Engine Cooling problem
1994 Acura Legend 6 cyl All Wheel Drive Automatic 100xxx miles

I have a 94 acura legend and it keeps overheating, the antifreeze is leaking out from behind the motor, the speedometer dosent want to act right and the d4 light is blinking all the time I replace the heater coil hose and the hose from where the antifreeze was leaking from behind the motor and there seems to be antifreeze leaking from the radiator cap, I can drive it for a short period of time before my temperture hands get to the hot spot. What is wrong?

Hi pitbull34,

The speedometer not working and the D4 light blinking should be related and it most probably is a faulty speed sensor.

Check the speed sensor connection, located on top of the differential axle.

As to the overheating, if bleeding of the cooling system was not carried out after replacement of the heater core, do it now to see if the probpem is resolved.
If the bleeding does not resolve the problem, most probably you have a bad head gasket due to the previous coolant leaking and overheating.
