I have a 2005 Crossfie, basically a MB320. AC gauges show high pressure on high side and low pressure on low side. So I’m thinking the expansion valve is likely the issue. I have a new one to install. I also got a new dryer. The dryer is a bit of work to install. Would u run the old one or install the new?

 

So is PAG 46 a good option for ND-8 refrigerant oil? The ND-8 is hard to find and very expensive. I only need<3 oz according to the service manual for replacing the receiver/dryer.
thx

 

Will definitely be replacing the dryer.

 

Crossfire A/C refrigerent types

I saw the above article. I hope it helps.
You have to scroll down to the Crossfire section.

 

HUH?

You did not tell us what the symptoms are nor what you have done up to this point.

 

No cooling. High side is too high. Low side is too low. FSM points to possible expansion valve is plugged up.

 

Question is : can I add PAG 46 to the system or do I have to find ND-8? Seeing conflicting answers to this on the all knowing internet.
Thanks

 

Ordered some ND-8 on line. $30+$15 shipping can’t seem to get a straight answer if PAG 46 is compatible. Little more$$ and time, But some pice of mind.

 

I posted this before. If you click the link and scroll to the Crossfire section, it looks like PAG 46 is compatible. I don't know **** about refrigerants, so you should verify this yourself.

Too many conflicting publications. I don’t know. Already spent the $ for the ND-8. Hopefully this thread can confuse others in the future too. Thanks guys!

I've been confused from the first post (#1). Wish you luck with your repair.
