You need to specify your make, model of car. Some cars have Power Steering coolers in front of the radiator and some don't. Most powers teering leaks come from the power steering pump seal going bad which can be temporarily fixed by using an additive like Lucas Power Steering Stop Leak. It's a little pricey but can get you by and has stopped leaks in my power steering units. If the leak or seal is real bad then you will need to replace the pump, and it may or may not have the reservoir attached to it. Most cars do not have the power steering cooler but some of todays high performance cars do and if something has punctured the cooler, or the lines leading to it, then you may need to replace the cooler or hose. Identify your car and try to determine where the exact leak is and then repost for better help.
If you have an oil cooler, it's possible that the lines have become rusted and are leaking.
2004 sedona's have a tanny cooler in the front to keep it from overheating like a small rad if one of the lines are bad or damaged it will from the bumper (front) area
red fluid is transmission fluid and could be leaking from several locations around the transmission. Check the cooler lines where they go into the radiator, the seals where the axles go into the transmission, but most likely is a leaking pan gasket, etc. The only good way to find it is to look under the van and see where the wet spot is located
Transmission fluid.
Rear main engine seal or front transmission seals
What color fluid?
transmission cooler
You have transmission fluid lines that go to the radiator/front for cooling you must have a leak there
Work needs to be performed. Also depends where it is leaking from. If pan is leaking just drain transmission fluid and install new pan gasket and refill transmission with fluid. If front seal leaking then you will have to pull transmission and replace front seal.
Hub seal is leaking
Find where the fluid is coming out and repair/replace it.
Anti freeze. You need to get that fixed. and fast. Check your coolant fluid levels.
