Ok got a radiator and viscous fan to repair my offroad damage. Any tips on fitting/bleeding the rad?
Also how do you swap the fan?

What antifreeze is recomended, I read using the wrong one can cause damage?!

OK
Rads are easy to fit. loads of room down there. Sump guard off for more room from underneath.
To blead, personally I just jacked the front of mine up and filled slowly.
Run engine for a while to warm it up to open thr thermostat to make sure it is full.
Then take it down the by-pass and thrash it Twisted Evil

Check water level when you get back home. Keep your eye on it for a couple of days then weekly etc etc.
As for anti-freeze, I used Holts Summer Coolant. (only cause I ran out of John Deere Coolant at the farm)

Hi the viscious fans are reverse thread 36 mm and 32 mm try to use good quality fan hub spanners although a couple of mole grips will do at a push - you just have to hope that the last person didn't threadlock it Laughing

the 32 holds still and the 36 turns antiengine
cheers

I thought that the fans were 4 10mm nut and bolts in a circle? Or does that not take of the viscous unit? It's late and the whole lump is in the garage Laughing

thats right but if you remove the four bolts it aloso removes the pulley and the belt Shocked

which i found and had to slacken the belt off to get the pulley back on. the fan disconcets from the pulley by the centre bolt behind the fan. hope that helps

Ok I have done the fan the dxmedia way and was simple enough.

Got a problem with the rad though. It is identical except for 2 small pipes at the bottom inline with the bottom hose. They are aprox 10mm diameter. I am thinking perhaps this is off an auto and these are for an oil cooler running inside the casing on the cold side of the rad?? Please tell me I dont need to get another rad?!?!?

You've an auto rad - you could always just cap the pipes and save for later, or modify to work as an oil cooler??

I noticed the same on my 3.1 Rad change.
Whilst it had the Copper pipes have you tried blowing through them ? mine were sealed / blocked, so I just ignored them !
