Okay so one morning I decided to check my coolant tank just becuz.....and I noticed it was alot lower than usual.....I thought that was weird so I just added disstilled water and brought it back to spec.....then I tore apart my stock airbox to install my BERK/APEX-I and found this.....



See the red coolant on those hoses? Can anybody identify this hose? I have no idea where this leads to....and do any other 2k2 owners have this problem too? Btw this is near the tranny area right below the BERK midpipe area.....someone please identify this hose for me so I can replace it and how much this part will cost...Thanks!

 

Not sure what it is because I can't see where it goes to. If it terminates into the firewall then it should be a heater hose. Without having my engine bay in front of me for reference, typically, you have 4 main hoses: Upper Radiator, Lower Radiator, Heater In and Heater Out. Someone who has messed around with the hoses before will have to keep me straight.

 

That looks like the tranny breather hose. It belongs like that.

 

That is your heater hose

 

Oh and you shoud not use distilled water in your coolant.

 

thats the tranny breather hose and it belongs there

and thats not coolant (which is green) that is tranny fluid based on the red color and the location

 

Then what should I use?

 

No u guys have it all mixed up....that is my COOLANT becuz I changed my coolant to TOYOTA REDS....not NISSAN GREENS (factory coolant)

and No its nothing related to the transmission becuz my tranny fluid looks brownish,black just like engine oil.....

The hose i'm talkin bout is in the middle of the picture, not where my hand is at.....can u see the red fluid on those two hoses? For reference this pic is located near the transmission/intake area (drivers side).....are they really the heater hoses?

 

Tap water and yes it is your heater hose

 

Tap water huh? From what I learned in automotive class tap water contains many different particles/minerals that could contaminate the radiator system....and disstilled water is pure H20 which has no minerals or particles except h20, making it safe to run in the radiator....correct me if i am wrong...

 

didnt realize you were a 6-speed..and thought you were talking about the hose in your hand.

yes those are heater hoses. wash off the coolant and look to see if there is a crack in the hose somehwere

 

nissan recommends tap water

are you sure the new coolant is compatible with a nissan cooling system??

 

Sorry, I also thought you were talking about the hose in your hand.

 

Yes I am sure its compatible....Theres a whole article on it in the FLUIDS & LUBRICANT section on the .org.......

And if Nissan Recommends tap water.....what is so wrong about running disstilled? Not enuff minerals or something? From what I learned, its not good to be running all that crud inside your radiator system....

btw thanks for all your inputs!

 

I guess I should say you dont have to use distilled water. My thoughts are,
distilled water is acidic, not neutral. The problem is that distillation in increases the ionic content of water by removing the disolved salts and impurities. Although stilll very dilute, distillation frees up more hydroxide and hydronium ions that would normally be bound to these disolved salts in less "pure" water. This makes distilled water more corrosive than say, "bottled" water at the grocery store.

I dont think it really matters. I have never had a problem using tap water.

 

Thanks for clearing that up!

 

and No its nothing related to the transmission becuz my tranny fluid looks brownish,black just like engine oil.....


You should really change your trans fluid if it looks like your oil...

 

My service manual says to use "demineralized water/distilled water" in the cooling system. I have never seen any documentation in any service manual that says use tap water.

 

Since when did plain old water have an acidic pH? I think you need to review your high school chemistry. The definition of a pH of 7, or completely neutral, is plain old, distilled water. What makes a liquid acidic or basic is the concentration of hydrogen ions to hydroxide ions. Distilled water has an equal number of each, giving you a neutral pH. Besides, when mixed with equal parts of antifreeze, which contains salts, that should take care of any of the issues with free ions. Hence the recommendation of running a 50/50 mixture of water and antifreeze. It's not only for the extended liquid temperature range. I don't know what your water is like, but if you live somewhere like Wisconsin, you will have a ton of iron and calcium in the water. Very bad for your cooling system. Do a little more thinking about what you are saying. A little knowledge is dangerous.

 

I run Deionized water in the cooling system, and guess what.......Its just fine. In fact, no sediment at all. I know its not quite the same as distilled water, but there is no harm in using it.

 

This is incorrect. Depending on your local tap water quality, tap water can and usually does contain minerals and other junk that can cause corrosion in the cooling system. Only use distilled water.

 

SALT corrodes aluminum! It is good if, as you say, the salt is removed during distillation.
Distilled water is PURE water..... without extra junk dissolved in it.

 

Sorry, I just don't like to see disinformation posted in a way that makes it sound like scientific fact....

 

Apologies.... I have edited the message.

 

and i have always used tap water. including the three times i have done a complete flush. i have never had a problem.
