I recently fitted a YD25 engine in a Navara, I had seen the engine running and it drove fine around some private ground before I bought it. Once fitted and on the first test drive on the open road I saw the temp rise so let it cool and brought it home. Temp gauge didn't go into the red. I replaced the waterpump (properly knackered) and it runs fine now (no overheating) but I cannot get coolant to circulate through the heater. I've flushed the system several times, raised the front of the jeep when refilling the cooling system but to no avail. I temporarily fitted a pump on the output of the heater and could get coolant to flow with it, but once remove it's back to the same old tricks.
Am I missing anything?
