Anyone know what size is the air tanks on a Sceniccruiser? I found 2 of my air tanks have rusted through and expect the others are not far behind. I want to relocate and install new tanks in the engine compartment. Does anyone know of any reasons I should not put them back there? |

Ted you might want to leave the tanks where they are as GM spent a lot of time and effort finding the place for them. it will save you a lot of time and money by just replacing the tanks in their same location. contact MCI or your local truck parts supply and they should be able to get you the samde size tanks. |

Hello Ted.
The only thing you need to be careful of, is that you do not accidently change the brake application timing by dramtically lengthening the hoses supplying the relay valves, or that you restrict the air flow by choosing a small hose, or restrictive fittings.
With the age of many of our coaches, and the number of owners over the years, one cannot trust that what is currently installed is doing the proper job.
It would be a good exercise to be sure that the tanks are the right sizes, the lines are the right inside diameter and lengths, the proper valves have been used, etc.
Best to know for sure, rather than trust a previous owner or mechanic.
happy coaching!

Trailer brakes on semis use relays and their own air supply tanks because of the long distance from the cab.
In other words, as others have already said, a long distance from the foot brake (air valve) means a long delay in brake application and release. This is obviously not a good thing. |

The air tanks should be kept away from any heat source. The norm is outside and subject to cold air exposure. This is because the tanks are designed to cause the inherent moisture to condense and fall to the bottom where it can be drained and/or ejected. Otherwise the moisture will migrate downstream and adversely affect more critical components.

Yes every one is right. DO NOT put them in the engine compartment.
They need to be cool . I dont know about your tank but on a 4905 one is a two compartment tank so you may need to find one off a GMC.
