I’m in the process of refreshing the coolant system on my 94 4.0 AJ6 coupe. Bought a hose kit from one of the usual suspects, aluminum radiator, fan clutch, thermostat (OEM ouch), rebuilding the fan cowl with rubber flaps since the cardboard flaps are not flapping as I think they should and a heater control valve.
There are two hoses (5/16) which are part of the system which were not included in the hose kit. One runs from the rear of thermostat housing to a 3 way fitting between cylinders 3 and 4. The second one goes from the rear of the throttle body to the same 3 way fitting.
I could not locate these hoses on any of the parts sites. I’m certain fuel line may work but not sure about temp rating. I also found at my FLAPS 5/16 transmission hose which I’m tempted to use.
By the way, I had to remove the throttle body to gain access to the B#####d hose but did not have to remove the intake. The TB shocked me once removed. I’m surprised the car idled at all. I’m going to have to look at the IACV to see if it is in good shape. I can see no light around the TB plate and walls.
I’ll show an after picture once cleaned up. Didn’t somebody here do a catch can to help this issue?
