On a cylinder head removal, do you have to drain the coolant
Discussion
The Haynes manual is telling me to drain the coolant, however its only instruction is 'remove the hose from the left of the radiator'.
There's no diagram, no picture, no in depth location for this, it doesnt even say left as you look to the car or left as youre sat in it.
I cant find the elusive hose anywhere, does it make a difference if it is not drained off?

Best to drain it, otherwise you'll end up contaminating the oilways with water as you remove the head and it'll go in the cylinders.
ETA: If you drain it carefully you'll be able to put it back in. Also, if you spill any (and you will), be sure to hose the area down when you've finished - it's poisonous to animals.

Just remove the bottom large rad hose which ever side it is on.

If you don't, it will result in something that looks a little bit like this:does it make a difference if it is not drained off?

A bit of a PITA to clean up, to be honest.

You're removing the cylinder head but you don't know how to drain the coolant? Left and right always refer to facing the direction of travel in haynes manuals.
I was about to say...In my mind a HG replacement is quite a tricky job - are you sure you are ready to attempt it? (No disrespect intended, just for your sanity and the car engines sake!)

This is what concerns me! why are you removing the head and if you are doing an hg change then are you goin to getthe head checked or just risk it?I share the same concerns as voiced by many, I did actually check the Calendar to make sure it was Christmas and not April 1st.
However, everyone has to start sometime.
May I suggest, lots of pics with your digi camera. Start with it on number one. Do not move the crank/pistons do not mess with head. Take it off/put it back.
I usually hit the solonoid to pop a head after the bolts are out, someone may suggest that, don't do it. Keep everything aligned.
You are going to need a torque wrench !
We are going to take the pee, but you will get help.
Good luck.

I'd collect the coolant anyway - It'll freeze this evening if it goes on the driveway, which won't be fun.
? I'd have thought it wouldn't freeze. It shouldn't anyway!Good luck OP. I was thinking about starting the timing belt change earlier, but the thought of the looks I would receive from the neighbours (already think I'm a bit car mad, to say the least) and the scotch I got earlier made me think twice. Tomorrow it is then!
