You may have noticed the yellowing and cracking of your stock coolant reservoir.

If you have had problems with plastic radiator end tanks cracking from age, I'd take a moment to inspect your plastic coolant reservoir for the same reasons. The heat of the engine and the water itself ages the reservoir and makes it brittle and opaque (you may have noticed you can't really see thru it anymore anyway).

We have designed an all-aluminum replacement that matches our all-aluminum radiator for the 928. They are an exact drop-in replacement, requiring no changes to the car to install whatsoever.

They are priced only a little higher than the replacement OEM part, and it will be the last coolant reservoir you'll ever need for your 928.

I also have a "Racer's Model" available that does away with the coolant level sensor - photo below.

I have installed 2 of them so far and they work great. I will have 10 more of them here in about a week.

Our webpage about them is here:

Nice Carl!

I think that's sweet, although the only problem I would have is relying totally on the idiot light to tell me when I'm low on coolant. Did you consider connecting a glass tube on the bottom and running it up the outside so that one could quickly and instantly identify their coolant level? Other than that, I think this looks like a great product.

Hi Carl,

That is a nice idea! My only suggestion is maybe a "sight glass" in the middle of the side somehow for a quick visible level check.

I have seen a thread in sight glass that has a 2" diameter "window", might be an add on option?



Or a Vertical Sight Glass that attaches with NPT fittings at the top and bottom of the sight glass (cheaper).



EDIT, found a cooler one with a built in thermometer!!, Only $20 or so at McMaster...

Nice product, one that I need. And well priced.

Very cool Carl!!!

I agree on the site glass.

Oooh, good find Dave, that thing would be pretty slick. Verify your temp gauge AND check your coolant level, all in one go.

jleidel

neat... me thinks I need one for the new motor build.

One problem:

For outdoor applications, these indicators have a UV- and shatter-resistant nylon body and sight. They also have a built-in thermometer so you can check the level and temperature of your liquid with just one gauge. Thermometer is dual scale and reads 32° to 212° F/0° to 100° C. Thread into 1/2"-13 UNF holes or use the included nuts to mount to tanks with walls less than 3/4" thick (requires access to the inside of your tank). Temperature range is -65° to +212° F.

I guess it depends how high the "+" part is.

Most sight-glasses in auto service are classified as "additional failure points". I'd be more inclined to depend on the switch, and just pop the cap for routine level checks. My too sense.

Carl Fausett

Thats what I thought. We looked at it long and hard and could not come up with a glass window (which will quickly discolor) or a level meter that wouldn't reduce its reliability.

I went old school. You cannot see the oil level in the pan, either. You know what you have to do once in a while on a cold engine? Pull the dipstick and check it. Same here - take off the cap and look. Just like the power steering reservoir and the automatic trans dipstick. Part of once-a-month under-hood inspection.

The idiot light will still alert you should a problem arise mid-drive. I think thats important.

I check all the fluids every time I start the car!

Beer doesn't count.


Nice unit Carl. Just replaced mine last year (or was it two years ago...). Wish you had done this back then.

FUSE69

Sweet!!

Was thinking to get one of these custom made....

I'll be adding one of these to the list for my 'winter projects'

DR

OK then what about replacing one of the side panels with transparent alumnum?? That shouldn't cause an "additional failure point"

Sight glass or not, it is still a great idea and product, Kudos again to you Carl!
