Employing a blunt-edge putty knife, press the sides in the console outwards, to make sure that a person facet from the storage tray might be pulled out. Then, the opposite aspect will occur absolutely free effortlessly. This is less complicated than endeavoring to pull the storage tray straight out.
[Editor] Your evaporator is way easier to eliminate than that inside of a 740 or 940. Eliminate the battery adverse and evacuate the air conditioning method. Get rid of the firewall connections, such as the metallic plate and washer, for the pipes resulting in the evaporator. Clear away the glove box and passenger kickpanel, then the plastic evaporator include. Pull the evaporator out. You could have to eliminate the air bag bolster (the massive steel bar near the glove box) whether it is in the way in which with the evaporator. Hose Substitute. [Suggestion from Rafael Riverol] After i retrofitted my 760T A/C from R12 to R134, I set in all new Volvo parts from Swedish Engineering which includes new hoses. Before long, I found all the hose from the compressor to condenser glowing inexperienced with UV dye for the reason that R134 was leaking correct through the body on the hose. Later on, I found out that Volvo has info out recommending use of barrier type hoses when retrofitting A/C to R134. It turns out, unique hoses will maintain R134 only when saturated with mineral oil applied with R12. New hoses or flushed out previous hoses (cleaned of mineral oil) will not likely hold R134 for the reason that its molecules are smaller sized than These of R12. I had gained and set in the vehicle an original Volvo hose very good just for R12.
[Responses: Dave Stevens/Norm] The only almost certainly offender for your soaked carpets can be a plugged evaporator drain - look about the firewall, passenger side - you ought to see the drain outlet there - could possibly be flush With all the firewall, or there might be a tube connected that operates down towards the body rail. The plastic casting for the lower air-box half actually consists of the drain spigot.
Warm air is leaking in. Test the seal all around your window device to ensure incredibly hot air isn’t acquiring in (or cold air is just not seeping out). If that is so, reseal all over your device with weatherstripping.
Make sure to set in new barrier type hoses built to maintain R134 when retrofiting from R12. Rebuilding Hoses. I've discovered that adaptable ac lines ordinarily commence leaking at around 100k miles and can be expensive to exchange. I have Situated a maintenance service in Tucson that can repair your present line for approximately $50: mail them the previous hose and so they rebuild it . They appear to try and do excellent do the job. Century Auto Air. [Jim McDonald] Hydraulic hose outlets with Parker functionality should be able to rebuild the hoses and fittings. Anecdotes on Brickboard note that Volvo OEM availability of such elements for 740/940 vehicles is diminishing so we could possibly be accomplishing a lot far more rebuilding of unsuccessful hoses and areas. Lousy Good quality Handle in New Hoses. [John Orrell] I obtained an excellent looking Volvo sourced AC hose from FCP Groton this week. It was in a very sealed bag, Volvo labels all over it, built in Poland. It even experienced gentle rubber addresses around both equally ends with the hose fittings. But After i taken out the rubber addresses, I saw a fairly big quantity of metal shavings inside the hose/pipe finishes from wherever they Reduce the ends to sizing. There were more than enough shavings that it might have carried out damage to the compressor, so When you are changing a hose, inspect for shavings and flush as necessary.
Receiver-Dryer Replacement. [Editor] When replacing the receiver dryer canister, measure the refrigerant oil contained inside the previous device and fill The brand new just one with contemporary oil of a similar quality and amount.
Check for a blower motor issue. The easiest way To achieve this is to try turning in your heat. For those who have weak air stream in the event the heat is on at the same time, your blower motor can have absent out.
