their respective sprung positions. 960/ninety With ECC: Recommendations. [Idea from Steve Lengthy for 960 ECC] When you've got completed the tests over and you are still acquiring a challenge while in recirculation method, seek to pinpoint the lead to to a specific vacuum motor. While using the recirculation on as well as controls established to max supporter velocity and sprint vents, accelerate right up until the air no longer flows within the vents and then set your hand down beneath the sprint to determine if air is flowing from the floor vent. If Here is the case, then the recirculation vacuum motor is probably going leaking. [Idea] In a 960, it is possible to pop from the panels on possibly side and put a clamp around the recirculating bellows (orange hose)and push the car and find out if the situation is long gone or put a clamp on the floor side from the bellows (Yellow hose IIRC), or both (as inside our circumstance), and find out if it goes absent. If it does, the respective solenoid is at fault. The vacuum reservoir Found guiding the glovebox may well also have a leak (common difficulty on this design). Sad to say, of their infinite wisdom, Volvo opted for making the canister Element of the evaporator case (Really high priced). I replaced mine using a independent and independent canister. Any good A/C shop can try this. You may as well just completely cap off the offending vacuum line (likely orange or yellow), Despite the fact that you may shed some performance. Eliminate the glovebox to locate the vacuum junction box With all the traces put in. All: Changing the Vacuum Motors.
[Editor] Your evaporator is way less difficult to remove than that in the 740 or 940. Eliminate the battery unfavorable and evacuate the air conditioning program. Take away the firewall connections, including the metal plate and washer, to the pipes bringing about the evaporator. Take away the glove box and passenger kickpanel, then the plastic evaporator address. Pull the evaporator out. You will have to get rid of the air bag bolster (the large metallic bar near the glove box) if it is in the way from the evaporator. Hose Alternative. [Suggestion from Rafael Riverol] After i retrofitted my 760T A/C from R12 to R134, I put in all new Volvo components from Swedish Engineering which includes new hoses. Soon, I discovered your entire hose from the compressor to condenser glowing eco-friendly with UV dye due to the fact R134 was leaking correct throughout the human body of the hose. Later, I found out that Volvo has information out recommending usage of barrier type hoses when retrofitting A/C to R134. It seems, first hoses will maintain R134 only when saturated with mineral oil used with R12. New hoses or flushed out outdated hoses (cleaned of mineral oil) will not likely maintain R134 for the reason that its molecules are smaller sized than These of R12. I'd received and put in the car an first Volvo hose very good only for R12.
Richards techs smeared their fingers next to the thermostat. That is how they left my basement when they set up the new wire.
Anyway I called the owner and he said "simply because I'd a concluded basement it had been more durable to offer pricing prior to hand", but I haven't got a completed basement!!! So he advised me "doesnt subject, acquire it or leave it". In my problem I had to tell them to go forward.
I contracted them to accomplish the yearly service. They found my AC was busted so I required replacing. They certain me I'd get a estimate Soon via e-mail.
I suppose they're going to find a method of getting that additional $forty. I have asked for a brand new, properly itemized Monthly bill for my documents due to the fact the initial mirrored $one hundred seventy Service Cost.
Check out continuity of your respective small tension switch: I Car Air Conditioning had a nasty minimal force switch. I bought TWO undesirable switches from Volvo, in advance of I bought a third aftermarket switch from a place called The Volvo Website, element number 1343216. I forget about the precise force rankings, Nonetheless they swap off (open) close to 20psi and again on (near) about 40 psi. The terrible types I obtained would change open at close to twenty psi then presently close again. This prompted the compressor to cycle faster that you can rely. Trying to determine it out drove me nuts. [Editor] The location from the change ("2" in the Picture previously mentioned) within the receiver-dryer ("one") causes it to be subject to damage when changing distributor caps, and many others. Unexplained compressor cycling when you know the method is billed really should lead you to definitely suspect a faulty minimal stress switch. Air Conditioning Leaks.
Supplied 12V to your contacts with the reduced strain switch, (compressor did interact), billed the A/C to thirty PSI within the small side, installed the switch back, but all over again similar matter as higher than.
Resulting from the number of responses I thought it greatest to add an additional website page to address a number of them and to answer many of the questions and clarify some matters.
[Responses] Issues are prone to be present in the vacuum program that controls the opening and shutting of the flaps from the AC vent ducts; particularly, the vacuum Regulate Check out valves, diaphragms and/or defrost/ground vacuum motor, Situated just higher than the accelerator pedal, or inside the integral vacuum reservoir built-in to the evaporator scenario.
Lessening the stream level of chilled drinking water is like decreasing the cooling capacity of your process. This could trigger big temperature distinction between provide line and return line of chilled water meaning "awesome" is not really ample to get rid of the warmth.
Not surprisingly, movement rate is An important variable And that i wanna few this with drip irrigation and a considerable Backyard :) This really is an awesome plan! I had considered it, but had not set it to work. A lot praise 'ol mighty inventor, people today for example by yourself are the last line of protection in Power corruption.
[Response: RL] There are actually many sources of possible vacuum leak (like a lot of the vacuum motors (bellows) on the particular heat AC procedure) but People two valves are a typical dilemma. They can be Test valves to forestall lack of website vacuum and if you bench-check them separately, it's possible you'll discover they perform effectively below a fair volume of vacuum but that as soon as you are attempting nominal vacuum, the valves will surrender. You could try out cleansing them out in WD40 or some rubber-softening material but failing that, your very best guess is probably an OEM replacement. [Dave Stevens] For those who have a turbo, that hiss is from the pneumatic vacuum reservoir for the dash heater & A/C air distribution system. Your turbo takes advantage of a vacuum pump rather then manifold vacuum to evacuate this container which is why your indicators are visible under acceleration as opposed to deceleration as you'd anticipate with the NA engine.
The moment you start the engine, suction in the compressor will suck a 3rd can. That is certainly 36 ounces in lieu of the 32 ounces named to the A/C around the 960. That works for me, but I try to remember Tom Irwin recommends a small food items scale to put in precisely 32 ounces of R134. If You will need to alter the condenser, I discovered the click here direct suit aftermarket just one from FCPGroton has the gain more than the condenser which was in the vehicle (Volvo?) of no steel plates in opposition to the aluminum. Usually, that aftermarket condenser is a little shorter top rated to base compared to one which was in the car, with spherical rather then flat tubing. I are unable to compare ability (BTU) in between the two condensers, but to this point that aftermarket unit gives me 32-34 levels Farenheit air within the vents while in the tropics! Valuable Air Conditioning Elements, Goods and Instruments. AScanTech (Avantia) immediate healthy aftermarket condenser is $175 from fcpgroton along with a Volvo a single is $439 from Swedish Engineering. A fresh (not remanufactured) Sanden SD7H15 compressor is $320 from FCPGroton. Locally, I used to be quoted $995 (Certainly, $995) sight unseen so I have no idea whether or not it absolutely was new or remanufactured. An accumulator will cost you $fifty from FCPGroton and maybe a couple of bucks far more from Swedish Engineering. A Mastercool flush gun is $43 and flushing solvent is $20 a bottle from You may need shop air to employ People. The Airsept package with "Compressor Guard" screens to maintain debris within the procedure from getting into your new compressor costs $67 from . For leak detection, get an Airmax LED penlight for UV leak detection from (costs about $40) and a set of UV-boosting glasses from JC Whitney for approximately $five. You can purchase air conditioning dye injectors from NAPA. The glasses are required to see the dye. To seal pipe joints with o-rings, get some Nylog, which is appropriate With all the o-ring material and stops corrosion.
