451 A/c Dead :(

14 posts in this topic

Today was warm enough to test the A/C properly, and indeed, it doesn't do squat.Is there an easy way to diagnose where the problem might be? It wasn't very strong last year, but, I have no experience with Smart's A/C and nothing to really compare to.Should I look for a local A/C specialist? Go to a dealer? (I hope the last is not an option... I am scared!)If you like to provide links to other pages please go ahead. Searches here and google didn't result in very helpful results for me.

Here is a useful link: http://clubsmartcar.com/index.php?showtopi...00&hl=freon

I recharge the air conditioning system myself every year or two depending on the severity of the winter. The o-rings shrink when cold (-20C or colder). This allows the refrigerant to leak out when you are least likely to need a/c.

A Duracool or similar refrigerant and recharge hose/gauge are very reasonably priced compared to the alternatives. There are instructions available somewhere here or on Evilution's site on how to do the recharge. It will work better than new. Fairly easy to do.

I can assist you with it Lito. A 6oz can of RedTek sells for less than $20 at CTC which should last you the whole summer(both weeks!)It probably will require removal of the front clip which is secured somewhat the same way as the 450

Guess it depends on which kit you get; eBay has some with longer hoses. :)

My ac was evacuated with the engine swap, just recharged it with the kit from Walmart. Blows at 43F now. Pretty simple job on the 450, haven't done one on a 451 yet just makes sure you tie into the low pressure side and run it with the ac on high. post-12052-1399835551_thumb.jpg

Wow! Lot's of great info. Thank you guys.Mario, I may get in touch with you about this, but you are a mechanic and I would not ask you for a freebie. Now... If a bottle of red wine or similar is accepted in trade... ;)

Can you come up to Kanata? I'll be gone this long weekend but I can do it 23-25 May. Just get a can of Redtek from Canadian tire or Duracool from Walmart

That sounds great Mario. I'll get in touch with you via email after this post, but, I just want to share that it would be a great opportunity to make it an instructional video to post here.

In the meantime... Which of these would you recommend I get?

Both are basically the same, I've used both products in the past. My old 300e had an impossible to find AC leak even when I had everything changed, the quick seal (duracool kit) stuff actually works and it expands the seals. If yours leaked it might be good idea to get a bundle that includes it IMO

Topped up Lito's a/c this morning. Like the 450, the gauge of the a/c fill kit interferes on the 451. To get around that, the front clip can be removed. I had to use a slightly longer hose so the clip need not be removed

My AC has croaked again this spring,so after a failed pair of repair attempts in two weeks at the local foreign car garage it looks like I'm dragging out the Duracool..... again.
