Overheating on track only

**shimmy** · 06-07-2012, 10:16 PM

So what I need is a reply from every owner who has tracked their CSL under what can be described as hot summer conditions.

The overheating I am asking about is the type that happens on a hot (23 degree plus) day, after the car is well warmed up and the engine bay is heat soaked. As you then give it 100% throttle (this hallens when circuits have soem straights) The car will then start to have rising oil temps say up to 2/3 and then the water temps follow up and above 3/4 and rise towards the red if you let it.

If you come off the throttle within 1-2 corners the water temps drop quickly.

The question is designed to see if 100 cell cats cold be responsible for this. Please don't answer if you don't have an first hand answer

I was at Circuit de Bretange last year temp around 28 degrees, and oil temp went to 125 but water no problem, does this help my oil temp when on track rises to 125 all tracks.

I'm afraid to reply but I'll do it anyway

I don't have the CSL long enough to comment but I had an e36 track car which was quite the weapon, and, it had similar symptoms to this.

The cure with these things is usually quite simple, just buy a new OEM cooler. They get so clogged up with gunk over time and get their cooling fins all bashed in from stones.

I looked in to modified 13 row coolers etc and in the end A new OEM cured it.

Temps never went above have way doing 20 laps+
