I have a 2.4TD EFI Super Custom Limited
Engine Code 2L-TE
It was parked up for approx 2 Years and I put a battery on and she started straight away.
However, I noticed the Digital Temperature gauge jumping around from mid to hot so I changed the Temperature Sensor.
This helped a little, however it still would go to Hot suggesting that the Hiace was overheating and there was no hot air from the Heater Blower!
So I replaced the Thermostat and still same problem.
I ran the Hiace without the Thermostat and she didn't overheat and there was still no hot air from the heater blower!
I flushed the whole system and even flushed both front and back heater matrix with the garden hose, which had some dirty water!
I filled her up with 3litres of anti-freeze and water, ran her till she was hot and capped the radiator making sure she has no air locks.
However she still is overheating according to the Digital Temperature gauge! and I am still not getting hot air from the blower.
I have felt all the water hoses and matrix hoses and they are all hot enough, so she should give hot air into the cabin, but doesn't.
I don't think it is the headgasket as there is no water and oil mixing and she doesn't seem to lose water.
So can anyone help me solve this mystery?
Thanks and I look forward to your replies and ideas.
