Relays?

[davidf]

Well I'm changing some relays due to age although they all work. I've replaced main/fuel pump, but Acura dealer here does not have a clue as to where the radiator fan and AC condensor fans relays are and I've found nothing marked "radiator fan" or "aux. fan." I've found fuses but no marked relays. Anybody know. Huge thanks.

according to the manual, the radiator relays are in the middle relay box in the picture below(#6). You should check out the manual, it's all there.

The item 005 37735-PR7-A01 CONTROL UNIT, RADIATOR FAN is a control unit and does not contain the relays which switch the "big" currents to the fans. Relays could get fouled by electric arcing which eats the contact material over time.

See page 23-112 of the downloadable Service Manual (is available on the NSX Prime website in PDF). Or click here:

Your relays are in Sub Relay Box A as member ak has pointed out.

This is the reason I'm replacing them NOW. I feel it's a great insurance policy and a very small investment to replace them here and there to keep myself from being left stranded down the road. I personally think everyone who buys an older NSX should immediately replace the "main" relay.:smile:
