I don't know that '91 Mercedes diesels have a cat/s?

I'm going to try that flush product, and remove the radiator and give it a really good cleaning. I'll do the thermostat and probably the water pump. If I still run hot after that, Im going to install an 1600 CFM electric fan on the oil cooler to see if that can help. Turbos add a ton of heat to the oil, so it just might be enough to keep the temp down on climbs.

Im also wondering if my cat is starting to get clogged up. The car seems a little sluggish, but then again, it always did.
