* coolant temps without boiling and cavitation and without using any additives that are banned on tracks.
I have been building race bikes for over 10 years now and have a minor in physics. I, along with everyone else here, knows that a radiator cap has absolutely nothing to do with temps of a radiator.

thanks homie, i appreciate that.

lol, if the car wasn't overheating then the rad cap would not have an affect on it.
It's not coming from my mouth, it's the laws of physics. Tell the laws of physics that "it just happened" on only your car this one time and i'm sure the world will change around you.

oh so now you change your story..
so you put a 20lbs rad cap on a non turbo and you don't think it will affect the coolant? So it doesn't affect the coolant behavior (the pace the water boils) whether it's a 3psi cap or a 30psi when you're tracking the car? I guess it doesn't really matter at higher elevation either, since the two have nothing to do with each other.

50/50 glycol and water is about 248* boiling point with a standard .9 bar radiator cap.
so, i'm seeing MAX 212* radiator temps with my 523hp turbo car. Putting a larger pressure cap on it will raise the boiling point to say 270*. Great, that does nothing for me since i'm not even boiling my coolant to begin with.
the only way it will affect anything is if you are boiling your coolant already. If you are hitting 248* radiator temps then you have more to worry about then if it's boiling or not. So, like i said before, it will do zero. And also, no matter what it will NEVER affect the cooling capacity. Pressure only alters the boiling point. That's it.
you have a lot of reading to do on physics. Throwing around random "i know this works even though it's completely against physics" in these forums will get you flamed fast. The members around here are very intelligent and don't put up with honda forums type stuff going on.

where do you come up with this stuff?I've replaced my radiator cap twice on my mishimoto radiator, I didnt notice a drop in my coolant temp but it stopped the coolant leak. I'll try anything to keep my coolant temps down, I even put a bottle of the redline water wetter stuff. Does it help, dunno but im sure it can't hurt.
If you have a Mishimoto radiator cap then their radiator caps SHOULD be under warranty.

A higher pressure cap raises the boiling temperature of the liquid being pressuirzed. It allows the coolant/water mixture to reach a higher peak temp before being released to the overflow
It will not and cannot lower your coolant temps by itself.

Wish I was here earlier, but every single thing that binder is saying is somehow slightly righter than the last thing he said!! It's thermodynamics and heat transfer and these are particularly well understood areas of science. If you are noticing lower temps, there IS a reason and if you search harder than a religious prophet, you will find that it is not the cap. In fact, an inaccurate thermometer or inconsistent testing method would be the first place I'd look.
I think you are confusing over-heating with boiling over, which isn't technically the same (although it's a bit of a love/marriage relationship.)
