Running Hotter after PLM Heat Exchanger instll
the Temp gauge of my My 2002 C32 AMG is showing higher temperatures while driving around now that I have installed the PLM Heat exchanger. I installed it in February and now March is in the 40s. I am wondering if it would go much higher than normal in the summer months. I am wondering what is the culprit? Should I flush it again?

+1. Burping the cooling system is in order. There are lots of videos on youtube. Is it separated cooling or OEM setup?

Nice: i watched some vids,I didn't know about burping with a funnel etc, after cleared lines at what stage do u turn the taps for NW isolate kit during idle or at rest? Any tap first? Cheers Gramma n Lenin

I turned the isolation taps after a few days of driving around. I cleared the air out of the lines straight away. I just wanted to make sure anything else had gotten itself out and was all running smoothly. I did it with the car off, either tap first.

The C32 heat exchanger is self burping. This is confirmed with EC when I installed their HE. That is IF you left the stock lines intack.
Mine required about two days of adding coolant to the over fill tank before it was perfect at the track, aka road course.

Cheers, Will do, Thanking you for the advice tw2. Awaiting "rcompart's" intercooler as mine recently went south. Have put coilovers in and replaced all the front control arms etc. Quaife is on the shelf awaiting install but the IC went before I could finace the install. Its a love hate relationship with this 32. Any issues with the 55? A window regulator perhaps, windscreen wiper blade replacement?
Cheers,

Well there was a service.... and I did need two front bushings replaced to get a warrant (annual mandatory fitness check of car) and they were tossing up on whether I needed a new wiper blade but they couldn't find one haha. So basically no, no problems.
I am still trying to decide whether to go into mods- it would be long tubes, port and polish, quaife, look into cams, intake, dyno tune and TCU tune + paddles and maybe some coilovers. Or whether I do a custom single turbo (very stupid idea) or wait until I can afford a C63 or SLK55 (best idea).

Wow, coilovers will definitely transform the handling for the better! Quaife will hopefully get you a better launch also. What tires are you running? Some drag radials would be interesting with all your mods.

Nitto invo's on front and nt01's on rear: hence the reason for front suspension revamp, coils and quaife....a month or two back I spun out in the wet and straight over a grassy island between a cement pole and tree to opposing road. Very lucky. Pride front,rear control arms damaged only. Lesson learnt.
Slk55 is a beauty but the raw sound of the 63 under load is intoxicating.
It's good to hear the wipers are holding up mate. No excuse not too be juvenile and outlay some fun funds on long tubes and why not at it, a quaife would be ideal.

Did you get the quaife from NZ in the end or US?

I did purchase the Spill Free Funnel and "Burped the Cooling System" twice with it, while tilting the front end of the car (passenger side higher than driver's side) and running the heater while burping the system". I also pedaled the gas a few times to ensure proper circulation. Still no change.

Sorry OP,
Quaife purhased from Rob at NW, I think it was cheaper or almost the same from NZ distributer but happy to support the fabricators that make our life all the more interesting
OP- have you contacted PLM? There is also a product called water wetter that may help..

Great, I remember just pinching the coolant return line and the reservoir bubbled for 30 seconds and that appeared to be about it. I never had any overheating problems with the stock heat exchanger but the PLM one was way heavier and had so much more volume it has to be better. Even just the increased amount of metal creates such a huge heat sink to keep the coolant temps lower while boosting.
