Question Upper Radiator Hose..

Im about to go on a road trip and I was going to flush coolant and switch to an ELC but Ive run out of time. I want to change the upper radiator hose to the one that goes around the belt and Ive had it for over a month. I was going to replace it when I flushed the system. I would like to know how I would go about replacing the hose while the coolant system is still full.
Just take it off, collect what spills and put it back in the system? Is it really just simple and Im making it hard?

Thanks guys

with where it will spill from, it will get dirty - pretty much unavoidable - just buy an extra gallon (or two) of what you're using now, have a little SCA & test strips handy, and fill her back up after the swap

drain the radiator down about a gallon or so in a clean container change your hose and replace drained coolant
I strained my coolant through a coffee filter before putting it back in

I was able to drain the radiator down about half way into a bucket when I swapped the hose on my old '99 PSD. I swapped the hose and refilled with the collected antifreeze but I used a wire strainer when I refilled.

Put a 5-gallon bucket under the rad drain and drain about 4 gallons out. You should beable to take the top hose off. I have done this a few times. Then pour what you drained out back in.

I think the hardest part for me was getting the old hose off the neck of the t-stat housing. It was glued on there pretty good with all the crud. Use the screw-type hose clamps too, not the spring loaded ones that come with the hose. I'm looking into replacing my upper hose soon. It's showing some wear and tear.

I changed an upper radiator hose without draining anything and only lost about 1/2 gallon. I just disposed of the stuff that spilled out, and topped off as needed.

Which end of the hose did you take off first, Chris? Radiator side or t-stat side?

I took the radiator side off first because it came off in my hand. Plus it gave me something to help wiggle off the t-stat end.

Oh, I was assuming you were asking this Chris. HA!

I took the radiator side off first. That's the easy side to get off, and the hose will hold the coolant while you decide the best way to get it off the t-stat housing. I used a pick to help break the seal (you'll know when it's loose cause it starts to leak) then just twist the hose and pull it off.

You'll lose the coolant out of the hose, and it will overflow slowly out of the t-stat housing until you slip the new hose on, so make sure you have the other hose handy and know which end goes down.

It's simple and straight forward. All your doing is changing a hose. No need to make it any more complicated than that.

To strain the released coolant I use a paint strainer used to strain automotive paint. At least that is what I have been told that it is used for. Fits into the cone of a funnel well and isn't too restrictive while giving good filtering. Plus it won't come apart and can be reused. I have found them at auto parts stores and farm supply stores with auto parts departments.
