#1: Running hot Author: Greener89, Location: DurhamPosted: Tue May 07, 2013 4:39 pm ---- The 206 has started to run really hot lately and its getting worrying, its a 2003 1.1 with only 55k miles, its got plenty of coolant in it and its service regular. I do hammer it abit but if I didnt I wouldnt get anywhere lol! Anyone else's 1.1 run hot? Sits at 90 degree when driving normal, heats up dead quick from being cold, soon as I sit in traffic or stop for say 2 minutes the fan comes on. if i hammer it abit its temperature rises to temp just before the fan kicks in. It never used to run like this. Could the head gasket be on the way out does anyone know? If so am getting rid. Put it this way the fan has been on that much lately its packed up and no longer spins and just makes a massive noise! New one is needed asap. Thanks for any advice
#2: Re: Running hot Author: DREWDEN, Location: huddersfieldPosted: Tue May 07, 2013 5:18 pm ---- Could be an airlock in the cooling system, worth checking.
#3: Re: Running hot Author: kandlbarrett, Location: SwindonPosted: Wed May 08, 2013 5:00 pm ---- Possibilities:-
Air lock.
Radiator matrix is failing internally (blocked.)
Your thermostat is sticking.
Blocked air flow through radiator. (Anything like a rag or even dead bird etc. got in there blocking it.)
Radiator hose weak and collapsing reducing flow.
Water pump failed.
Headgasket.
You must get a replacement fan quickly. If your head gasket isn't already failing without a fan and with your problems you describe you are soon going to have a failed gasket.
#4: Re: Running hot Author: Sotirios, Posted: Fri May 10, 2013 6:55 am ---- I think that I have a similar problem with my 206 1.6 (2002 model). Since last week, the cooland temperature starting warming up normally up to 90 degrees but it doesn't stop there. It continues to rise unless I put it to idle and put the heating on in the cabin.
Today I checked it parked, so it was on idle: At 100 I could hear the low speed fan turning on but it continued to rise up to 110 degrees (2nd line after 90) where the High speed fan started. I didn't turn the cabin's heating on to see what would happen and it started rising even more where I decided to turn the engine off to prevent it from going to red.
Any suggestions anyone please?
I am not very much into car engines...
#5: Re: Running hot Author: V9977, Location: Athens, GreecePosted: Sat May 11, 2013 7:06 am ---- Sounds like coolant circuit / radiator would need to be flushed as a first step and take it from there.
Also, very often the heater matrix in the cabin is blocked preventing proper flow of coolant, irrespectively of heating setting.
Wax thermostat is 89 deg. C on the 206, that could be getting stuck too.
Proper refil and bleeding takes some care and effort ime.
Sotiri where are you from?
#6: Re: Running hot Author: Sotirios, Posted: Sun May 12, 2013 10:36 am ---- Thanks V9977.
I am from Athens, too but I live in UK now.
Your number plates are from Ioannina?
What do you mean by the heater matrix in the cabin? And is there something that I can do about it?
I will probably do the flushing bit first.
I would like to avoid getting to a garage.
Is the wax thermostat the sensor located at the engine's exit toward the radiator?
Thanks again for the help.
#7: Re: Running hot Author: Sotirios, Posted: Mon May 20, 2013 5:57 am ---- I drained the coolant yesterday. I did that by opening the top and bottom hoses at the radiator.
Then I flushed it with clean water. I inserted water from the coolant reservoir and from the top hose at the radiator until it came out clean.
Then I fastened the hoses back and filled new coolant at the reservoir.
Run the engine for a while and added some more coolant.
Today it was a bit better at the beginning but then it started to raise the coolant temperature again.
This time the top hose at the radiator was not hot at all.
Did I do something wrong?
#8: Re: Running hot Author: MrBSI, Location: What's it to you? ? ?Posted: Mon May 20, 2013 5:58 am ---- Did you bleed all the air out of the cooling system?
#9: Re: Running hot Author: Sotirios, Posted: Mon May 20, 2013 8:19 am ---- No I didn't. Is there a way now that I can do that?
#10: Re: Running hot Author: V9977, Location: Athens, GreecePosted: Mon May 20, 2013 8:37 am ----

There are two points which you undo to let the air out.
One is on the side where the top radiator hose connects to the engine coolant housing (allen screw). The other is on the top hose which goes to the cabin heater at the back wall of the engine bay.
Let the car idling get up to temperature until the radiator fan switches-on,
then undo each bleed point in-turn until water comes out with no air and no air-bubbles. You will have to add collant probably if a lot of air comes out. Also squeeze the top hose going into the radiator every so often to get any air moving.

