2003 Avensis Heater

[New2Toyota2009]

I have recently aquired a 2003 Avensis. The only problem I'm having is that the heater will not work. I've tried the fuzes and they are in order. After a long run (40 minutes +) I start to get wisps of heat that continue for a short period before dying off altogether again. My fiancee's dad seems to think it may be the thermostat. The engine temperature gauge seems to take a while to start moving (20 minutes) but once it starts moving it goes up quite quickly.

This problem is really starting to annoy me especially with this cold weather we are having, and it's starting to put me off the car altogether.

Any help would be gratefully appreciated.

Thanks in advance.

A duff thermostsat or an air lock would cause such symptoms so it would be worth having both these apsects cheked out first.:)

I agree with Jamesbelfast but would add checking that the heat exchanger isn't blocked by disconnecting the hoses to it and flushing it out. These are the small dia hoses connected to pipes thru the bulkead.

Had the same problem with my 03 Avensis . It turned out that my coolent level was to low .

After topping it up it immediately fixed my problem .
