Gas A Question (Covered Grill)

[DCMAC214]

Sufficient air flow for cooling?

Saw a front-engine class A coach over the weekend that had the front grill completely covered. I assume it runs on gas but no way to tell seeing we were traveling in opposite directions on I-40.

Our coach has a HUGE space between the (real flimsy) grill and the radiator. Assuming the one we saw was basically the same, even with that space I wouldn't think there's enough air flow for proper cooling.

It is not uncommon for vehicles of all sorts to depend on the air flow from beneath the front of the vehicle to cool the engine. This may reduce flow from moving down the road in which case the fan will spin more often and use some engine power doing it but that may be balanced by better streamlining?
