When you say that you have cleaned the 2 front heat exchangers does that mean that you have removed the bumper cover, separated the air-conditioning radiators from the engine radiators and cleaned between them and the engine radiators?

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

POST 1Original post

mu 2001 boxster overheats if i leave the pressure release lever in the normal position. i have cleaned the 2 front heat exchangers, checked the water pump impellers, and the thermostat and replaced the coolant tank cap. i have to keep the pressure release lever up so it won't overheat but it sweats from the coolant pressure - please give me some insight on why it overheats when it is pressurized - thanks __________________ This post was auto-generated based upon a question asked on our tech article page here: Pelican Porsche Tech Article - Coolant Tank Replacement - Porsche 911 Carrera - Porsche 996 Carrera (1998-2005), Porsche 997 Carrera (2005-2008)

POST 2Original post

Sounds like you may have a faulty head gasket. Especially if you have confirmed all other cooling system components are functioning. Double check that there is no air trapped in the system. If not, check the cooling system for C02, this is the best way to test for a head gasket. - Nick

POST 5Original post

The bail is a vacuum break not a pressure relief lever. It, the square plastic shaft, is up when the engine is hot, bail flipped or not. The bail holds it up to allow pressure equalization as the engine cools and burps the cooling system.

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