I believe DougC switched coolant types (non-OAT, green/yellow). I thought there were pictures somewhere, but I can't find them. If I recall correctly, it remained clean for the several months at which point he ended up selling his car anyway. There was also someone who bought a salvaged/repaired vehicle that used it. I don't think there will be issues (if well-flushed), OAT is just supposed to last longer.
I wish that I got rid of this piece of garbage, sadly I still own it. Happily there is light at the end of the tunnel as I am currently searching for just the right deal on an Accord Sport 6spd and will hopefully be rid of my Focus soon. Radator number THREE goes in it this coming Tuesday. Number two failed at the seams just like the original one did. Not even 52,000 miles on this thing yet....

WD-40 causes rubber to swell slightly, improving the seal. The company claims it is safe on rubber but I have not seen any long term test data.

jcw122 Another owner here with low coolant level at 24k. My cap has a a bit of clear-ish orange fluid on it but not very much at all. The design of my cap also appears to be different than the OP's.

I just don't want that hose clamp to upset them if I ever have to make a warranty claim.

Thoughts? I'm 90% sure if I take it to these guys they'll return it to me cleaned up and say they couldn't find the leak.
Hi TurbineWagon,

When you have a date in mind for the appointment, please send me a PM with your VIN, updated mileage, best daytime phone number, full name, and dealer name/location.

TurbineWagon I scheduled an appointment for Wednesday, we'll see how it goes.

sailor Take it to them & point out what you found.

Let them investigate & repair.

Yes, just putting a hose camp on & calling it done seems like the easy fix. Devil's advocate says - "what if it got tweaked at some point & the outlet to that bottle is cracked? Take it to them untouched & you get it taken care of free.

That exact thing happened to me with a washer bottle many years ago, it was much nicer not to pay for the replacement.
