* Automatic Transmission Fluid (ATF): This is the most probable cause. Automatic transmission fluid is typically red, and leaks often originate near the transmission itself, which is located towards the front of the van. Leaks can stem from a failing transmission seal, a cracked transmission pan, or a worn transmission cooler line. This is a serious issue requiring immediate attention; driving with low ATF can severely damage the transmission.
* Power Steering Fluid: Power steering fluid is also often red, though the color can vary. A leak could come from a hose, the power steering pump (located near the front of the engine), or a leak in the power steering rack (closer to the wheels). Driving with low power steering fluid will make steering extremely difficult and could damage the power steering system.
* Coolant (unlikely, but possible): While coolant is usually green, orange, or yellow, some formulations are red. A red coolant leak could indicate a radiator leak, a hose leak, a water pump failure, or a problem with the engine block itself. This is a serious problem that can lead to engine overheating and damage.
You should NOT continue driving the van. The leak could cause significant and costly damage if ignored.
To determine the source:
1. Identify the location of the leak precisely. Take a picture if possible. Is it dripping from a specific component, or just generally from the front area?
2. Check the fluid level in your transmission, power steering reservoir, and coolant reservoir. This will help narrow down the source. The owner's manual will show you where these reservoirs are located.
3. Consider the smell and consistency of the fluid. Transmission fluid has a distinct smell. Coolant is usually somewhat slick.
Get it checked by a mechanic ASAP. This is not something you should attempt to diagnose and repair yourself unless you have significant automotive experience. The sooner you get it checked, the less severe the damage (and cost) is likely to be.
