Also, I replaced the coolant level sensor that sits in the bottom of the coolant tank but still get the flashing red light in the dash.

Update on this I had to remove the transmission mount bolts and slowly lower the transmission to get enough space to get my hand in there to replace the heater control valve.

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.

Hi guys first time poster here,
I bought a 2004 Porsche Boxster tiptronic. I replaced the water pump and thermostat and as soon as I went to add coolant into the system, it all leaked out on the right rear side near the wheel so then I removed the tire and it seems like the heater control valve has separated from the plastic flange. The space is so tight. I could barely get a set of pliers in there to remove the clamps has anyone done this job before that has some tips or tricks to make this job easier? I’ve already removed the triangle brace and cover, but there still is not much access. Is there anything else I should remove to get more space? There is not much information online regarding this, but what I found is, I may need to remove the muffler and lower the engine and transmission. Anyone have any experience with this and can provide detailed instructions?
Thanks in advance.
Update: FINALLY GOT IT OUT!
For those that are tackling this job what I would recommend is to put a jack on the transmission, remove the two bolts on the sides of the transmission mount and remove the subframe bolts and then slowly lower the transmission a few inches and you will have enough space to fit a 45° extended plier in that spot to remove the clamps and easily replaced that valve.
Also, I replaced the coolant level sensor that sits in the bottom of the coolant tank but still get the flashing red light in the dash. Any suggestions on how to fix that? And will be tackling the AOS next so if anyone has tips on that, I would appreciate it.
Thanks all for the help!
