Peugot 406 Engine Temp Too High

Help!
I recently bought a 1999 Peugot 406 3.0 V6 with 82,000 miles on the clock.
After sarting the engine and driving about 10 miles, the Stop light on the
centre console comes on, the screen reads Engine Temp Too High and the fan
comes on at maximum. Both temperature guages read normal. The Peugeot
dealer has checked it with their diagnostic tools and tell me there is
nothing wrong. My local garage is also unable to identify the problem.
Since buying the car, the computer has been reset, I have had a new
radiator and a new temperature sensor cluster fitted as well as a new
timing belt.
I would be most grateful for any ideas as I am worried that by just
ignoring the message may be doing damage for which I will pay dearly for
in the future.

 

If you recently bought it, then take it back.....

Or was it a private sale.

Sorry, by recently I meant several months ago. The guarantee period is long
since over.

 

If purchased in the UK you have an automatic 1 year guarantee anyway, no
matter what the dealer says.

If he refuses to sort it, take him to small claims.

Stolen from another forum.....

Today I took the family to my brother inlaws in Mountain Lakes NJ (about 85

Thanks for that, I'll have a check. However, the problem isn't that it is
overheating, more that it's telling me it's overheating. I'll see where I
stand about the guarantee, but I always thought it was 3 months and then
you had to pay.

 

Maybe in some states of America........ not in sunny england unless it was
sold as seen...

Keep us informed if it works 'cos I'm just a couple of K short of 82k. And
my V6 runs hot.

 

We had this problem early on - turned out to be a temperature sensor
problem and the normal diagnostics seemed to pick it up without any
difficulty.

A search under temperature in this group would turn up a mass of
information on this problem - don't limit it to 406.

 

You say the fan comes on at full speed. On Peugeots fitted with two fans
they should both come on at the same either at slow speed or high speed. If
you only have one fan working the cause of this is your problem.

 

Cheers, I'll check this out.

Thanks, a faulty fan sounds like the problem as it happens with or without
the aircon on. I'll have a check and let you know.
