Coolant change advice

Hello i'm thinking of doing a coolant change can any body advise me of the best pipes to take of for drain down and what is the capacity of the system i think mine will be a bit more than normal i have extra lines to a coolant powered water heater for taps etc under a rear seat think its callled a calorifier? thanks john ps its a 2.8

Normal capacity...somewhere around 9.5 litres.
THeres a drain screw at the bottom left front of the rad........which pipes?...whatever you can get hold of....I just did the top hose / thremostat housing off and the rad drain....then various other sections on a whim for flushing.
I'd guess there are some block drains...if you can reach them........
Main thing is to refill slowly....don't want any air locks in there.
Use something over the rad cap to extend its height if you like...(clamp the tube going to the expansion tank)....so after the fill you can let the engine run and any air bleed up the tube.
I used an old drilled out rad cap...spare fuel pipe roughly fabricated to top of the cap leading to a bottle suspended from the raised engine cover. Don't know if this extreme is necessary...but it made me feel better!

Another thought......
Maybe use the red antifreeze (with the fluoroescent dye in).
It shows up really well with a UV flashlight
Keep a cheap UV flashlight in the glove box and it may help with a speedy diagnosis one day.....+ you'll be amazed how many fillings you have in your mouth
