Welcome to the Feroza overheating brigade....

Lots of info available via search.

Candidates

Thermostat - use genuine
Fan - refill with silicone fluid / lock it / replace it / electric thermo & shroud
Clogged radiator core - flush /replace
Water pump - a lousy design in the first place... electric pump

The HD cooling system always seems to present problems - poor water circulation in the block made even worse by the water pump.

Start with the small things

I cut and pasted this from a thread I had running recently with similar problems. The electric water pump isn't necessary and now I worry that the car isn't hot enough as it runs REALLY cool.

UPDATE.

The re-core radiator went in and still it overheated.

Thinking the thermostat was fine after testing it in a saucepan I hadn't actually tried running the car without it until today. Well that was definatley the culprit. I've never seen the engine run so cool.

I was a bit dissapointed with the flow from the electric water pump until I tried it without the thermostat in. It now looks like a river flowing through the top tank.


So if your Fez is overheating this is what I did and the cost:


1. clogged radiator
Re-cored the radiator - $275. Twin core with the fattest tubes that could fit.

2. defective thermostat.
You must try running the car without the thermostat for a proper diagnosis. I will try and fit a new ORIGINAL thermostat soon. Cost should be no more than $50

3. defective water pump
Checked original water pump and that was fine. Fitted a Davies Craig electric pump for $165.

4. Defective viscous fan
Re-filled with viscous fluid from Toyota - $30

5. crack engine
I have one now after running too hot for too long. This was not the cause of overheating in my vehicle although it will now need to be fixed.

Total cost of getting the car back to cool - $520

Now I have a lead on a new and better engine, extractors and exhaust so soon the Feroza will be well and truly back in time for the mud