Ioannina was the previous car owner and first registration.

I can see a visit to A and E on the horizon.

That's how I do it anyway.
#13: Re: Running hot Author: Sotirios, Posted: Mon May 20, 2013 9:30 am ---- Thank you all.
I will try it and then come back.
#14: Re: Running hot Author: Sotirios, Posted: Tue May 21, 2013 4:57 am ---- Hi again.
I tried to take the air out yesterday but I don't think I did it right.
I let it warm up in idle and then I unscrewed the allen screw. There were 2 screws there (one at 12 o'clock and one at six). I only loosened the top one and moved the hose sideways to let coolant split out. I couldn't tell if it was only coolant or if there was air coming out of it, though.
Then I tightened that screw and loosened the other bleed point at the back of the engine towards the cabin.
Again, lots of coolant went out with pressure and I couldn't tell if there was any air either...
I also squeezed the top hose several times but I don't think that made any difference. In the end it still remained cool while the bottom one was hot.
I must be doing something wrong!
#15: Re: Running hot Author: V9977, Location: Athens, GreecePosted: Tue May 21, 2013 7:17 am ---- Did you have the car parked on level ground?
Was the expansion bottle cap removed?
Was the heating in the cabin set to max hot?
Did ypu let it warm up until the radiator fan switched-on at the front?
Be careful you don't burn yourself as Macca said.
#16: Re: Running hot Author: Sotirios, Posted: Tue May 21, 2013 7:30 am ---- Car parked on level ground: Yes.
Expansion bottle cap removed: is that the coolant reservoir bottle? I had it shut.
Heating to the cabin: Setting in hot but the fan was shut.
I let it warm until the radiator fan whiched on.

Needs to be open.
You have to squeeze the top pipe and see for possible bubles in the reservoir.
Let the bleed points open for quite a while and careful you don't burn yourself.
#18: Re: Running hot Author: eddie206, Posted: Tue May 21, 2013 7:53 am ---- Just to make sure people know they need coolant/antifreeze in there cooling systems...its not just antifreeze to stop freezing but it also helps to keep the system cool.
Its vital to have a good correct amount of coolant/antifreeze in the car as water alone will not cut the muuusttaard...say i.
#19: Re: Running hot Author: Sotirios, Posted: Mon Jun 10, 2013 4:22 pm ---- Hi all, it's me again.
I did everything mentioned above.
Some air (bubbles) came out from the allen bleed point. Nothing from the rear one (I managed to lose the tap, which I successfully replaced with a tap from my bicycle!).
But, apart from a slight improvement, the problem is still there.
I am able to keep the coolant temperature between 90 and 100 using the cabin heater on maximoum setting.
Any other ideas?
#20: Re: Running hot Author: V9977, Location: Athens, GreecePosted: Mon Jun 10, 2013 5:58 pm ---- Γειά σου Σωτήρη,
It could be thermostat stuck closed, still clogged collant system/radiator or loose waterpump fins..
Sounds like it would need to be looked-at at this stage if you are still not happy with the engine temps.
#21: Re: Running hot Author: Sotirios, Posted: Tue Jun 11, 2013 9:11 am ---- Hi all.
I did everything that was mentioned before.
There was some air (bubbles)coming out from the allen bleed point.
No air came from the back bleeding point. I did manage to lose the cap, which successfully replaced by one from my bike!
There has only been a slight improvement but the problem is still there.
I can keep the coolant's temperature between 90 and 100+ most of the times by setting the cabin's temperature to max hot.
Any ideas?
