Radiator Hose

[chopobo]

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.

There's usually a plug underneath.

We use the Nulon 3yr long life coolant.. hmm can't remember the ratio.. maybe 50%

You can take the old hoses to pirtek, HIS Hose or Repco and try for a match

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.

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

Yep foam is normal, I too crapped myself when I saw it. You should know it's right to go once the water squirts out. Yep you'll need the cap off to fill it
