Engine/Transmission (1998.5 - 2002) Radiator Hose Replacement

[wlowe]

So how hard is it to change the radiator hoses on a 2001. The top hose looks fairly easy if it's not welded to the connection. The bottom hose looks a little harder, not much clearance. My radiator drain isn't working very well so I'm thinkin of cutting the bottom hose to drain it. Also, the radiator is made of plastic on the sides, anybody break or crack the radiator when twisting off the hoses? Any tricks to getting the hoses off easy, best tools to use? All help is appreciated!

Use a hose pick, deal that you can get at auto part store, 90 degree from the handle. get it in between rubber and plastic to break them free. Use coolant to lube inside of new hose, and they will slip on easier.

The bottom one can be tougher to get off, but if you're going to replace it then simply cut if off and let everything drain out completely. Then use a small screwdriver or ice pick to get under the hose surface and break the hose loose from the radiator. Then it will be easier to get off. They make fancy hook like tools for just this job but thats only if you want to save the hose.

I just replaced mine.
The hardest part was the spring clamp on the bottom hose. I think they make a special pliers for this clamp but I don't have a set.
I cut the bottom hose and was finally able to get the clamp off.
On the other install I used regular screw type hose clamps.
Are you sure your drain isn't working? I thought thought mine was plugged but you have to turn it ccw and pull it out as you turn it. It will pull all the way out for a faster drain.

I understand that screw type hose clamps are easier to work with, but there is an important benefit to a spring clamp. A spring clamp behaves like a "constant torque" clamp and self adjusts for thermal expansion / contraction and vibration.

Screw type hose clamps can lose their clamping force under certain conditions resulting in small intermittent leaks. Additional tightening of the screw clamp can result in damaging the hose.

I believe the use of spring clamps will maximize the life of a hose and minimize the likelihood of a leak.
