Author Topic: Honda CR-V - AC Problem (Read 1365 times)

No H2O · « **on:** July 11, 2005, 10:27:02 am »

Vehicle: 1999 Honda CR-V, 108,000 kilometers.

October of 2003 I noticed my AC wouldn't switch on.

Summer of 2004, I filled the AC with a can and a half of R134a. The AC worked well all summer.

October/Novemeber 2004...same problem.

This seems to be a temperature related problem. It gets cold (near 0C) and the charge leaks out. I'm thinking of replacing all the O-rings/seals.

I could wait till October/November till it gets cold to install a can of R134a with a dye to find the leak.

What are the chances of it being a compressor seal leak?

Any comments welcome?

It could be leaking anywhere. Try a stop leak product good for Honda systems.

I suspect the O-rings (it only leaks when near or below freezing temperatures). The dealer gave me a schematic and part number print-out yesterday. I'll make a list.

I'm not one to use roadside fixes such as "stop leak" products. I'd sooner just fix it right the first time.

I've had excellent experiences with stop leak products particularily one called "Irontite" which is used for head gakets. It has saved 2 vehicles from going to the bone yard before their time. One a 6.2 GM diesel that I got 7 more years out of and my current off road Cherokee that is still running.

Some of the stop leak products and others have a red dye in them which is handy in spotting where the leaks are as it shows up. This is very helpful in finding the O rings that are actually leaking. I don't believe that the Irontite Steve is talking about is meant for the air conditioning but a good product for other purposes. It does work very well if used correctly I hear. Steve has used it and says its a good product so I do believe that it is.

"Steve has used it and says its a good product so I do believe that it is."

Huh?

The irontite product he was referring to I have heard of from other folks as well as Steve but have not used it myself as yet. I believe it to be a good product for its intended purpose.

Nice of you to say Barrie

Ya, I was talking about head gasket breaches. Irontite is amazing. I got turned on to the product from a diesel rebuilder who saved me a lot of grief. Anybody with a head gasket leak should try this product first. It lasts for the life of the motor. Probably best to flush the rad right after and pinch off the heater core just before useage. Car Quest stocks it.

Speaking of Carquest I was in there yesterday and picked up a Gal jug of Mcguiers Final Finish show wax for a little over $51.00. They stock the larger sizes of these products and you can save quite a bit on your detailing wax's this way. I think this is the best detailer polish in the marketplace. A lot of new car dealers use it on their showroom cars to keep them clean and shiny. It lifts the bugs off the front of your hood very quick with a soft towel.

A couple of tidbits, here in NB it's illegal for anyone to touch an A/C system unless licensed by the province{law dates back from the time of R-12}. That having been said my A/C tech in the shop swears by a product called Total, it's a sealer conditioner. Considering the low number of next returns he gets I'd have to say the stuff is worth the $20 that we're charged for it.

Just about everything is illegal in Canada, so I get my cans of R134a in the US. Under US$5 a can.

The minute something is illegal, dealers have a way of capitalizing on it...."ohhhh, we have to find that leak and it'll cost you a bundle". Well then, fix it once and fix it right!

I will keep that product in mind for my Bimmer. Ten years now and stored 6 months so I'm bound for a leak.

Same here in Ontario. Big form to fill out, supposed to find leak first and the repair and the fill.

No Thank You!

My sister brings it up from USA. Sold in Walmart.
Mexico still has R12 legal so American's do the same thing that we do for 134. So much for free trade/enviromental laws.

So we can blame this heat wave in Ontario on those who illegally refill leaking AC systems...

Thanks.

...on those who illegally refill leaking AC systems...

Funny you mention that. I have a neighbour who is going into New York State with his family today...going to some amusement park. He is taking his old Aerostar which has a slow leak...lasts the seaon with a fill of refrigerant. Anyways he is planning to buy the the container of refrigerant from Walmart and top up his van down there so as to have a cool ride home.
