Timed Relay's

I was wondering if anyone has ever heard of a timed relay that would let my electric fan run for about five minutes or so after shut down, you know like the imports do.

If anyone has any info on them or a donor car set up let me know what I need to get or buy, and the proper way to install it,ie..wiring charts or diagrams.

Thanks.

juveteach,

what you want is an off-delay timer. you could check with an auto supplier or an electrical wholesaler to get one. that kind of relay switches state when it is energized, so when the engine gets hot the temp sending unit will switch and the relay would change state causing the fan to come on. when the engine has cooled enough the temp sending unit will switch off - this is when the relay starts timing. the relay will time out and then switch back to normal state (off).

hope this helps.

JB

You could just connect your fan power lead directly to the battery, and the temp switch in your block will keep the fan going until the block cools down enough.

If you are handy with a soldering iron, you could try the cheap alternative.

I use one on an small auxarilly pump (set for 2 mins on time) after engine shut-down.

If you want a neat little aux.pump, check this one out, fits in heater hose.

I love auto shut-off devices, as my brain seems a tad slow these days.

What about a defroster system? Are they timed, or do they work on resistance/heat build-up of the defroster lines?

You could wire up a standard bosch relay with a capacitor on the switched side, but I think that would be one heckuva big capacitor..
