Question 1

How exactly does it stop leaks? What supports their claim to stop leaks?

Accepted Answer

This stop leak product does NOT work by "scabbing" when it's exposed to air. You don't really want to use those types of stop leak products, because half the time they "scab" inside the A/C system and gum it up. This product contains methylene chloride. In large quantities this chemical is used as a paint stripper. In small quantities it softens leaky, hardened O-rings, causing them to "flow" a bit and seal if they're leaking.

Question 2

I thought this item was advertized  with a dispensor and guage, It is of no use to me without the dispenser and guage.

Accepted Answer

Interdynamics ***(ACP-105 PRO)*** doesn't have a dispenser and gauge, get the Interdynamics ***(ACP-100 PRO)*** and use the ACP-105 fisrt to seal and you will use it all and it will be  not enough to fill, then you have the ACP-100 to top it of...

Question 3

I have a 2005 honda pilot and never ever recharged my a/c.  Does Freon get used up after 11 yrs or could there be a leak?

Accepted Answer

No Freon means a leak at some place in system. Best practice is to get an AC service each year, modern machines vacuum out system and check it for leaks, then replace old Freon and with some new Freon tell you how low system was. Regular service also helps the system last/work better and longer. At some point most all systems will have one or more items fail. On an 05 Toyota Sienna when the front evap coil fails its a big job as you must buy the entire evap case, R & R entire dash to replace old case. online the part alone was $1100 best price I could find. Now ad labor. Fortunately for me a trusted shop I use did not try and gouge me like the quote from the stealorship.

Question 4

Is the refrigerant in this the 134a type?  Or does it matter?
