Replacing Rear Coolant Hose To Turbo R33Gtst

[benl1981]

Hi guys,

There is a small 90 hose around the back of the engine that eventually leads to the turbo (coolant feed).

Have many people had any luck replacing this without removing too much.

It may just need a hose clamp as it is dropping around the old style clamp but probably better to replace the small bit of hose.

Might call around a few skyline/Nissan mechanics. Hopefully some of them have a way to do this. Bit cramped around there! Need small hands

Thanks

Im encountering this same job at the moment, you need the right tools , Ive been cutting spanners in half to get them into the tight spaces

its not a nice job to do..

Tough job to do for someone without every tool, i did that hose along with all the other coolant hoses under and around the plenum. You really need to take the plenum off to do it unfortunately if anyone else has any better ideas though....

You'll need the correct hose from nissan too

Personally i'd just do all of the hoses and clamps at the same time in 1 weekend and do it properly by taking the plenum off

Rightio. Let us know how it goes! The hose in question only has the clamps you need long nose pliers for. Hopefully one of the mechanics I call has done this before and has all the little tools.

If it's the one under the inlet plenum at the back, I've changed it without too much drama by removing the starter motor to get access

Then approach from underneath.

My shop did this job for me. A month later another hose developed a leak.

As Mystery Kid said above. Do them all

did this a while back.

Get the longest nose pliers you can buy. The ones i got must have been 9 inches long from repco.

Undo the clip where the hose goes on to the motor near the plenum and then tug the hose off (you might have to try hard, its been on for 15-20yrs..)

once this is off undo the bracket that holds the feed line as it goes down to the turbo (right near the back of the turbo/exhaust dump). With this bracket undone you should now be able to pull this whole line out from behind the rocker cover (back of the motor) as the line is flexibile enough. You will need to get the angle right though...

Once off, replace with new hose (dont need to go OEM as its just a 90 degree bend so take it down to repco and get a hose that will replicate what this one is).

When putting the hose back on to the feed nipple near the plenum make sure it isnt rusty or with sharp edges. Then otherwise put some spit on the nipple and the hose and then use ur long pliers to wiggle it on there (remember to put the hose clip onto the hose n up the right way to manipulate it before putting the hose on the nipple).

Bitch of a job but deasy enough when you know how to do it..

You can do as above and prob spend a day doing it, then wait for the next hose to leak

Or you can spend a day and a half maybe 2 and replace all hoses and clamps and not have to worry for a lot longer than you will own the car

often the toss up between getting back on the road and doing it cheaply and easily yourself and what not, vs paying/waiting big in doing all the hoses which would require a mechanic unless you had a mad tool kit, mad skills and mad patience.

My only point i make in this whole debate is for people not to put a higher pressure radiator cap on (as will often come with alot of aftermarket radiators).

This is usually the time people get alot of repetitive hose fails...
