So... I'm going to do a write-up with part numbers and stuff on what interchanges between the years of 95-01 for the Blue Hoses in my page, but in the mean time, I wanted to show the difference between the quality / reliability of the normal hoses, and the blue silicone hoses.


Here are two of the hoses installed in my 02 CV LX, only the main one, and the overflow... hah. I'm going to do the rest, just haven't gotten around to it:




And here is the difference between a factory OEM black rubber hose, and a factory OEM silicone hose:







So, to put into perspective:

The factory BLACK hose is from the 2002 (original), it has the original clamps, has only been removed once before, the vehicle ONLY had 49k miles on it when removed, and the vehicle spent the vast majority of its life in a semi-climate controlled garage. Temperatures were always kept between 50-85 degrees.

The factory BLUE hose is from a 2006, I assume they are the original clamps, and the vehicle had ~110,000 miles on it (wrecked). I can only assume as it was a police vehicle (North Miami Beach PD) that it saw lots of hard time in South Florida and probably has a lot of idle hours.


The difference is night and day. The old rubber hose is completely coming apart at the ends, it's swollen and bulging... just a mess. The blue hoses on the other hand, looks like it's brand new. For the record, I have many sets of blue hoses in my garage from various years, and they all look the same in terms of condition. Some are dirtier than others (I did clean this one), but none of them show any real wear at all.

You wouldn't have a '95-'97 lower and overflow hose would you? I can use pretty much any upper hose that I want since I no longer have the stock fan, but unless I want to go with a whale overflow tank (which I don't), I need a Aero specific lower. They are almost impossible to find up here as most Aero P71s have been crushed either due to rot or age/mileage. Would be cool to have a set of them.

I can't tell, but that doesn't look like a silicone hose friendly clamp. I don't see the inner shield (well, I sorta do, but it looks like you can see hose through the slots). Might want to do some pictures of the clamp if it is shielded for your write up. I have pictures of lots of cars with those, and normal clamps, and you can see how they dig into the hose and tear them up big time.

^ What he said. Need special clamps that are lined for the silicone hoses.

I have a couple of parts, but not sure what goes to what. The top hose I cut up (sorry) because I was planning on using it to bypass the oil cooler since I don't want that (it had a LONG straight length section of it). But there is currently one of those in the yard with everything else on it. If it's there next weekend, I'll pick up the hoses for you. I do know that the hoses are TOTALLY different than the other years. There is one long cooling hose (smaller diameter) that's super-long also.

So I heard you guys saying this last time, and I've run into at least a dozen Crown Vics now with the blue silicone hoses on them from aeros to 1st and 2nd gen whales, none of them had "shielded" clamps per-say. What they all do have though, which is different from other hose clamps that I've seen, is that the corrugated section of the hose clamp is never exposed to the actual hose itself. The hose clamp that's on there now wraps around the hose nearly the entire length so the "slotted" section, if you will... never touches the hose. Does that make sense? The band is also smoothed around so it doesn't have sharp edges (chamfered). But I don't see any "shield."

I am not sure, but I do not think that blue hose is OEM. I am thinking this because of the orange inside. On the SSP Mustangs the OEM blue hoses are blue inside and out. If you buy the aftermarket blue hoses they come with the orange inside. If that is the case with the CV's, then the blue hose may be aftermarket and not truly have 110k on them.

if there is a liner that protects the hose from the slots, so that you can't see the blue hose through the slanted slots used to tighten up the clamp, then they should be okay. Sometimes those the end digs in.

All "blue" silicone hoses from 95-02 that I've seen in the yard are blue inside and out. The hoses from 2003 to 2011 are blue on the outside with a brown layer on the inside.

They all have Ford part numbers on them too for what it's worth. I think they just designed them differently in 2003. Not sure what the brown inner core does that the blue outer core does not?

EDIT: I just looked it up because I wasn't sure why they were doing that. I found a bunch of performance sites that were selling aftermarket cooling hoses, and apparently the brown inner-core is a type of silicone that has a higher tinsel strength. All the quality performance silicone hoses have that brown inner core for added strength. I guess Ford decided to up the quality in 2003 over the previous years.

Ok, I'm assuming these clamps are the OEM ones since that's all I've seen, but yeah, the corrugated part is never exposed to the hose, which is nice. Definitely quality.

... also just wanted to add. I noticed that the temperature of the blue hoses when the car is fully warmed up is MUCH hotter than the black hoses that were on the car before.

When the car is fully warmed up, I can't even hold onto the upper hose because it's so hot, where as I could hold onto the rubber hose. I guess the blue hoses transfer heat much easier, even if they are thicker.

My temperature doesn't go up as it sits at sort of a 2/5th mark... just a shade higher than what would be the 1/4 mark. I have a stock thermostat, with a 50/50 mix of antifreeze and distilled water, and two bottles of Redline Water-Wetter.

Car has exactly ~50k miles on it now.

what is the stock thermostat 180 or 195?

Was just wondering as I see my 03 sits at 190F, so I would guess 195?

Try junkyards, not sure if Ford would even still have them.

Or a radiator shop could probably make some.
