Coolant Change And 12v Power Socket

[Guest huven58]

Hi.

 

I have a 2007 Citroen C3 1600 (auto trans.).

 

1) Tech people will be angry with me about that, I asked your forgiveness from ahead :) , I forget to check the coolant for a while and when i did the transparent coolant tank was empty (way below MINIMUM). I filled it up and after a day the whole tank became brown (probably dirt or corrosion), now I want to change the entire coolant but i have a problem, in my old car (Mazda) there used to be a opening on top of the fan to refill it after i drain it and now i cant find it.. someone can please give few points how to drain the entire coolant to clean the system.

 

2) My 12V socket isn't working for a while, I have only one fuse under the steering wheel and its the drivers windows fuse, BTW its use to work and no fuse's was taken out. Any ideas ?

 

Thanks.

 

PS

my English is a little lame.

Welcome to the forum.

1. The coolant level in the expansion tank should not go down so I suspect you may have a leak somewhere which needs to be checked. Leak possibilities can include the expansion tank cap not fastened, the bleed screws not sealing (located at the right side of the engine cylinder head and also on a heater hose at the bulkhead), water pump seal leaking, radiator leaking, hose leak, cylinder head gasket failure, overheating and the water boiling out of the expansion tank cap.

 

Following is based on the Haynes manual for the petrol engines. To drain the coolant, you need to remove the bottom hose from the radiator. Also opening the 2 bleed screws will help. Refill the system through the expansion tank, open the 2 bleed screws to let out air and close them when coolant starts to run out. When filling, to get all the air out, the coolant level in the expansion tank needs to be the system highest point - Haynes allows a higher level by inserting the top half of a 1 litre bottle in to the expansion tank with a seal whereas Citroen use a header tank.

 

2. The fuse for the 12 volt socket should be in the fuse box below the steering wheel (LHD car). Check in the car handbook but it may be fuse 22 and of 30 amp rating. The fuse box may need to be pulled down to access but I have never done this before.
