Jim, on mine the receiver/dryer looks pretty simple to change. It is right under the front hood on the passenger side up by the firewall. The shop estimated 1 hour for that part.
I am not sure exactly what is involved with flushing it out. My shop said about 3 hours.
The worst part was changing the expansion valve. This required removal of the entire dash and coming up from the passenger footwell. That is what is taking most of the time and cost.
Hopefully with receiver/dryer change out and flushing you won't have to do that.
I plan on changing the receiver/dryer again and flushing it out in about 5 years to be safe. |

OK, I think I better change mine, its 12 yrs and I believe in preventive maintenance. What's the procedure? |

This is exactly what happened to my 92 512TR. It is currently in the shop getting a new expansion valve, new receiver/dryer, flushing out the lines and replacing one of the lines due to contamination and corrosion.
I think the dryer was the original one and the car was first registered in June 1993, 10 years ago.
Thankfully, the dealer, Sean Harris of Steve Harris Imports is standing behind the car and taking care of the repair bill.
When it is all over I will post a summary of the ordeal and its happy ending. It's been in the shop now for over 2 weeks. |

No it would not normally necessarily be included.
As Tom mentions, when Dryers get old they puke the desicant, plugging the expansion valve, rendering the system inop. If you can afford "preventative maintinance" by all means replace the Dryer at least every 10 yrs if not sooner.

If you have a blockage, it is because the material in the dryer has come apart and clogged the expansion valve. It can be cleared by back flushing it with a A/C flush system but it is better to let a professional do it. This is much easier than trying to pull the expansion valve. I have done a few of them both ways and I will always try to backflush it first. Much cheaper if you are successful in clearing the desident out. |

does anyone know how to change it out? the owners manual recommends changing it every year or so. my AC doesnt work and my mechanic friend says its due to a blockage in the dryer.
is it accessed through the front bonnet area??? |
