your heater core has an internal issue. if that is not it, then its leaking into your oil, an easy way to check that is drain a small glass cup full of oil. now oil floats on top of radiator fluid so if you have any discolored part of fluild in the cup then you have a blown seal in the engine. but this is a "just in case" type of thing, i doubt it happened to you. but the easiest way to get this thing solved is run a diagnostics on it, autozone is free, and even though nothing shows up on the dash, the computer might know something you dont
pressurize the system. that'll make the leak leak faster and you should be able to find it easier.
Leak in heater core
Check the oil pump housing gasket
i would say either a leak would cause a puddle underneath, or if you parked ontop of a spot of fluid that was already there before you arrived.
it depends if it is a metal line or rubber lines , if it is at a fitting or at the master cylinder or abs i can help you find these if you cant locate the leak
you use a mirror and a flash light
Because you have a leak, or you parked over a puddle of someone else's transmission fluid. If it is from your car visit your local dealership otherwise park somewhere else.
You cant
A puddle of dirt is a puddle of water with a dirty-like effect to it. It can be found after a heavy rain by large amounts of dirt or sand. You can find a puddle of dirt on the sides of roads or on baseball fields. I hope this helped! :)
Perhaps the radiator itself or lower hose - try pressure testing system to find leak
Look at the under carriage and check the ground where the vehicle is parked for a power steering puddle or stain.
wait for the rain and drink from a puddle
