Decision on Coolant tank.

23 July 2003
Seattle, WA.
Hi all, I found that my coolant was low couple weeks ago, (didn't drive it afterwards), last night I fill it up to the max mark, and after 15 minutes driving, coolant was dripping to the floor. couldn't find the cause, but as soon as I release the cap(pressure within the tank), it stopped. Then I saw a little crack that's around 1/2 inch. Wondering what would you guys recommend for the replacement? I couldn't decide but I'm leaning towards the following 3 choices respectively:

1. SOS: like: the oem styling after installed. Internal Baffle. Cons: the most expensive of all three.

2.OEM: like: Mine lasted 14 yrs, I should be able to get one for less than $100. dislike: Since I will track it in next 7 months and planning going to nsxpo, should I take the chance??

3. Dali: like: The quality and workmanship. lower price than SOS one. dislike: Do not like the "Milk bottle" look after install, lack of baffle.

Could anyone help me?? thanks in advance.

I love the SOS. It looks the best of all to me and is worth the extra money.
It is a good choice if you ever want your engine bay exposed.

I also am happy with the SOS tank. I had the Dali and switched to the SOS since it was designed more to the stock tank with the internal baffle.

OK, it is SOS for me. I like the fact it retains the factory mounts, retains the factory shape and baffle. It looks like a quality part and will definitely solve the problem of a possible leaking or cracking factory part.

The only question is red, black or polished. The price seems reasonable for the obvious quality of the part too. Just my 2 cents.
Thank you very much on everyone's comment. I placed the order for a SOS one too.

I do strongly recommend SOS considering nsx3.0's custom color... or maybe even the titanium color like the 91 nsx cluster.
I've got an SOS tank and very happy with it.

Please post pics once you get it. COngrats!!!
Thanks Doc C, but my engine compartment is bone stock and not as clean as the others, I only ordered the Silver one, so it'll be pretty under-stated, I think.

I'll try to take some picture when I got it done. :smile:
I've seen Nate's Coolant Tank and it's a grat addition to the engine bay. The chrome looks like it should have been there from the start. A mod I will soon capture.
