Ok i need to change the top radiator hose will i need to drain the radiator? im doubting it sense its so high up. thanks in advance.

 

You will lose any fluid that can find its way out, so a partial drain may be good, and have a drain pan under the car for sure! Why not take the excuse and do a full change though? Coolant isn't good forever.

 

well i just put new fluid in. I just didnt wanna deal with it thats all but ok ill just change it all.

 

just put a big catch pan under the car....when you take off the top rad hose you will only lose what is in the hose and maybe a little from the head. I wouldnt drain it at all. Especially since you just replace the coolant.

 

Yeah, you don't have to drain it all, but to keep things cleaner and make clean-up easier I would drain a good amount from the radiator drain into a bucket. Then you won't spill it everywhere when you take the hose off and you can just poor it back in from the bucket when you're done.

 

killer thanks for the helps.
