Small fans behind engine compartment side vents?

[6cuda6]

Anyone ever put fans behind the engine compartment vents to help ride the engine fumes/heat after shut-down (perhaps while in traffic as well)? Kinda
like venting the engine compartment on a carburated inboard engined boat.

Yes, it's called a bilge vent evacuation fan. Yes, I have seen a couple
used on Motor Homes. Not a bad idea, but it would pull fresh air into the
engine compartment, I might consider whether it is a good thing in the
event of an engine compartment fire.

Seen that use back in 1985, but the vents w/o the blower won out.

Do the vents really work well? Im more interested in the time "just after" the engine is shut off and everything is cooling down....so all the fumes
are getting trapped under the engine compartment area because the wife hates that "old car carbon/fuel" smell.

I can’t speak to the effectiveness of engine bay fans but we (she?) were not too happy with the stink of shutting down a hot 455. Our solution was expensive but SOOOO worth it. I replace the carb with a Howell kit including the electronically controlled distributer and an EBL.

We had chased this for the longest time, starting with safety - new fuel lines, then an electric fuel pump, carburetor repair after repair, no luck. Carburetors are just not my thing anyway, so I finally came to the conclusion that we’d need to replace the carburetor with either a quality Patterson unit or go with EFI. No looking back, this is a great upgrade. No more stink when we stop and she purrs like a happy kitten.

If you have replaced all the fuel and Vent lines you will not get the smell.
So many have felt they know the emissions system and have screwed it up.
I’m a firm believer the emission system does not hurt performance.

Larry,
Do you have a reference source and instructions for the Howell kit?

Agreed Jim....i have no need to alter the emission equipment. I do have to upgrade all my fuel lines and vent lines but want to get as much heat out
as possible.

Seeing as how im upgrading things and the coach wont be back on the road till next year do to my work schedule nows the time to do all these things.

Since I live a stone’s throw away from Jim K I bought the whole Howell kit and EBL from him. I’ve never regretted buying from our vendors!

"I'm a firm believer the emission system does not hurt performance."
I agree with you JimK. So much stuff gets ripped out because people don't understand it. No downside to good evap emissions control. Thank goodness
we don't even have EGR as people would want to remove that to "go faster". They don't realize it's out of circuit at heavy throttle, just like AC
clutch is off at heavy throttle on cars since the mid 80s.

I read, ON HERE, someone bought an electric radiator fan and installed it to blow OUT of the front grill, it was mounted in front of the radiator.

I think he had a switch to turn it on, and a thermostat that shut it down when the engine compartment cooled down.
Said it didn't take long, 10, 15 minutes to pull all that hot air out and shut down.

Someone probably knows who this was. Be careful though, those electric radiator fans are usually high amp motors so know what you are getting into.

From a serve standpoint, we hate ALL the junk people pile on the coach.
Obstruction on front of the radiator is not good as it dos more harm than
good.
