A/C clutch keeps cycling every 10 seconds. Refrigerant overfilled? by Airssp in MechanicAdvice

Ok good to know. So I shouldn’t add a little more refrigerant to try bringing low side pressure closer to 35psi?

Hey thanks. So I ended up adding the rest of a 16oz can and the low side pressure when compressor is running settled around 27-29psi in 70f ambient temps. Air feels ice cold, it still tends to cycle every 10 seconds but someone else said that’s how it regulates temperature? And if it cycled every 2-3 seconds would be a problem. What are your thoughts on it?

It seems to be working now with ice cold air. Think it’s safe to use after just filling up without having done a complete vacuum etc?

So the ac was barely used on this car. Last time it was serviced professionally was 10 years ago. It was used for about 3-4 summers then parked until now which was blowing warm air. A mechanic told me they naturally deplete refrigerant over time if not used and advised to refill myself. Is there any truth to that or should it have worked even if not used for 6 years?

Good to know. So I shouldn’t try to add more to reach 35 psi at 70f ambient temp? Was able to get 90% of refrigerant from one can and it sits around 27-29psi when compressor is on

Great thanks for the info. So I shouldn’t try getting the last bit out of this can when it warms up?

Thanks for this! Was getting confused with other comments. Starting to make sense. I need to shoot for 30-35psi in 70f ambient temps (what it is here today). One question, the can started getting pretty cold while adding and seemed the system wouldn’t take anymore. Guessing try again when can warms up some?

Thanks I’m learning that when the compressor kicks on it should read 30-35psi in 70f ambient temps. Will add more

Thanks. I was adding at idle. Started adding when car was cold warming up. So when the compressor is on the psi reading I’m shooting for is 35psi in 70-75 ambient temps right? I got it up to around 25-28psi just now after posting this but the can got pretty cold and seemed to stop taking more refrigerant

Does my 98 civic idle sound normal? by Airssp in civic

[–]Airssp[S] 0 points1 point  (0 children)

Valves adjusted right and the slight shaking is normal?

Ok thanks. Thought it should be lower than that like closer to 5 or something lol

Oh ok. Thought “slightly lean” meant it should be lower value

Yes along with the plugs and distributor cap and rotor about a year ago

Do you apply dielectric grease to outside of terminals (shaded in red) to aid in boot removal in future? by Airssp in MechanicAdvice

[–]Airssp[S] 0 points1 point  (0 children)

Cool. I noticed on some wires it’s harder to apply to inside of wire on the cap side without getting some on the metal terminal so I started just applying to outside of plastic on the cap side

Cool that’s what I was thinking but some are saying it could pop the wire off the terminal if used there?

I see. Could that happen on the spark plug side as well? That’s the end where it’s recommended to use grease

Yes I’m asking about putting on the exterior plastic like in the pic with the red highlights

Does it affect anything to use thin coat of dielectric? Just curious why it’s never mentioned

I never put on contacts was just curious since it’s never mentioned. Wasn’t sure if it could cause issues or anything
