Hey guys, i was wondering if yall could tell me what i would need to do to be able to replace my upper radiator hoes. The reason i am replacing it is because it is leaking. I was wondering if i need to drain my fluid before replacing it. i would also like to know where it is located and what would be the easiest way to get to it. I have search some threads looking for a DIY but i could not find anything. So any help would be appreciated.

Thanks, Clayton

You can find all the information you need in DIY and Service Manual.

Its not hard actually, u just need some time.

First thing u need to do is to take the battery box out completely. You dont have to drain your fluid at all, but why not ?

After the battery box is out, u should have a *clear* path. but becareful with the upper hose thats connected to the Radiator. When u try to take that out, MAKE SURE you will be careful 100%, if u force it too much it might break the plastic part of the rad and u'll be screwed. (I broke mine, but I was replacing my radiator so it doesnt matter)

To build on what nycgps is saying...

The upper hose is actually two hoses with a metal coupler in between, so assuming the one connected to the radiator is the bad one...

1.) drain the radiator fluid
2.) pull out your battery
3.) pull the lower part of the battery tray
4.) Get a bunch of towels ready to catch all the radiator fluid that's going to come out.
5.)Pull out your overflow tank (taking this off will make it alot easier to get to your upper radiator hose mount on the radiator)
6.) pull off the end at the metal coupler first (because it's more accessible). I find that a very small screwdriver works well at breaking the seal of the old hose. Then twisting and pulling works good.
7.) twist and pull the radiator end off next. This end is more tricky because it's way harder to get to, but now that the whole hose is loose you can move it around and bend it.
8.) I'm not sure if you're using more oem hoses or going to pick up some silicone hoses but since I've written this much but why not write a little more. I installed Agency Power hoses on mine and they were very slightly smaller than stock so they were a b**** to get on. I ended up stealing some of the wife's crisco on a butter knife and putting a very light coat with my finger onto the lip of the hose mounts. Obviously not where it would get into the coolant at all but just to help get the hose over that widest part. I found that putting the hose on at an angle so part of the hose is over the lip of the mount and part is not, then in one motion, twisting/pushing and straightening the way I was holding the hose vs. the mount got the hose on pretty fast. Don't know if that's understandable or will be needed but it might save you a little frustration.
9.) reassemble in reverse order, refill your fluid, reconnect your battery, enjoy idle problems

I replaced mine... I only posted a few of the pics I took though. Given how simple it is, I don't think a DIY is needed.

Sorry, just had to jump in and say I really hope I don't have any upper radiator hoes. My girlfriend would kill me if she saw 'em.

And now, back to your regularly scheduled topic.
