Hi there,

About a week ago, we got a warning on the dash that our Pic had overheated...sure enough when we checked the top up resevoir, there was very little water in. No probs top the water up...off we go again!

Unfortunately, that wasn't the end of the story! Yesterday we saw some steam coming out from under the bonnet. It seems my wife had thought it best to top up the water more through the week & had forgot to put the top up resevoir cap on! (luckily it was still sitting in the engine bay where she'd left it!). So we topped up the water (it took over a litre) and off we went again. Unfortunately now we can hear a muffled gurgling/boiling sound (in the water resevoir top up area)...also the temp gauge is showing three segments (normally just two)...most alarmingly we've seen the temp gauge spike up to maximum & then just as quickly drop back down to 3 segments.

We have a long journey next weekend so are understandably a bit anxious....any top tips gratefully received!!!

Thanks,
Shakey.

Cylinder head gasket failed

Thermostat stuck

Radiator temp sensor duff

Header tank seal failed

Thanks for the quick reply...

>>Cylinder head gasket failed

OUCH! Wouldn't this have other symptoms....poor performance, odd noises (aside from the gurgling that we hear!).

>>Thermostat stuck

this is what we're hoping (read cheap!)

>>Radiator temp sensor duff

Hmmm...but we are hearing gurgling/boiling therefore I think this one is unlikely!

>>Header tank seal failed

Can you give a bit more detail here....by header tank do you mean were we are topping up the water? Where is the seal?

My Money's on a Duff Thermostat, sounds like its not opening to let the water through to be cooled, its not losing water (i.e. into the oil) its boiling it away! :det:

Cylinder Head Gasket ... overheating, pressurising of water jacket and blowing out vented cap on header tank, water in oil, water being sucked into cylinders and steam on start, not necessarily noisy unless blowing to atmosphere - could be blowing between water jacket and cylinder, performance not always reduced unless very severe.

Thermostat stuck ... best to replace or remove if possible .. OK for fault testing

Rad sensor ... I had this and ended up boiling up in traffic jam on a VX Nova

Header tank... yes reservoir where you put water in, if the seals gone it will blow to atmoshere

Another point ... Picassos are susceptable to radiator header tank leaking - on radiator where the water exits at the top. They are known to fracture / crack

If your water level went low due to loss or the 'not putting cap back on' then you may have air in the system. this needs bleeding out. Send me your email address and I'll forward to you a set of notes that i produced when i replaced my radiator, the top of it had blown, and there are pictures showing where the bleeder are.


My rad blew its top, not in a dramatic way, the coolant level warning came on twice but it wasn't obvious that the rad had gone, UNTIL I lifted up on the top hose to see if it was loose. that sprung the top and water blew out. Without a sealed system, the boiling point of the water is lower which could explan the three bars instead of two on the temp gauge.

Don't just fill up with water either ensure you put in coolant antifreeze and inhibitor.

If the gauge suddenly went up to max and then came down that sounds like an indication problem and not a mechanical one. I think you have created an air lock somehow. I had a similar problem on a ZX a few years ago.

Gauge surging up and down? That's a pretty good indication you've very little water left.

On previous PSA diesels- ZXs, 309s, BXs, etc the gauge sender was stuck on the end of the thermostat housing. It would only read correctly when there was enough water in the system to conduct the heat to it. No water= cool gauge. Unless you actually saw the needle making it's first bid for the red end of the scale you could be driving with a dry cooling system.

Now some of 'em (306s, for example) had a float switch on the header tank, and regardless of the temperature you would know if you were short of water.

Saving a tenner on that floatswitch cost more people head gaskets than I want to think about...

well I did all the obvious checks...but it was dumping water out the header tank when the engine ran awhile. It's now with a local garage that specialises in French cars (run by a french bloke!)....he's just called me to say there's nothing wrong with the head gasket, but the cooling fan isn't kicking in so the water is gettting dumped out the header tank...apparently the front bumper has to come off to get access to the fan - not much else I can do, had to authorise him to get on with it.

Thanks for all your help!

They do if they don't start the fan when the engine gets hot

True. True, Dan

Once had overheating problem with my old Espace. Replaced the sensor only to find both fans had gone! Car'd been running on one fan for ages and I didn't realise until t'other seized up - probably over winter when fans don't get used much, if at all.

What threw me with Shake's problem was the mention of the temp gauge dropping - as if fans were OK.

Glad it's only a sensor, Shake. the bill shouldn't be too horrendous in that case.

Apparently the fan & sensor are both fine...all that's wrong is a bad case of corrosion...but of a bummer that the only access to the fan is to remove the bumper though! It's gonna cost a bit in labour (they've been on while with it - still not finished!)

@shakenvac - what was the outcome? What did the garage find? I’m having similar issues
