Overheating

[CLANO]

:( I HAVE JUST BOUGHT A ZX (P) REG . IT OVERHEATS AND THE FAN DOES'NT KICK IN. IM HOPELESS WITH CARS SO ANY ADVICE WELCOME

[kfk]

Some advice............Hmmmmmmmm

 

Well how about telling us what engine you have got in it, size , petrol , diesel?

 

have you checked any fuses?

 

has it got coolant in it?

 

Does it only indicate on the display its overheating or has it lost water?

 

If the radiator has a switch on it you might want to dicsconnect the connector and short the 2 wires together......see if the fan works then.....if it does you might need a switch.

Thanks for the info, the car is a 1.9 diesel, it shows up passed 90 degrees on the temp. guage and the fan doesn't cut in. I'll try shorting the wires and see if the fan works then. :(

[This happened to my son's 1.4i. The wires going to the plug which connects to the switch on the rad became disconnected from the terminals in the plug. The switch carries the entire current for the circuit, meaning there are no relays in the circuit to go faulty. If this is the case cut off the premade plug and get two crimp connectors which will fit the two terminals on the switch.

Just noticed the thread is over a year old, so probably the guy alrady replaced the car :blink: but anyways...

Hi,

 

Here is a link with a very detailed explanation of the cooloing system in peugeot 306, which is identical to the ZX.

 

As a first step, I would try to disconnect the Brown connector located on the thermostat flunge, which causes the system to function in "limp home" mode (i.e. both fans work in high spped mode, with no relation to the temp. of the coolant).

 

If they work, I would first check the coolant level (do it when engine is cold, unless you would like to visit the burns department of the closest hospital :o ). also, make sure that the system is bleeded from air. If air is locked in the system, it will badly effect the functionality of the cooling system).

 

If you have sufficient coolant etc. - next step is to check the relays located between the fans (care not to get your fingers caught, else you'll have to visit the hospital again :lol: ), ususaly the relay seats tend to melt or just loose contact. check the exact location in the attached link, where you got a drawing.

 

If all is well, next step is connecting the fan motor directly to battery, and see if they work.
