Sorry to hear that Nippon Denso has got you feeling that way.
Honda has the "use Honda brake fluid, Honda coolant, etc." even though Honda doesn't actually manufacture any fluids.
And then there is Nippon Denso Oil 8 -- which is PAG 46, and you can take your pick of manufacturers/distributors of PAG 46.
As per your original question, the only source for ND Oil 8 will be a Honda dealership (or Toyota dealership, etc.). They'll likely charge you quite a bit more than an arm and a leg ... but some of that cost will be for the parts guy to remove the dust from the bottle before he presents it to you.
Thanks. I found it local. It was easy once I knew what I was looking for.
Another question, I have found the condenser for a wide variety of prices. I am assuming the more expensive ones come with all the brackets and what-not and the cheaper ones come with the condenser and drier only. My question is, do i need to replace all the brackets and such or could I just not replace the condenser/drier and put new o-rings in and then get it vac/charged up? What do you think?
Personally I wouldn't worry all that much about the hardware (brackets and rubber mounts) - those are likely fine. Nice to have new ones, but likely not essential. However, if I got in there and found that the mounts were deformed/damaged or whatnot I might wish I had new parts.
I would worry more about the quality of the condenser itself AND the desiccant/filter. And for some of those online prices you might search up you need to be careful to note whether or not the filter is included or is a separate item. The drier "housing" is permanently attached to the condenser, but the filter/desiccant can be a separate issue/cost. You do want to use a new (high quality) filter. Also note that, at least sometimes, "perfect fit" after-market parts are anything but...
Personally I would go with the Honda OE part which comes with the desiccant/filter - when I looked online to respond to your other post/question it seemed to be about $270 (for a 2001). That's not horrible. And, if I interpreted the schematic correctly, it came with all that nifty new hardware.
But, it does depend upon the price differential (and how long you hope to own the van) as concerns using after-market parts. And, of course, it depends upon the reputation of those parts.
Sorry I can't really give you an answer. And sorry for the rambling attempt...
Thanks for your thoughts. I like the idea of cheaper cost but I have found I get a much better return on my investment when I use OEM parts. They fit better and typically work and last longer. Thanks again for your insight in this matter.
