tell me if its the transmission?

[Felipe]

89 auto trans. Ok a misty smoke rises from the air con. vents and from under the center console... kinda smells like radiator fluid... checked 4 leaks and found none that i can seeand no over heating. plus the trans kicks when going from 1st to 2nd....

if you're trans fluid is at the proper level and clean, the smoke is probably not from the transmission. the kicking is most likely the accumulator for 1-2 has a broken spring or some other valve body issue.the smoke maybe from a leaking heater core, is the coolant level dropping?if it is, turn the heater on with the car running and check for dampness in the carpet by the drivers right foot area and passengers left foot area.

i drove it with the heater on to work.... no smoke. half way i turned it off 4 a bit..and it started... i noticed that when i gave it a good rev more of it came out!!

[steve s14]

is there coolant anywhere inside the car? if so, it's probably the heater core that's leaking.maybe when the coolant is flowing through the core it doesn't leak but when it's closed off, the coolant pressure is higher and causes it to leak, i don't know.do you have any holes in the firewall or floor board area? maybe oil is leaking onto the exhaust and causing smoke to enter the passenger compartment.i'm just guessing that it's coolant because you said that the smoke smells like coolant.

When you turn the air on, you're not getting dizzy or any type of high, right? You don't want to wind up having a freon leak...

[Felipe]

nope no oil... it dosent smell burnt. it smells like the coolant and it evaporates...

im going to check on it if its the core when i get home.

i checked it out, and yeah theres some white dried stains on the carpet!!! (ok that didnt sound right...lol)

so its the heater core? what can i do about it?

[180fan]

looks like your heater core's gone busted. Time to replace it, not much else you can really do about it.

[Felipe]

any 1 selling a heater core????????

[ricebike]

try the nissan classifieds section... click here to magically go to that area now!

u can temp by pass the hoses... u don't want to be sniffing that stuff

[Felipe]

how would i go about doing that?

[ricebike]

bypassing the heater core?

ok u will see 2 heater hoses going to the firewall...

u will unclamp them then use a union joint to loop it back to each other...

then give a finger-salute to your heater core

[ricebike]

PICS!







ok, i forgot if the hose was 5/8" or 3/4"

PS: try to get a metal one ( i know that pepboys used to stock them behind the counter w/ the other hoses n shizz, but that was a loooong time ago ~ year 2000)

PPS: u may want to burp your cooling system so you won't overheat yo' engine, yo!

PPPS: how's the condition of your trans fluid... is it burnt? time to change it... my commonsense tingling says if the cooling system is overheating d/t that core leak/air bubbles... well the trans fluid is also cooled by part o' the radiator <u see those lines from transmission to radiator?>

[Felipe]

well the thing is that, it has never over heated! not even once! and fluid levels are @ full. and the transmission fluid is normal red-ish color... but them pix tell alot in how to do it.... hope i just dont truck it up!

[ricebike]

then u may wanna try to pressurize-test the cooling system 1st...

[Felipe]

test? would i need some special tools?
