Aircon seals generally don`t have anything on them but a little silicon grease or silicon lubricant if you have some is a great help. Don`t use anything else as it will ruin the seal.
It`s worth having a go at taking off the front bumper. The first time is a learning curve and will seem worse than it really is. There are two types of Drier ( early and late versions) so be sure to get the right one. |

First of all, if the system has been leaking, you will need to have it vacuumed down and leak tested prior to refilling the system with gas. From you comment about being new to air con i suspect that firstly this will be news to you and secondly you won't have the equipment to do it or know how to use said equipment.
With this in mind, i would suggest the following : Do what you can in terms of fitting new parts but don't fit the new dryer yet. Find a good air con specialist (not the likes of Fik Wit and similar "high street" places") that knows what they're actually doing, phone up and explain you've had a leak, the system emptied itself and you've replaced the leaky pipe so you need it vacuumed down, leak tested and then regassed with new oil and leak dye. That way the specialist can advise you of the costs of the individual parts of the procedure and the total cost of the new oil (it's mainly the compressor that needs the oil, you don't want that contaminating the silica crystals in the dryer! ), leak detector dye and importantly, the gas. As i'm sure you'll agree, there's no point regassing it if you haven't got it leak-free, only way to be sure is to vac it down and leak test it. If all is well then, the dryer can be fitted (again, no point opening the new dryer until you know the system is leak-free), vac down again, add oil, leak-dye and gas and get it working again. One important safety tip - no smoking while working on the system! Some refrigerants can react with tobacco smoke to creat cyanide gas. It could be an old wives tale but i've never fancied putting it to the test! You may think the system is empty but it won't be truly empty until it is vacuumed down to nothing.

I asked if the two air con pipes can be accessed from the engine bay ,you appeared to say yes !!!!!!! After a lot of hassle removing the engine bay scuttle cover wipers arms etc ,There is no access the the pipes ,only the wiper motor.So it appears the only access is from within the car ,which i was dreading as it looks a real hassle.

Hi.
You asked if the pipes are accessible from the engine bay and the answer is yes. They are removed by taking off the small cover ON THE BULKHEAD and not by removing the scuttle panel. Look to the right of the Brake Servo and you will see the two pipes passing through a plate secured by two nut-type fixings. Remove that plate and you will see the two pipes attached to the Expansion Valve. You will also need to raise up and move aside the Coolant and Steering Reservoirs to give access to the rest of the pipework. The only pipework the other side of the Expansion Valve is on the Evaporator itself and you won`t want to go there. |

Appologies,I was convinced the two air con pipes could only be accessed from inside the car .The two bolt threads sticking out in the engine bay threw me .I now see the two strange looking hollow nuts undo. One pi of a job to replace the bigger of the two pipes,without taking any other pipes apart,but im getting there.
