That will work nicely, just go back over it a bit later, sometimes the hose clamps release grip slightly after reheat several times and then leak a little bit. I replace all plastic parts on my earlier model doing the same trick. $80 hoses don't cut it in my world. Have a close look at where hose runs, you may need to restrain it by a hanger or such if now it's flexible enough to get near hot part like exhaust. You need good air clearance space there. Also beware of possible rubbing/chafing spots.

Ford uses plastic hose on all cars now and to get more parts sales, they justify it by saying the parts are lighter to help car get mileage. More like to keep you going to the dealer for parts that should not have broken and cannot be found elsewhere if you ask me. Or showing you how crappy they can make a car.

Welcome to the party pal...............if the remaining plastic breaks you can always solder up copper tubing like from Home Depot and those will last forever.

Hard to see it from those angles, but I think I can see it peeking out in these two areas (circled in red):



If you look vertically downward from the front of the engine bay, you can see it running from left to right before making a 90 degree bend and heading aft, disappearing under the main radiator intake hose, air intake duct and a bunch of other bundles and obstructions. There's a t-fitting that connects to a hose that I believe comes from the thermostat housing, and then the tubing continues back toward the firewall, connecting to one of the heater hoses.

Its rigid, except for the accordion bends, which is where it seems to me the weak points are. We had put about 300 miles on the car after purchasing it used before we noticed a puddle forming under the front center portion of the hood, almost right under the radiator. When then coolant was under pressure, it was showing a thin pinhole-like stream right at the seam of one of those ribbed bends. It got worse as I manipulated the tube/hose. I was thinking I'd wrap and/or epoxy seal it, but since it was right at that non-flat bend, I decided it had to be replaced.

And as I removed it, it snapped completely, so those flex corners aren't really that flexible...at least not with age. Maybe a new one is more durable. But if you do inspect it, be careful not stress those bends.

Thanks, amc49, for the advice. I've already tinkered with the setup a bit, trimming a little over an inch from the hose section between the 2nd elbow and the t-stat fitting. I just felt like it was jamming up against the fan shroud and wanted to have a little more freedom. I do think it needs to be supported midway along the front. 5/8" rubber hose is a bit heavier than that plastic tubing and, by nature, droops and can put weight on the end connectors. I'll figure something out.

I don't see any heat threats, but a sheath might not be a bad idea.

I've never worked on Fords before. I've enjoyed working on my Toyota cars and my old BMW E30. This engine is nice and clean, but sure seems like it's not arranged for easy maintenance. I probably did this the hard way. It would have been so much easier to free up that space on the right hand side of the engine. It's awfully cramped there. And frankly, the area on the left side where the belt is scares me a little. I'm going to have to get a shop manual to help me.

Even though this is a 2009, it's the newest car in the family and, I'm hoping, won't be high maintenance for awhile. Just a little disappointed to have run into this issue so soon after buying it.

I think I saw that you bought it used? If you did honestly you have no idea what could of happened, maybe the previous owner stressed it some how checking something, such as the oil. I do not think you will run into many problems with your Focus as they are generally SUPER reliable. It seems like you got a solid motor head on your shoulders so you should be set!

Thank you for pointing it out for myself, and possibly a future member that might have a similar problem. You could of just saved someone a whole lot of time. I wish you the best of luck with your car my friend, good luck! Thank you again!

Good work with that repair! And thanks for the write-up.

You may be the first to post the issue, but likely not the last, as there was a similar issue with a plastic cross pipe on earlier models (over the radiator).

Cheers!
