We checked all of the part numbers for everything and they were all correct.
Leading evidence: 'Check of the part numbers' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check front fan operation' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

We did not use a vacuum system to fill the anti-freeze because shop has had problems with damage to the radiators, but we filled system, raised rear on lift, ran engine, refilled until all air seemed out of the system.

Solution - had water pump replaced along with thermostat, both roller pulleys and new belt tensioner plus new Vbelt and changeover from green anti-freeze to new pink variety.

With the new water pump and the replacements made the car temp has changed dramatically.

We also replaced the short hose coming from the left side of the water pump.
Combined work: Replace water pump + Replace water pump still no

We replaced the water pump still no change. We replaced the water pump again with the turbo version of the water pump (pulley 5mm smaller - faster rotation - impeller and all other specs the same) no change.

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.

Car - 2000 C4 cabriolet, 6 spd manual transmission with 80,000 miles - all maintenance always completed on time - car in excellent condition
Symptom - water pump began to leak
Solution - had water pump replaced along with thermostat, both roller pulleys and new belt tensioner plus new Vbelt and changeover from green anti-freeze to new pink variety. We also replaced the short hose coming from the left side of the water pump.
Problem - Since I had this car, it always ran a shade over the 180F mark on the temp gauge. This corresponded with the 83C thermostat (181.3F). Rarely did the temp go higher even when I drove aggressively at high RPM's. With the new water pump and the replacements made the car temp has changed dramatically.
1). Normal running temp is now about 15 - 20F higher than before
2). When car gets hot (still well within operating range - never near the red line for temp) the ability to cool down seems impaired.
We checked all of the part numbers for everything and they were all correct. We replaced the thermostat and no change. We replaced the water pump still no change. We replaced the water pump again with the turbo version of the water pump (pulley 5mm smaller - faster rotation - impeller and all other specs the same) no change.
We did not use a vacuum system to fill the anti-freeze because shop has had problems with damage to the radiators, but we filled system, raised rear on lift, ran engine, refilled until all air seemed out of the system. Over the next 3 days what air was left worked its way out of the system and we added perhaps another pint. All was stable with the coolant level after that.
Left & right air inlets are clear as are the faces of both radiators - no debris.
Car has been driven for about 200 miles with no problems except now has a operating temp noticeably higher than before and mechanic is concerned and baffled.
Can you shed any light on this situation?
Keep bleeding/purging the system. Also check for front fan operation on both radiators. Don't recommend changing from factory coolant to "green" coolant. Hope system was drained and flushed, they don't like mixing with each other.
