Have a 1979 MG Midget. It attaches to the radiator via a hose and is strapped to the passenger side of the car in the engine compartment. It looks like a canteen, has what looks like a radiator cap (most of the lettering is gone), and is about a quart in size. I assume its for radiator coolant?? When I opened it and dumped it out about a cup of brown "water" came out of it. If so, what should I be putting in there? I bought some of the 50/50 radiator coolant that is already premixed, but I have nothing to guide me. My engine is th 1500cc model. I have driven the car around the driveway and within about 5-10 mins the temperatre gauge is reading Hot. The fan is working and all of the blades are there. I checked that. I assume this is the reservoir and it needs coolant. Again, Thank you VERY MUCH in advance to you guys. Without this forum I would essentially be lost as I am a noob!!
