It could be Transmission Fluid. Many transmissions are cooled by running a line through the radiator. Check for small tubes going into the radiator, if you only have the two large engine coolant lines, you don't have a transmission cooling line in the radiator.
Crude oil is about as different as cheese. Varies a lot. color is black/brown,water white,dark green,reddish etc. it depends upon the components it hold (As lighter components it hold as lighter in color and as heaver as dark it will be) density is between 700 - 1000 kg/cum and kinematic viscosity can be anywhere between 1 and 8 cSt (centi stokes)
SATURN
you can't ^WRONG from the research i have done so far, you can use camote tops as a pH indicator gather the reddish leaves, boil in some water then pour it through a sieve. The liquid you get acts similarly to what you get with cabbages. They turn pinkish-reddish when exposed to acids and bluish-greenish when exposed to bases
your diaphragm is a reddish color
reddish-brown
trans fluid
It may be something else, but transmission fluid is reddish, or should be. Bob in AZ
Yes, at room temperature.
Break fluid is a possibility.... Do not use the car until a qualified mechanic has checked it out.
myoglobin gives the muscles the reddish brown color
Usually automatic transmission fluid is a reddish color. If you see red fluid on your driveway, then you probably have a transmission leak.

Without any other info I'd say you have a bad headgasket or a cracked head/block. Generally oil has to be pressurized to show up in coolant, or the reverse would be true and you'd have coolant in the oil also making it milky white. So... oil is leaking from somewhere pressurized to coolant.. Pressurized oil only comes up to the head in one passage, and that has likely developed a leak to the nearest coolant passage, most likely through a bad head gasket. This is more likely if it's been recently overheated. Some vehicles have an internal oil cooler located in the radiator. If this cooler has a leak then you will get oil in your radiator. If the fluid inside the radiator is a pinkish, reddish color the it would be the internal transmission dooler in the radiator
yes it is reddish
RETINASPHALT', n. A bituminous or resinous substance of a yellowish or reddish brown color, found in irregular pieces very light and shining. [See Retinite.]
The population of Reddish is 30,055.
Check your transmission fluid levels. Look around for leaks...you'll see a reddish fluid around the drive axle on your transmission or around the radiator.
