Hello MP  

First you have to remove the intercooler.

To do this, take off the  two  large braided pipes, Then,

unplug the electric connectors to the EGR control solenoids ( at the rear of intercooler at bulkhead)   then,

The two EGR pipes (mark these to remember which way they go on re-assembley) i always take them off at the actual EGR and thread them throught the metal loop on the rocker cover.   Then,  

Remove intercooler,  Clean it out while you are at it.  then,

Undo the tap on bottom (when Cool or Cold) of Rad, or/and Remove Top and Bottom hoses, also,  the pipe which goes to the expansion tank, then,

If it is an auto you have to undo and plug/join together the ATF  pipes in the botton of rad as well. Then,

the radiator shroud, dont know if they are all the same but mine has a corner which comes off first (on the right),  then undo the remaining bolts and jiggle the shroud  out.  Then,

Two bolts at the top of radiator and it just lifts out (not fixed at bottom)

i am sure i must have forgotten something,  someone else can help and fill in that bit   Oh yeah, there is an overflow pipe that maybe fixed but not on mine

See you when you are flush

bah , if you only want to flush it : leave in it place , remove top and bottom hoses , get a hose pipe stick it the top then in the bottom ( try to get a good seal so most of water comes out top of rad ) then repeat a few times

I had overheating problems with my 1988 Montero about eighteen months ago and 'in situ' flushing didn't work.

I removed the radiator as described in the above post and blocked off the the inlet and outlet hose connecting stubs, and through the filler I filled the radiator with diluted hydrochloric acid (Spirit of salts), this can be bought at builders merchants for cleaning cement stains from brickwork.
I left the radiator for 24 hours and carefully disposed of the acid and resultant deposits, then flushed the radiator with fresh water from a garden hose.

With the radiator re-fitted the temperature gauge stays on the normal position.

Note:- Wear rubber gloves, safety glasses and other protective clothing when using hydrochloric acid and dispose of the acid thoughtfully by thoroughly diluting it.

Hi

I just cleaned mine out on my new (to me) 20yr old Paj, the water was a nice shade of rust before, I used one of the Holts two stage flush products and flushed it through very well with clean water afterwards. I also removed the expansion tank and cleaned it out with a bottle brush so I can actually see the water line now...Refilled it with long lasting antifreeze and it is now a lovely clear pink colour. Did it about 1000 miles ago and it's still crystal clear...

Mind you I then removed the rad whilst fitting the electric fan (other post) and back flushed it, no more crud came out so the above stuff works well, have heard of people having problems with this flushing stuff but if you rinse it out well and follow the instructions then I'm sure it will be OK. It's probably a diluted form of the above acid, although it says nothing about protecting your hands....

Have also heard of people springing leaks after flushing as the crud had blocked a hole so you have to be wary of that and check the levels every day for a while, and take a peek underneath whenever you leave it parked....

Used to use Vinegar years ago Dont remember the Salt though. SOO many uses for vinegar theres a site somewhere listing them. Doubt if this is one of them though.
