Product Description

Air Conditioner (A/C) Conversion Kit, R-12 - R-134
This A/C Conversion kit will completely and correctly upgrade your fox body 1984-85-86 Mustang SVO R-12 system to the newer R-134A system. It includes a new Mustang compressor, lines, condenser, all hardware and instructions to upgrade, as well as a stock length V-belt. Converts stock Mustang A/C Components to aftermarket, which means a more efficient compressor, bracketry, and new refrigerant hoses for use with the less expensive R-134A refrigerant.

Problems with Mustang A/C systems can come from various sources-leaks, parts failure, electrical gremlins, and thermal issues. Any one of these - and quite often a combination of - can cause the A/C system to blow warm air. Typically, the fix is to replace the offending part or reseal the leak and then recharge the system. Unfortunately, with R-12 refrigerant prices being what they are, even a simple $20 O-ring repair will require several hours labor and more than $200 in R-12.

Fitment Note
-Will only work on Mustangs equipped with A/C from the factory. Dealer installed A/C or non-A/C equipped Mustangs will not work.
-1986 SVO owners have a 3 groove water pump pulley. This pulley will not allow the belt to grip the A/C pulley properly. 86 owners will need to source a water pump pulley from an 84-85.5 SVO for proper belt function.

Many people sought to convert their Mustang R-12 systems to R134a simply because the latter is cheaper, readily available, and can be bought without a license. Unfortunately, when R134a is introduced into a stock R-12 system with nothing more than a few new seals and some oil (the popular R134a conversion kits you see at the parts store), the A/C system isn't as efficient and vent-outlet temperatures rise. The best way to repair your A/C system and properly convert to R134a is to replace the components that hinder the R134a conversion, namely the condenser and the compressor.

Hose Wizard's R134a conversion kit for SVO Mustangs is the perfect choice for this repair. The easy-to-install kit includes a high-flow R134a condenser, a Sanden rotary compressor, hoses, mounting brackets, and R134a pressure switches.

The components of this A/C Conversion kit are designed to work as a kit and are not available separately. OEM Ford parts WILL NOT interchange with these 134a conversion kits!

4 Stars   All parts and hoses lined up and fit perfect

Image uploaded by Kelly C. Easy to install. Parts fit correct, hoses actually laid right against the factory straps. Only problem, minor one, was the belt shipped with the kit was way too small. Had to pick up a generic belt at the local parts place.

Yes, I would recommend this item to a friend!

5 Stars   Great Kit! For use with SVO's that have the lower 3 groove pulley
By on 11/25/2016
Image uploaded by Richard H. I am very pleased with this kit and Hose Wizards that makes it. However, this kit will ONLY work with SVO mustangs with the LOWER 3 GROOVE PULLEY! If you have an SVO with the 3 groove water pump pulley like an 86 model. The belt WILL NOT grip the new compressor and will squeal when the compressor engauges. I was lucky and had a LOWER 3 GROOVE CRANK PULLEY. it's an easy swap and I reccomend changing the water pump pulley to a 2 groove. Other positives are the kit comes with all the brackets and bolts need to install. It made life easy to set up. Other things to be aware of. Your SVO cooling system must be stock or spec'ed as stock. NO OVER SIZED RADIATORS and fans much turn on via the stock setup or the system will fail and no warranty. The phone support was awesome and VERY help during my setup. They do reccomend professional setup if you are not skilled in AC install. I hope you find this useful.
