32Renn

Possibly some of you can help with this , my 32 when driving 45-60mph will get up to 120 deg cel. , is this normal ??? At idle, stop and go, and higher interstate speeds (70 -120mph) all is fine.

I have the following motor upgrades , perhaps it make the difference ?
Renntech Stage 2 upgrade including:
Renntech ECU
Renntech pulley kit
Resonator removed
Green filters

Thank you in advance to all that reply

Is your cooling fan working? Usually it prevents the engine from even getting that hot. Also, do you have enough coolant fluid? Check for a possible leak, maybe your water pump is failing. The supercharged AMGs are also prone to an intercooler pump failure. If you need ro replace it, you may want to consider the upgraded version from Evosport or Kleemann, especially with your modifications.
