"transmission fluid leaking from fitting below radiator cap after replacing radiator on 99 surburban
Probably your radiator fluid leaking out.
Antifreeze is green in color and is leaking from your radiator .
It is probably Radiator fluid that's leaking. if you have red radiator fluid. it looks purple when it heats up. I had this from my Toyota Sequoia when the leak went over the hot engine.
put radiator sealer in it or crack an egg in it
If a leak exists, there should be green or red fluid leaking from just under the nose of the car. It is possible that the engine must be running for the leaking to occur, but this is not always the case.
if you have an automatic transmission there should be cooling lines going to the radiator to cool the transmission fluid the lines could be leaking or the tank could be leaking
Green fluid leaking from a car is radiator fluid. "A professional certified mechanic can handle the repair or maintenance needed to fix this issue."
loose/cracked radiatior hoses
Find where the fluid is coming out and repair/replace it.
bad radiator cap
You have a leaking transmission cooler, usually part of the radiator. The transmission fluid is mixing with the antifreeze turning it pink.
looks like a sensor or thermostat going into engine block
If a Mazda MPV is leaking yellow fluid then it is possible that the fluid is brake fluid. It is best to take the car to a mechanic right away.
I wondered the same thing. The radiator doesn't only cool the engine coolant, It also cools the transmission fluid that comes from your transmission through the cooling lines. So your radiator has a crack somewhere and that would explain the transmission fluid leaking out. Hope that answers it. William @ JeepGrandCherokeeTransmission.com
You will notice two lines going to your radiator from the transmission. One is a service line and one is a return line. The radiator has a transmission cooler built into it. If you have trans fluid in the radiator chances are the trans cooler is leaking. A little trans fluid in the radiator will not affect engine cooling BUT as soon as the pressure drops in that transmission you may very well have radiator coolant sucked into the tranmission and that will ruin a transmission in a hurry. You need to get this checked out as soon as possible.
your heater core is probably gone
leaking head gasket or improper fluid in cooling system
check your radiator hoses and change gaskets
The transmission cooler is built into the radiator, and the tubes on the cooler are leaking Trans. fluid into the engine coolant. Need to replace radiator.
It could be the radiator, hoses, fuel pump or an engine gasket. All of those components just "give out" with time.
the trans fluid on a auto trans goes through a tube in the radiator to cool the fluid if the tube has holes in it, it will leak trans fluid in to radiator. you need to replace radiator or have rebuilt.or you could put on a aux trans cooler and put plugs where the trans lines used to go.
If it is leaking trans fluid into the coolant it can cause overheating.
You have transmission fluid lines that go to the radiator/front for cooling you must have a leak there
Heater core would be the likely culprit here.