[Notes from Adam/Randy:] It is tough to get the reduced housing again in position [see Strategies underneath]. The situation is that the again of that reduce deal with (nearest the firewall) needs to slip around the evap, that has a pipe loop hanging at the lowest stage. That pipe loop hangs right wherever the firewall can take a bend in direction of the cabin, as well as the proximity of that pipe and also the incline on the firewall makes it nearly difficult to sneak the quilt involving there without having breaking the plastic. Something that assists is to achieve again with 1 hand and push the evaporator from the firewall a bit, Because the housing catches about the tube on the bottom of the evaporator. I also cut the drain foam plug in two on The underside and resealed it with RTV, which gives you somewhat more home. See the guidelines underneath. Reinstall evaporator cover screws. The screws are very easy to strip from an excessive amount of torque. It is best to look at the box Whilst you're turning the screw. Quit turning when the cover contacts the box (rather than turning until finally the screw feels restricted.)
No. Increase fifty get more info percent of the can of r-134a as in depth during the manner explained from the future ways. If the compressor continue to fails to engage, take your car or truck into a mechanic.
Put on basic safety Eyeglasses and operate within an open up natural environment, where by fumes received’t overwhelm you. By no means touch your eyes or mouth after managing Freon or other substances. Put on extended sleeves and gloves Anytime feasible.[9]
in the compressor or, based on the product, at the receiver dryer. If for any explanation you may have not sufficiently flushed the method of debris, the display screen will catch it in advance of it destroys the compressor, sending new particles out the two the superior and reduced tension lines. Airsept has illustrated instructions at its Web-site: see the photo to the appropriate. This machine will never slot in numerous Volvo compressors; if not, put in a different filter during the liquid line within the passenger's aspect in the condenser. Be aware that insufficient flushing (and ensuing inadequate lubrication) is the greatest cause of the failure of recent compressors: begin to see the notes beneath. Verify and exchange the orifice valve while in the large force line connection within the passenger side, not for the evaporator link. Maybe a variable orifice valve known as for, but I get 32-34 degrees Farenheit air in the vents with the manufacturing facility orifice valve. Change the accumulator if it has been there for a number of years or a lot of miles or traces were still left open up a lot more than ten minutes so air obtained in. In any other case, Volvo says it could be improved each individual 2nd or 3rd time you open up the A/C traces. Set in at each connection you open fresh R134 O rings (yellow, not black) lubricated with both mineral oil or an software-unique, silicone-centered lubricant as an alternative to PAG or POE oils. (PAG or POE oils shouldn't be utilised due to their hygroscopic character that may boost dampness attraction, potentially resulting in o-ring deterioration or thread fitting seizure.) Draw a vacuum of 29.seven+ inches of mercury for a minimum of one hour. Check out the procedure maintains that vacuum When you turn off the vacuum pump. If you use Johnsen's R134 refrigerant in liquid variety (you turn the can the other way up as opposed to maintain it upright like with Dupont Sava R134) preferably with UV dye, the vacuum during the system sucks in a can or two at once.
[Response: Chris Herbst] The clutch biking orifice tube (CCOT) A/C devices such as the 1 inside your Volvo are designed to cycle the compressor on and off to keep up a workable process tension. Though the thermal enlargement valve units in other cars change other aspects, the FOT (preset orifice tube) ought to possess the stream taken care of at a steady tension.
In the event the needle over the dispenser reads under the minimum acceptable tension, commence filling the process.
No significant offer. Then mount The brand new motor, solder the wires, and close every little thing up. 760 with ECC; 960; S/V90 Blower Motor Substitution. Clear away the battery floor lead, the passenger kick panel, the glove box, the kick panel in front of the doorway, the a/c ductwork, the bracing/crashbar (still left bolts get rid of simplest more info from radio compartment)and the best crashbar mount. Clear away the terminal strip and bracket holding the again on the motor, then the electrical connector as well as the motor alone. When reinstalling, remember the rubber gasket throughout the housing. The vent process within the 960 can suck paper and debris really very easily when in recirculation mode. It usually ends up inside the blower motor assembly, Positioned underneath or powering the glove box. Get accustomed to eliminating the blower motor to retrieve the debris from The within from the squirrel cage. You'll probably be surprised at what else you discover in there.
