Ok so i did some search on what i need some tips on and found little bit here and there but not really convinced yet.

Heres my situation.... Ok i have sr redtop in my s13. I was in the freeway and noticed temp needle all the way up to high aka overheating. So i found out one of the cooling hoses underneath intake manifold ripped. I know its gona be a bitch to get to this hose so im thinking of just removing the whole intake. Now couple of Q's here:

1. can i get to the hoses from underneath the car to replace these without removing parts?

2. Can i just remove the upper piece of the manifold to get to the hoses?

3. Is it alot of work taking the whole manifold out? What gaskets am i gona have to replace?

I've always worked on my cars so i have some kind of mechanic knowledge, how much of a challenge is this gona be? Any input or tips would help guys.

Take off the whole manifold its not hard
Pull the injectors some vacum lines blah blah

Just mark where everything goes and bag and tag all nuts and bolts where they go

Just to help you out heres what your gonna be looking at

The Manifold>Head gasket is a metal gasket so you might get away with resusing it. But I wouldnt just so you wont have to ripp it off again to replace it.

manifold is not hard to get off and put back on at all. iirc 7 12mm bolts connect to the head, 5 12mm bolt connect the upper part to lower part loosen the and pull the upper manifold off after unhooking 3 gas lines. there might be a few misc support bolt to cant remember just remove them. Lower mani is held on by a manifold support that has 2 12mm bolts on the bottom and 1 or 2 near the front iirc. Once you get them loose just lift the manifold up, no need to disconnect and hoses and replace the one you need.

Thanks for all the input guys, now i feel more confident to do this. By the way what does iirc stand for or what is it?

i changed all the lines and installed a block off plug on the 1 inch waterneck , with the manifold on and engine in the car, its not too bad, i pushed my left hand through the left side of the manifold where its open (the side facing the firewall) give it a decent try with the manifold on, i thought it was going to be a nightmare but in the end it was pleasantly easy

zylvia213

Yea ill give it a try before taking the manifold off. Now does anyone know the torque specs for the bolts that connect the intake manifold to the head???

2 step process. all bolts to 8ft-lbs, then 20 ft-lbs. of course starting in the center.


as far as the gasket, there are plastic "thermal" gaskets that supposedly reduce heat transfer and also serve to increase air volume... circuit sports i believe makes them. they are also re-usable which is why i bought one.

n240sxfnatic

fsm manual has it as one step 13-15 ft lbs

aNskY

uhhhhh, no... where do you think i got that info?

n240sxfnatic

ummm I know where I got it, the fsm in front of me, its an s14 sr but torque spec are said to be the same

singlecamslam

good read, shouldnt be too hard. i have to take mine off to get to the IACV unless there's some other way, also i wanna take it off to clean all the shit off.

Thanks again guys....as for the gasket well i just picked one up today at superior nissan OEM. I did see that circuit sports gasket that you talk of... is the OEM one reuseable aswell??

Well guys i replaced the hoses today..... i got to honestly say its not that bad. Taking intake off was no biggy. Took me a good 1/2 day to do this but it was fun i guess. I did hear from a few guys that there is no need to take intake off to replace these hoses.....well the truth is i think you have to. There is no way you can get to these without taking it off unless you have some small ass hands and shit. For anyone out there that will be doing this, just remove intake, its much easier and it guarantees the job well done. Thanks alot guys for the input on this.

you are correct
