You need to use 5 to 6 gallons if ALL of the coolant was previously evacuated properly.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

So I had an accident and radiator got damaged so the coolant spilled out. The car was in the body shop for 4 months, they don't know how to properly top up the coolant system so I offered to help, I read though the forum here and there are great instructions on how to do it without the vacuum tool. Anyway, we got the rear end slightly in air, cabin heater to max, opened the bleeder valve, topped up the tank, turned it on, slight revs, topped the tank again and so on. We put about 3 gallons (12 liters) of coolant in. Temperature was rising steadily and normally, as it got to about middle in the gauge (that's the operating temp) coolant started to spill out of the tank very fast, about half a quart (half a liter) spilled out in a few seconds, we turned off the engine immediately as it looked it got to a boiling point. Radiator hoses, both top and bottom were cold. There is coolant in the radiator hoses, I can hear them slush, however it seems there is also air inside (can't be sure). Is it possible that the thermostat is stuck closed by sitting without coolant for months?

POST 2Original post

Why are you helping the shop? Why don't they have a vacuum fill system? 3 gallons is just 1/2 capacity. You need to use 5 to 6 gallons if ALL of the coolant was previously evacuated properly.

Get the vacuum assist tool. You will be glad you did and you will use it more than once. It is a solidly reliable way to fill all those darn hoses.

Is the Pelican tool - $87.29 as good as a uView Filler tool that Ahsai uses in his thread? Curious. Schwaben Cooling System Coolant Air Purge/Refill Tool. Used to refill the cooling system without air pocket issues old thread 2013-- https://rennlist.com/forums/996-foru...pump-tips.html
