Can't get normal temperature

So my 2001 c4 cab is at 170,000km. This summer I decided to do spark plugs, coil packs, water pump, coolant flush and AOS. I am now not able to get the car to sit at or around normal temperature. I'm located in Toronto, Canada. We have had a stunning and hot summer but that's no reason for the engine temp to rise! Does anyone have any suggestions? I used vw/audio coolant. I was told it's the same as Porsche. 50:50 mix. Any tips are much appreciated!

Does the car have an aftermarket front bumper? Have you cleaned the debris from the front bumper thats sucked into the area by the fans?

How much coolant went back in? Does the tank seem full?

Make sure all the fans are running, Had a blown fuse when I bought my car, one fan wasn't running

how did you refill? Any chance air pockets in the system? What kind of water pump? I had an autozone pump fail out of the box.

I have stock front bumper. Bumped has been removed to clean rads and condenser. I can't remember the brand of water pump. I ordered it from pelican parts. I made sure to order the right one. I don't like using cheap parts. I'm leading to think it has to do with the coolant. My mechanic is a Benz mechanic. This is his first p-car. I will check the fuses. Other than the temp. Car runs tight and no p-codes.

You have checked the radiator ducts and they are clear. Both fans are working ok and you have confirmed this by checking that both are blowing about the same amount of hot air out? There may not be a problem. For one thing you are using the in dash temp gage and it is notoriously imprecise. If you are really interested buy a good OBD2 code reader/data viewer/logger and monitor coolant temperature in real time. See what the coolant temperature actually is. I have done with with my cars and for instance my Boxster's coolant temperature can climb to 226F under high ambient temperature conditions and in some cases reman there for hours and yet the engine is just fine. Driving in real high (116F) ambient temperature -- this years ago with my Boxster -- the temp gage needle went across the gage face to an area it had never been into before. The radiator fans were running full blast all the time as was the engine compartment fan. Ambient air temperature was 116F. Intake air temperature was 135F. Coolant temperature was 226F. Drove from AZ to home -- MO -- with no drama which should have told me all was ok, but back home I checked in with the Porsche dealer and the SM took down the info and passed it on to the factory. The word back from the factory was with no warning light on there was no problem. Pretty much confirmed the coolant temp gage is more for show than go. Might add this was years ago and the engine has been just fine now with currently 293K miles on it. Thus in your car's case the temp gage needle is a bit further to the right than it has been before and you point out the summer has been "hot", and there could be nothing wrong. As long as the coolant level is ok, doesn't change, and the temp gage needle doesn't continue to climb and the dash coolant level and temp warning lights stay dark I'd say you have really nothing to worry about. But keep an eye on things. There could be a problem brewing. I note you changed the water pump, but did you change the T-Stat? If not the old one could be failing, sticking partially closed. This could lead to the engine running hotter. Or the new one could be "bad". Or the new one could require a bit more temperature to open as much as the old/original one so the engine runs a bit warmer -- by the temp gage -- than it did with the old T-stat. (This is what happened with my Boxster after I had the water pump and T-stat replaced. Based on my recollection of where the temp gage needle hung out before and after the T-stat change it appears the new T-stat has the engine running a bit warmer, by just a few degrees. Nothing to worry about as this has been the case now since 172K miles and the engine now has 293K miles on it.)

Thanks for the words of wisdom! I look forward to racking up as many miles on my ride as you have!

Hey, BMANTDOT. Im just north of the city and I've had some hot temps too.. some days with traffic I was getting the same temps you are. I also just changed out my water pump and thermostat, and as the days cool off I'm still just past the 80. Im starting to think it's normal. My engine fan has only kicked on a few times when it was high 30's a few weeks back. See you around, Zak

Good to know! Thanks. On a side note. Just stopped in at pfaff Porsche to buy coolant to do a flush. 60$ a gallon! I didn't buy it. What are your thoughts?

I doubt it's your coolant. Have you checked the following: - coolant tank cap p/n ends with .04 (the latest version) - radiator fans on both sides LOW speed (just turn on your a/c and place you hand on the ground right in front of the front tires and you should feel the air flow) - radiator fans on both sides HIGH speed (use Durametric if you have access to it) - coolant temp read out from the climate control console corresponds to the temp gauge?

Assuming you did this, but to add on, did you bleed the system? You might have air in there. We have a coolant DIY here that goes over the bleeding process. If memory serves me correctly, the system can get a lot of trapped air in it when flushed.
