Why is the radiator fluid leaking?
It could be the radiator, hoses, fuel pump or an engine gasket. All of those components just "give out" with time.
Transmission fluid leaking from fitting below radiator cap after replacing radiator on 99 surburban?
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
easiest way is to fill radiator and look and see where fluid is coming out, but Im sure you thought of that. The best way is to plug the ends of the radiator up with some type of rubber stopper then insert blow air through the drainport while holding it under water. Wherever the bubbles are coming from is where its leaking.
What should you look for when a 1994 Mercury Tracer with 80K miles is leaking transmission fluid out of the top fitting of the radiator with no visible damage to bolt or washer?
99 dodge grand caravan you replaced the lower radiator hose but it is still leaking where could the leak be coming from?
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…
There is a rubber hose on the firewall near the heater core that bends down and isn't hooked up to anything It is leaking rad fluid badly What does this tube do?
Why is red fluid leaking from your 1998 chevy venture. it looks like it coming from the front of the van?
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
