just noticed brown shite in radiator, ive done a search and it turns out a coolant change is in order.

 

can anyone point me out in the direction of a write up on a radator removal,

its the standard jap import (calsonic type) with a calsonic autobox cooler up front.

 

thanks

Pete

I was gonna say follow these links :- http://300zx.org.uk/tech_04.htm But I see the buggers have changed them .....

 

So try here which is where the link should go :- http://www.pexcom.com.au/z32cms/e107_plugins/content/content.php?content.267

Any reason why you want to remove it and not just flush it?

so i could flush it properly... does that sound daft?

Yep, reverse flush it, plus blow all the dead flies, leaves and kak out of the vanes too.

not daft, just thorough!!! lol

hmmm.

 

You mean from the bottom up? with a pressure washer?

 

Please divulge... :)

No, just a hose, but yes, flush it both ways, as there may be some sludge in the bottom. You can also flush the whole system whilst you're at it.

ok, any coolant/antifreeze recommendations?

The brown stuff will usually come from the corrosion of the outlet pipes from the engine, i.e. the two small pipe mounts that the short rubber hoses connect to. These are prone to corrosion. May be worth checking them if you are going to take the rad off anyway. You then just need to unbolt the water pipes unclip the rubber hoses and unbolt the mounts.

 

I've just ordered two of them and the rubber hoses from the US for under $40.

thanks guys, i will sort it weekend

if i remove the pipes where they connect to the engine, will i be able to get them back on?

I don't see why not, just be careful if it's a stock rad as the necks might snap

im actually scared now... :(

just don't force anything and you'll be fine :)

yeah the pipes come off with bolts. You'll need an alan socket and a small extention with a wrench. The lower pipe is held on by 1 alan bolt and 2 standard bolts.

 

Once you have these pipes off you will see that there are two more mounts that are bolted to the engine, these are held in by 2 standard bolts each.

 

You probably won't be able to get the small rubber pipes off of these even with the clamps removed so you may as well take them off and check inside for corrosion.

 

That's of course if you want to go down this route ;). I've currently stripped mine off and I'm repolishing the pipes , replacing the damaged hoses and the outlet mounts and repainting the cam covers :). Takes about an hour to strip everything out from start to finish.

how can you people see all this, you must have some sort of bendy eyes that can see around corners.
