c4 picasso 1.6 thp running hot

[richardwarry]

Hi i have just brought a 2010 1.6 petrol grand picasso it had a few problems that i have fixed but one that im a bit concerned about is it runs hot i have pluged torque in and it rune @ 100-105 c fan will cut in then it goes to 80 but climes up when fan stopes i have only done motorway miles 14 at the moment but it seems ok car light has never come on
so please has any one got a 1.6 picasso they could plug torque and check the running temp over 62 mph as i need to do a 2 hour run on the 10th
many thanks rick

Have you ruled out head gasket ? Sticking thermostat ? It shoud sit on 80 amd as i recall most fans kickin at 92 to 95. Check oil filler cap for signs of gasket failing.

Is the fan running at both speeds?
I think the low speed fan should be running by 95°
Normal operating temperature for these engines is 90°

thanks for replys all normall checks done will change the waterpump just incase headgasket seems ok one fan working going to run it with digibox running to check im getting the right read out but it runs great so not to worried but will get to the bottom of it

had a thought going to replace the waterpump pullys this weekend but also going to check the water tempture manually just incase the new thermostat has a dodgy one as it was fitted by last owner so not sure on quality i will get to the bottom and keep all posted

Are you sure the temperature sensor is giving a correct reading ? Look at values before running the engine, ought to be the outside temperature so possibly about 10°C. The thermostat will start to open likely about 90°C so the top hose should then start to get warm. Fans typically start at low speed at 96°C and then speed up a bit higher. The fan will also run if the air con is working.
