Clean those radiators and condensers!

I'm currently testing thicker flyscreen in my bumper air inlets to keep dirt out - got that idea from various 4x4 forums, apparently in african regions not uncommon to do.

I have to keep an eye on the temps, it may work as well for slowing down rock impacts....

further testing is needed.

Having the DPF sitting right in the engine bay may be beneficial for DPF regeneration since its sitting near the manifold, but its not beneficial in terms of added heat in the engine bay, pretty sure it affects the condensers ability to exchange heat....

the coolant radiator sits between the condensor and dpf, and the dpf is heat shielded. Air flow goes intercooler > condensor > coolant > dpf.

Don't see the dpf having any influence.

I had the coolant temp drop 15 degrees just by cleaning the AC condenser and radiator. Now my little Pontiac Solstice coolant runs in the upper 190s instead of 215. People that are boderline overheating always forget about the simple but 1st check when troubleshooting. Clean the coils 1st before you do anything else.
