Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Issue is the system only took in 5 gallons to fill when the Bentley manual says it should be just under 5.8.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

So I changed the coolant in my ‘04 S because it was green. As I am not sure what was in there (was done before I bought it). I flushed the system twice with a hose, drained it by removing the drain plug on the 3rd rad and “lifting” the hoses on the main rads with a small screwdriver (difficult to remove those hoses) and finally blow the lines out with an air hose. Refilled today with Porsche coolant using an airlift. Issue is the system only took in 5 gallons to fill when the Bentley manual says it should be just under 5.8. Heater was on on drain and filling. I also did the WP and low temp thermostat while in there. So advice: should I drain and refill (adding another gal of P coolant)? Start over fresh with new P coolant and distilled or just call it good and drive it? FYI Chicago weather but car is garaged Nov to May. Thanks all Mark

Did you open the vent valve at the reservoir and run engine for a while to get trapped air out? I don’t see a need to drain new coolant only to refill.

This is a source reference. Confirm exact model applicability in the original material.
