The lack of redundancy with one puller fan makes me nervous for a DD car. I've replaced the fan and fan clutch every 40-50k with zero issues and I see 100°F+ temps from May through September and hard freezing through winter. I'd love to know how may folks have a spal setup like this with significant miles on the E fan puller setup.
The fan in front of the car is for the a/c no need to have removed it. Now your a/c won't cool well especially in town. It also is a safety fan and runs when engine gets overheated.
Surely having a radiator shroud would make it more effective as there's large parts of the rad not covered by the fan, so the air won't be getting pulled through it. The Z4m doesn't have a viscous fan like the m3. And surely the viscous fan causes some parasitic power loss
I have an electric fan on my e46 m3 do you think having the fan and the aux fan cause interface with cooling. I live in Texas and we hit 110 the other day and on the highway oil and water Temps went up not getting to red but Def hotter. But when I stopped at a light Temps went back to Normal lol.
