ka24e coolant not flowing. cold lower rad hose - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

240sxrb25 · 10-03-2009, 10:20 PM

i have a 1990 240 with the ka24e and the car takes a very long time (30 minutes) for the heat to work at its best. the heater core is not clogged, the radiator is not clogged, new water pump, new thermostat.

the lower radiator hose never heats up at all, but the upper is very hot.

im out of ideas, why doesnt the lower hose heat up, takes so long to create good heat inside the car.

thanks

make sure you properly bled your cooling system, there may be a air pocket. and are you sure your thermostat is opening up? any signs of overheating?

doesnt ever overheat.

i had the front of the car in the air running for like 15 minutes today squeazing tubes. i cant gt any more coolant in. only about a gallon went in

did you raise up the front of the car and run the heater while you were bleeding it? as long as your not overheating you should be fine.
