No it's not that simple. Got to be careful with the K.
Plenty of info already on this site how to do it, so no point in making a lengthy reply on it.

 

I have had a look but still cant see the big problem.
Am i right in thinking that once the coolant has been drained i just refit the hose and open the bleed nipple a few turns add new coolant and once i see a nice flow of coolant without bubbles coming out of the bleed screw lock it off and top up the system.Obviously get it warm and top up as required when it gets cold.

If i am wrong with the above method can you explain why i need to be careful with the k series engine.

Dont mean to be rude but was put off by the reply and was considering taken it to the local garage but i thought i would post this again to see if i get a different reply that may make me do it myself and save on the ££££.

Thanks very much and dont be put off by me asking again.

 

I've never done it myself but due to the smaller than average pipes on the K series it's very very very easy to get airlocks in the cooling system which can cause inefficient cooling and hence HGF if not done properly. Or so I understand. Like I said it's the one job I've never risked lol

 

It is a simple enough job, well illustrated in the haynes manual. As has been said though, the K is a very sensitive engine where the coolant is concerned. Not done properly ie bleeding the cooling system and it can be disastrous.
