Quick radiator question

[NMS1lvi4]

my radiator cracked:duh: and i need to quick swap in either a koyo or an oem one. what's the fastest u've done it? because my parent's don't want the garage taken up by my car as my sister parks there at night. oh and to anyone that know's how hard it is to put a heater assembly in do u have any advice? thanks my car is at nissan now (:eek3d: ) parents request:blah: to get checked out and i plan to put on a radiator myself since i got quoted 816 to just put in a new one. F that! as most people would have guessed,EXTREMELY overpriced. anyways if u have a radiator or heater assembly off a parts car you could sell to me that would be great thanks:bite:

all radaitors as as its the same size its easy the koyo will drop right in just undo your radaitor hoses and unbolt the top lil brackes holding it in and pull it straight up

[drifter808]

you can get it done in an hour or so. With the Koyo though it took a bit longer. Since i still have the stock fan with shroud, when the koyo is in it pushes all that forward so i had to cut down the fan alittle bit. But this is on an SR. might be different if you have KA.

Yeah if you can't manage to get radiator swap done in a few hours you've got bigger problems. It's very simple and straight forward. Just be sure you have a drain pan to catch your old coolant in, otherwise Mom will be really pissed when the dog licks it up off the garage floor and keels over!

Either bite the bullet and spend a little more to upgrade to a Koyo or just hit up the junkyard for a used one. I just put a CSF brand OEM style radiator into mine, it cost about $100 and took 20 minutes or so to install... My rad before that was like $75 from a local car-part.com junkyard.

Never done heater core in my s13...

How do you attach the electric fans to the Koyo, right now mine are attached to my stock radiator, but will swap them over once I get the Koyo installed. Never done no radiator work before, so I guess my question what is the best way to attach my electric fans to the new Koyo. Also where is the thermostat located on a red-top.

It takes 20mins and that's including lots of bsing around.
I changed mine yesterday in 10. But then again why rush?

As for koyo, they are alright for the copper one.

But as for the alloy one I'm not a big fan, for the price you pay the reliability isn't worth it.

But a fluidyne or even better yet a griffon.

The koyo is too thick, fins are too close to eachother, doesn't cool properly and, once you start to push heat soak will soon follow.

A griffon one will drop temps 30*f~ more than a koyo.

And no, I didn't read that in super street. That's from personal observations.

As for the fans, zip ties do wonders.

WTH?! man... i just did it for the first time las nite, about 9:30pm til 2am and still not done. I guess you guys are either exagerating, or crack feinds, or im slower than avg... haha. BUT, Im not stupid or retarded... so just letting the author of this post know, it could take a while.

FYI, I got a KA24de, s13, replacing a leaking rad w/ KOYO Aluminum [not the OEM replacement, much bigger]. The fan shoud wont fit, so I'll hafto trim it once I get back to work, or dump it and ziptie the hoses/wires that were on it to sumthing else that wont chop em up/melt them. I also did my Thermostat.

TIPS from a first timer:
*There's no short cut, u gotta take off everything [intake, fan shrouds, etc].
*KOYO/dual layer Rads are way fatter than stock!
*If you didn't drain the block, wash ur hands when ur cleaning the old gasket off the lower hose elbow [only remove if doing thermostat]. It was wet and I kept getting crap from my hands into the coolant
*Keep good posture cuz my back was killing me!

OK, all you veteran grease monkeys FLAME ON! hahaha, all good :]

It's not as easy as some people make it out to be if you want to do it right the first time. Take your time. Don't worry about what people say. Once you've done it once or twice it becomes easier.

The right way is to take everything apart that you need to. Anything that sticks out may puncture the new radiator when you're trying to slide it in.

Remember that the aluminium fins are very fragile. Take your time and don't damage your new radiator.

jy116...I'm curious, was this a necessary post in a 5 mo. old thread?

[jy116]

Jus incase sumone searches and it comes up. This is the tech section, so ppl might need info regardless of its age. I actually didnt even check the date because it was near the top of the list when I searched... sorry if its not allowed.

On a side note if you want just a cheap replacement I heard that the radiators sold at BAP does extremely well and is dirt cheap compared to everything else.

Just another option thats all if you want an OE like radiator.
