High Coolant Temps

Sup fellas!

I recently installed a K04 kit in my 2011 GTI with a plethora of supporting mods. It runs great and strong but I'm noticing the running coolant temps jump to 220 or higher sometimes when I am in the city with the A/C on. The fan kicks in hard when it gets above 220(I'm reading the temps via the Torque app) and it will run for a solid 5-10 mins after I turn the car off.

I'm wondering if its common or should I be looking into a better radiator or is this a sign of a water pump starting to go?

Thanks!

Whats the highest you've seen? 220 is fairly typical. Ive seen that on warm days especially in the city.

227 is the highest I've seen it. It regularly gets to 224 when I'm hot roddin in the city. My brother has a Mk6 GLi with the same mods and his never gets above 210 so it has me wondering...

Flush your rad, add new coolant and bleed the air out. OR thermostat???

Torque reads like 10-15 degrees higher than the actual temp, I use to run it till I got my Cobb AP and VCDS.

Interesting. I have Torque, OBDEleven and VCDS. Ill compare on my lunchbreak. I know theres multiple coolant temp measurements in VCDS, like radiator outlet, inlet etc. I wonder what Torque reads off of.

I was comparing my measurements today. The G62 coolant temp sensor in obdeleven and the torque reading seemed to be the same. I saw temps go from 204-220 after car was fully warmed in mostly stop and go traffic on my commute home. 82F ambient temp. It liked to sit around 204 when cruising though.

This is good news to hear guys!

When I did the K04 install I lost a lot of radiator fluid and replaced it with half a gallon of 50/50 G13.

I was looking at getting a performance radiator but I'll do the radiator flush first and see if that helps.
As a side note, I will say that when I installed the CTS intercooler I noticed the car gots hotter quicker. I'm wondering if the thicker IC doesn't allow as much air to flow through the radiator considering the radiator sits behind the IC.

Is there an after-market thermostat that you know about that opens fully sooner?

Why though? 220 aint that bad.
I regularly sit at 210sih normal driving and sometimes 215-220 while in heavy traffic.

What intercooler are you running? Front-mounts (in front of everything, especially if the OEM sandwich mount IC is left in place) have been known to cause higher coolant temps due to the airflow obstruction that they are.

Yep this has been my problem on the track. I'm switching to a sandwich mount IC this year and adding an oil cooler.
