406 V6 coolant

Hi,
just bought a 1998 4dr v6, driven it for 250miles and now the coolant
level light comes on from cold,flickers, then goes out after 1-2 mins.
Naturally I'd like to visually check the coolant level but can't seem to
see the expansion tank (seems to be tucked deep into the engine
compartment so I can't see it? - or am I looking in the wrong place?!).
Any advice on how to visually check the coolant level on a V6? I didn't
get a manual with the car. Hoping it's just a dodgy light! Coolant temp
seems to be fine by the way.
Thanks for anyones help,
Matt

 

Isn't it just in front of the O/S strut mounting adjacent to the power
steering reservoir?

 

The coolant reservoir is on the o/s between the power steering fluid
reservoir and the screen washer fluid reservoir. I noticed with mine that it
only needs to be slightly low to make the warning light flicker, especially
under acceleration. It is as far as I can work out duee to the sensor being
built into the reservoir cap. I think I'm right in saying that the radiators
are prone to leaks, I certainly know mine has been, but it's a real simple
job to replace them. I did mine myself and it took me less than 1/2 hour,
also not as expensive to replace as you might have thought, cost me about
£85 for a new one.

 

Supposing you've found it, just behind the washer filler. Mine requires the
odd drop every other month. About a half litre or so having done 2k. But it
is noticable if I've parked off level after the 2k mentioned. so I just top
it up.

 

Thanks for everyones help - could just see the water as I shook the car, so
filled it up to what I guessed was the cold level (I don't have the car
manual) which was about 4inches down from the cap? Anyway, the warning
light went out so I guess it's OK. Will keep a eye on it though.
