MCI-9 - What is this tank?

Kwajdiver · March 25, 2007, 10:18:05 AM

Located in the left side of the engine compartment. Behind the left tail lights, is a SS tank, about 15 or so gallons. It has a filler tube and cap left of the engine, pointing toward the rear door. The tank is empty, best I can tell.

What is this tank used for?

Thanks for the help.

Bill, can you post a photo of the tank?

Some NJT's had an optional reserve oil tank there so the driver could add oil to the engine just by opening a valve on the bottom of the tank.
Maybe?

Chuck,

Took the photos, was not able to post them....

This tank is located between the air cleaner and back of the tail lights.

MC8 has a reserve oil tank mounted above the engine on the RHS. Tap below and hose leads to block for topping up oil.

This tank is below engine level and looking in the engine compartment is on the left, (driver side).

Thanks for the input,

Bill

like a drain canister for catching blowby and other dripps

Kwajdiver · March 26, 2007, 03:02:48 PM

Okay, not below, somewhat even with the engine. Not a blow by catch.....

This tank is located driver side, rear side door, to the right of the large air cleaner....

The hose out the left side, double back up to the tank. Is plugged and hanging on the tank. Notice the other larger hose mounted on the side of the tank. Not a clue what that is either....

I'm sinking here, someone throw me a life line.......

Bill,
Have you tried opening the cap and sticking a piece of hose to the bottom of the tank and removing it to see what (if anything) is on the hose? Jack

I have a tank and filler cap that looks like that on my Eagle it is for antifreeze it goes to the cooling system.

Could the tank have been a fresh water tank? Was your bus an entertainer in its earlier life? May have had a wet bar or kitchenette.
Stainless would have been used for water storage?
The large pipe looks like an overflow with a check valve. Maybe for pressure filling.
The location would be unusual for a reserve oil tank. They are usually on the RH (curb) side of the coach. Being right over the muffler, seems that whatever was in the tank would be fireproof....like water.
My SWAG for the day!

Guys,

Will do as Jack suggested. See what's in the bottom.

Could this have been a holding tank for clean water for the bathroom? Would have required a pump....!

why don't you just trrace the hose that goes out the bottom and see where it goes.

Coolant Recovery Tank
Part of a system to recovery coolant or add coolant to system. They used a pump to do this. Cooling system overflow goes into this tank and you maintain a level in this tank by adding coolant to it. With a telltale light on dash and a telltale light and test switch on remote control box in engine compartment. Low coolant sensor in the surge tank are used, in conjunction with the automatic pump controls. The recovery tank is not pressurize. When the coolant surge tank falls below a certain level, the coolant sensors activate the pump and telltale lights. this automatically fills the coolant system. Low sensors in the surge tank are also used, in the control of the automatic pump. After 1989 the recovery tank was located below the AC compressor on right side.
