Review on Hella 12V 5-Pin 0-900s Delay On Time Control Unit 996152151 by Brandon Peters

Works like a charm! I bought this relay to start the electric radiator fan about 30 seconds after the engine starts so it doesn't draw as much current from the battery. Typical Hella quality, made in Germany. Much better than cheap relays from China or elsewhere which have smaller electrical contacts inside (after disassembling various relays) which cannot handle the rated current. I just wish these Hella time relays didn't cost so much. But then again, if you want a quality, well-made part and not junk, it's going to cost more these days.
