auto radiator on manual car

[madness410]

I'm on the last steps of installing a new cooling set up on my 87 iroc. I have a rad thats made for an auto car...I have a manual car. will it leakfrom where the trans cooler line is supposed to go? thanks for any help in advance.

[LTb1ow]

It shouldn't, if its like mine, the tranny fluid is a separate part of the rad and if you don't use it, it just stays empty..

[sweetbmxrider]

no, it won't

[madness410]

is there anyway to test it before putting it in? id hate to fill the rad up just to take it out the next day because it leaks. i put a garden hose in it for a little bit and a little leaked out the hole

[sweetbmxrider]

its completely separate. you think people want tranny fluid mixing with their antifreeze? come on now! if something is leaking, its not because you don't have tranny lines hooked up. you can plug the fittings if you see fit. be it bolts or capped nuts or whatever. it won't affect anything though!

[LTb1ow]

Yea but the tranny cooler cools tranny fluid, they are separate from coolant... so you may have a leak in your rad.

[sweetbmxrider]

yeah i meant to say that but rambled. if you see water coming out of the tranny fittings, get a new radiator.

[madness410]

i will see how it plays out maybe my eyes were lieng to me.

[NastyEllEssWon]

sounds like its rusted inside

Yup. Should be a seperate circuit. How new is the radiator?

i bought it off of 88irocvert...not sure how old it is, it doesnt look too bad

[ZeroCool8891]

the rad is brand new was in a car for a few hundred miles, took it out the car to do a griffin rad setup, never had a prob, and the car was also stick.

[madness410]

yeah it definitely leaks out of the bottom of the radiator where the trans cooler lines go. i need to get a new radiator then

[LTb1ow]

You sure they are tranny line hook ups? Could be something else.

[madness410]

could be..i just assumed they were because i heard that the rad was off an auto car. the holes it is leaking out from are holes under the bottom hose

[sweetbmxrider]

can you take a pic? sure it isn't the petcock, the radiator "drain plug" justtttt askin!

[madness410]

it could be...im pretty sure i remember 88irocvert saying it was an automatic radiator. it very well could be but it didnt come with plugs or anything for those holes

[sweetbmxrider]

well if its two holes and they are somewhat apart, its probably for tranny lines. a cell phone pic with a flash light will work fine

Stock type 3rd gen radiator:

The two holes on the right side with the brass looking fittings are for the trans lines. The white / silver hole on the very bottom right is the drain petcock.

Which is yours leaking from?

dam i really wish i could snap a pic but its dark and raining out.

justin thanks for the pic...its definately one of the ones under the lower radiator hose. i know for a fact if it is the bottom one it wasnt a plug like that and was just an open hole. i remember there was also an outlet on the side of the radiator leading to another one of the holes. really hard to describe i will snap a pic tomorrow.

[madness410]

..my hair will get all frizzy

[LTb1ow]

Sigh.


I have no words.

Pics tmmr or GTFO.

[madness410]

i was just kidding. i just went outside and took some crappy pictures. im almost 100% postitive its the drain petcock...i didnt get a plug for it when i got it. i will take the rad out tomorrow to make sure, and get better pics then. until then anyone know where i can find a plug?

[Tru2Chevy]

I would say to start in the HELP section of the local parts stores - not sure of the size though. You could also grab one from a junkyard or ask here if anyone has a junk radiator that they are willing to give you the plug from.

[madness410]

ok it was the drain plug. i headed to advanced and they had one in stock. thanks for all the help everyone i appreciate it.
