hi guys,

I'm after the two radiator hoses for an r33 rb25det engine.

Know anywhere in SE Melbourne that supplies it?

Also another question. I recently replaced the radiator because it died on me the other day and found that there is a bolt with a wire that attached to the original radiator (some kind of sensor, that attached to the bottom left of the radiator tank). Well I couldn't find a place to put that after getting another radiator from the wreckers as the original place where it was supposed to go was sealed. Well I've been driving without that sensor and their doesn't seem to be any problems so far but just to be on the safe side I thought I would ask.

Also how do I go abouts flushing the radiator and the coolant system? Is there a plug or screw that lets the stuff out while I run water through the top of the radiator?

And what coolant do you guys recommend. Right now I'm using concentrated coolant and mixing that with water. Is premixed better? 33% ratio? Theres just so many types.

Sorry for all the questions. :)

Thanks.

Autobarn carries most of this stuff now.

I use Nulon too.

If you have a look on the left hand side of the engine near the plenum you'll see a brass colored pipe (not the fuel rail) running up along to top of the engine (at least it is on mine) that feeds water. It has a small screw on it. If you drop the radiator fluid then refill it with the engine running and loosed the screw you'll bleed all the air out as you fill. Works a-ok for me and no air locks. You'll need to pull the bottom hose off to drop the fluid.

The 180 and gazelle both have a plastic plug right underneath on the passenger side.. of course one of them was brittle and snapped when I first got the 180.. had to pull the whole freakin radiator off and bang it upside down to get it out lol.

Luckily they are the same size :)

Here.. try this, bottom left.

yeah with that air release valve on the plenum

when do you know all the air is out

because mine just keeps bubbling light green foam out, but i never see the coolant actually come out.

And do you do this with the radiator cap on or off?

searching for radiator hose was the biggest pain for my car.

No one stocked it in the SE subs, repco, autobarn, supercheap (from Ferntree gully to Dandenong) none of those shops had any replacement.

In the end just bought a new radiator hose from Nissan Ferntree Gully. Ordered 9am morning, received 3pm same day.

But ive head from a friend, that autobarn now sell radiator hoses for $100 pair.

Flush radiator, there should be a little tap screw under the radiator and a small rubber hose. Unscrew and it should pour out.

Used Nulon 50% mix. Took ages to do and was a pain to flush the radiator.

Radiator workshops charge $30 to flush radiator (thats including coolant supplied)

Cheaper to just go with a workshop than to stuff around by your self.

Cheers

Patrick

I had radiator cap on and left the air release valve open.

I also had a shit load of white foam coming out, panicked and thought it was oil in radiator (as oil in radiator causes white foam)

The bubbling you and I saw was the new coolant reacting with the old coolant. So you didnt do a proper flush me thinks.

Look in the R33 workshop service manual for a step by step guide if you want to do it yourself

Cheers

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
