Just a word to the wise. If you live in the rust belt and your Subie has reached 10 yrs old or 100k miles, I recommend replacing at least the bottom drivers side radiator hose clamps with new ones, and you might as well replace the top hose clamps too.

 

One of my lower hose clamps rusted through and snapped, the hose came loose, dumped coolant all over the road. Just lucky wife noticed it, pulled over and parked immediately without overheating.

 

I am so pleasantly stunned she listened and absorbed my imploring her to never overheat the beast!

 

My old legacy did not have a front underbody plate, rust killing loads of things on the bottom side of the engine. However my 99 impreza has a plate from front bumper to engine mount bracket I have significant less rust under in the engine bay.

Thanks for the info, will have look at them.

replace with a standard hose clamp, they are stainless and you only need to spend a few bucks, only once and it will last forever.
