Warning, or tip, for those changing coolant hoses

Post by jas88 » Mon Jan 30, 2012 8:13 am

I have been collecting hoses for my FS for a couple of weeks, getting them from RockAuto, and so yesterday I started replacing. Here is the deal - there are SEVEN radiator hoses on this thing, and I don't even have rear heat. Unfortunately, in looking under the hood and on RockAuto, I only identifed and bought 6 of 'em. The tricky one is not easily found under the hood or on RockAuto because it is listed in a seperate section and is called a "bypass hose". Well it is NOT a bypass hose, it's the main feed from the block to the water pump. It's GATES part number 23009 and nobody in town has it, so my FS is down until tomorrow.

So, if you are gonna replace your hoses yourself, make sure you start out with SEVEN radiator hoses and 2 heater hoses if you don't have rear heat. If you've got rear heat, maybe you could tell us how many total hoses you have?

Thanks, that's good to know.

I'd be interested in your thoughts of the condition of the hoses, and after removing them if you thought is was worthwhile? I figured this may be a good thing to do @ 150K, but I live in mild temps (Seattle) and the hoses still seem like new. I was thinking that 200K or 10 years, whichever comes first, would be a good interval.

I do have rear heat (the dog is a big fan of this, BTW), so I'll post the info when I investigate it a little more.

I thought all the hoses were in pretty good shape. They were all pliable, but not too soft. I was stretching on this myself, I normally change them at 100K, but 150K seemed fine. I am letting my 2005 Escape go until 150K as well. Like with everything automotive, YMMV.

Thanks for the information. I had no idea there were so many different coolant hoses on this vehicle. The parts catalogs are very confusing and I think it would be a worthwhile project to list the various hoses, FORD part numbers and Gates or Motorcraft part numbers.

FORD PART DESCRIPTION MOTORCRAFT
NUMBER PART NUMBERS

8333 Upper radiator hose

8A319 Lower radiator hose

8A577 Coolant pump hose

8A507 Thermostatic housing to
bypass tube hose
8063 Degas bottle to thermostatic
housing hose
9F814 Thermostatic body to
thermostatic housing hose
18663 Heater hose

8B298 Lower radiator to thermostat
housing hose.


I would greatly appreciate it if anyone with the information would
contribute the missing Motorcraft or Gates part numbers. This would make ordering replacement parts a lot more simple for all concerned.

Thanks,
Ken H.

Here are all the hoses I used:

Dayco 87895 Heater Hose
Dayco 87896 Heater Hose
Dayco 88458 Heater Hose
Dayco 72289 Radiator Upper Hose
Goodyear 62768 Radiator Lower Hose
Goodyear 62480 Radiator Lower Hose
Goodyear 62333 Radiator Lower Hose
Goodyear 62767 Radiator Upper Hose
Gates 23009 Bypass Hose (this is the one I was missing)

I bought Goodyear when I had a choice but the Dayco and Gates hoses were not available in Goodyear from RockAuto.

As always thanks for the knowledge - to all of you!

Which of the hoses listed are the 2 that heat the PVC valve that is just behind and on top of the throttle body intake?

By the way I live outside of Chicago and haven't changed my yet either.

Thermostat once yes, water pump once yes, hoses not yet.

One side is included with 87895 Dayco. The other side I did not replace.

It would probably be a benefit to all if
there was a list of FORD part numbers for all these
various hoses and the corresponding stock
number for the replacement along with a description.

This is more of a job than it looks as the descriptions
of the hoses do not correspond for the most part with
that of the catalog items from the various suppliers. The
descriptions are very misleading and hard to follow.

Does anyone have this information ? Thanks.

Ken H.

As an example:

Ford Part Number 8A507 Replacement Gates 23009
Ford: Thermostat Housing to bypass tube hose.
Rockauto: Engine to water pump 1 - 1/4" x 11 5/16".

The PCV hose that goes to PCV itself is KCV160, or KCV161 if you have a heated PCV. I changed this when I did my plugs. The hose seemed pretty soft, and given its location buried behind the IM, that's not surprising. Since the plugs are a 100K item, it's probably not a bad idea to change it with the plugs. At a minimum, I'd take it off and clean it.

One guess on my part is that the lower coolant temps on this car results in the hoses lasting a lot longer. By 100K, the hoses on my past euro cars were always pretty ragged--but coolant temps in those cars were consistently in the 100C range. Coolant temps on this car are normally 84-90C, about 5C less than my Volvos and VW's. This is weird to me, since it supposedly comes with a 90C thermostat, but I almost never see coolant temps over 90C? Regardless, the hoses seem to hold up pretty well, and judging by the reports on this forum the entire cooling system seems pretty robust. This is a nice departure for me, since euro cooling systems seem to require radiator and heater core replacements as "maintenance items"...

So the wife drives the FS for one day with all the new hoses and such on it and the water pump goes out! Leaking all my brand new anti-freeze. Anyway, ordered the WP, got it last night, it came with a new 23009 hose attached! Dangit, that would have saved me $25. So now I have an extra I'll never use. I wonder if my Escape has that hose? The good news is the WP is super easy to change out, had it running again in about an hour, FS is back on the job today.

I need to learn to not use the word "never". "Never" is a long time. I saved the 23009 hose and now it's time (150K miles) to change the hoses on FS2. I will get to use that extra 23009 hose after all.

I was able to do the job this time around with more Goodyear hoses, which are now labeled "Continental Elite". I am documenting the list here for posterity and for me, next time:

Edit: I got a case of brain-dead and forgot that FS1 did not have rear heat, but FS2 does. So I had to swap the hoses that are different. Natch they did not have those in CE so had to take Dayco, kind of like last time. Harumph!

Dayco 87913 Heater Hose (CE 64359 w/o Rear Heat)
Dayco 87912 Heater Hose (CE 64656 w/o Rear Heat)
CE 62334 Heater Hose
Dayco 72335 Radiator Upper Hose (CE 62335 w/o Rear Heat)
CE 62767 Radiator Upper Hose
CE 62768 Radiator Lower Hose
CE 62480 Radiator Lower Hose
CE 62333 Radiator Lower Hose
Gates 23009 Bypass Hose (this is the one I had leftover from last time)
Gates 18195 Reservoir Hose x 2

That last one (Gates 18195) goes from the water pump all the way over to the coolant reservoir. I was not able to find the hose that is the other half of the equation for the EGR, so I bought an extra 18195, which is the same diameter but much longer, and made one out of that.

Anyone know what the horizontal T-shaped metal coolant tube is called, located behind radiator on bottom? Lower hoses attach to either side of it, and something like a flex tube coming up from the tee... This tube--obviously made of steel--rusted through, puking the coolant out. Overheated, and left me/family stranded. Need to replace that tube, but I've been banging my head trying to find out what it's called! Please help.

Absolutely head to Ford and to the parts counter and get your part. They can tell you the name of it. 8)
