Or sand or part of a camel in this case .. the car is in Egypt!
So I'd guess the system may struggle anyway with the temps they get |
The car used to be fine. I own it since 2000! It never exceeded 85C!

The fan won't kick at high speed when A/C is switched on, only work at low speed. But it kicks with high speed when I unplug the connector from the coolant temp sensor. What could this problem be? Should the fan kick at high speed immediately when you switch on the A/c?
Please advise.

What car is it? Apart from being a 206 we don't know much else. Engine size/type/age/mileage and service history esp timing belts would be useful.
What diagnostic system are you/your garage using to read codes and what are they?

unplugging the sender just puts the ecu in fail-safe mode so runs at high speed as it doesn't know what the water temperature is

It is 1.4 8v old model (1999). I'm the original buyer. The mileage is 200K!

I was trying to check the fan relay to see if it is the problem.

If it runs at high and low speed is probably isn't the relay ...

I finally came up with something. It eats water! But now external leakage. Need to make more diagnoses and run a compression test before judging on gasket or cylinder head.
Has anyone used Block Sealing fluids that repair the blown gaskets and sometimes the worn cylinder heads? Like that one from "Gunk"

Stop jumping to conclusions ... be methodical and check it through slowly and try one thing at a time. If you don't (a) you'll waste your own time and money and (b) we'll stop trying to offer any sensible suggestions to help.
Now you are getting somewhere ... if you are topping it up and it's disappearing we know it is some form of leak. Check the obvious first ... radiator, all hoses, water pump (it might be relatively new but they do fail!), thermostat housing, pressure cap on expansion tank, etc ... if you are using proper coolant and not just water you might be able to see sees of "crusting" ... where the coolant is drying out.
I was losing water in one of my cars with no obvious signs, Turns out the radiator was so badly corroded behind the a/c condenser that it was leaking but in a way that wasn't leaving a puddle or any marks. Tiny holes that the water was blowing out of in almost a vapour.

You can't repair head gaskets that way ... the stuff you put in clogs up everything ... don't use it! And besides you don't actually know what it is yet ...
BTW Is this the only 206 you have?

Gazza82, thank you very much for your comments and follow up. Much appreciated.
I will diagnose it myself today (visually). I suspecting the head gasket or the head cylinder because no signs of external leak, and it consumes water like hill! You fill up the radiater, and drive few kilometers, then all water are gone!
Why don't use head repair stuff?
I used it in one of my friend's Peugeot. It was 307 and was diagnosed as a crack in the cylinder head. The stuff delayed the repair for 60K miles! But didn't solve the compression issue.
Hints:
My radiater is only 3 yrs old (it is Value). My water pump is new, and was replaced 3 months ago (it is the OEM).
Something jumped to my mind that I had a burned fan motor few months ago, and the car was overheated, after I replaced the fan, the car never gone below 95 which is not normal for my car. May be this overheated problem caused a blown gasket or cylinder head issue? It started with small overheat and developed overtime?
From my experience with 206, when a gasket is blow, it never mix oil and water! Which is something I don't understand. I was working for the Peugeot service center here in Egypt in 2003 (as Engineer) and I saw many cars with blown head gasket or worn cylinder head with no oil and water mixed. The water was all the way escaping through the exhaust. I have no idea why, but may be this is something so special in some Peugeot cars?

I can't manage to get the problem solved Nothing seem wrong and the car temp will still rise to 110 degree specially on the highway road.
Fan is working fine on both speed, coolant is fine (it just vaporize due to the overheating problem), water pump is new, thermostat is new, sensors are new, relays are ok!
My last chance is the radiater. Could it be clogged or something? May the radiater flush work or worth a try?

Probably needs replacing by now .. they don't last forever.
are you using a pink/red pre-mixed or mix it yourself blue coolant or plain water? if water only it's likely to be too corroded to be flushed through now. plain water also makes it harder to spot leaks.
red & blue don't mix well either.

I often use green coolant, but have heard it is not good.
Recently, I was lazy, and I used plain water for quite long time. But my radiater is only 3 yrs old!
I have really changed lots of parts and can't solve the problem. I'm afraid that chaging the radiater wouldn't fix the problem.
Parts replaced till now:
-Both temp sensors (brown and green).
-Thermostat.
-Fan resistant.
-The relays were tested ok.
-The water pump is new (was replaced 3 months ago).
-Head gasket is ok.
-Cylinder head was skimmed due to an overheat issue occurred before. It was only 0.25mm skimming.
-Crank sensor was replaced (it was faulty).
-Motor oil was replaced in the regular service.
-Air filter is new.
-New radiater reservoir cap.
Please any suggestions?
I will say it again, car ONLY OVERHEATS on HIGHWAY with a speed EXCEEDS 70KM. It reaches 110 degree. It will overheat also under 70km WHEN the A/C is ON. ECU indicator flashes from time to time, when flashing, the car hesitates a little. I don't know if this is related to my overheats issue.

Sounds like head gasket. Your just burning the water in the cylinder, and
you don't always get oil in coolant bottle.
So if gaskets gone then that makes a leek in coolant system, which stops it doing
it's job properly, that could be why your temp goes up

Thanks wifes206. As I mentioned, my gasket was replaced and the head was skimmed. The car was tested and no problem with the gasket.
