Top Up Engine Coolant Level

[oxtobyd]

Ok, working through little problems with the C5 i picked up the other day (managed to fix a wobbly seat with a bit of drilling and new nuts/bolts) anyway. When i turn ignition on i see the message "Top Up Engine Coolant Level" but this soon goes, and temperature gauge sits at around 1/3 to 1/2 during runs.

 

i've checked the coolant level (under the bonnet, left hand side, near the back) and it all looks fine, was surprised how pressurised it was though (lots of hissing noise when taking cap off)

 

is this a normal message, any hints on fixes?

 

cheers

I would check the sensor for the coolant level is ok first.

 

Pressurised expansion tank? Some pressure is normal, as the cooling system runs under pressure but excessive pressure is possibly a dying head gasket. Start up the engine from stone cold and see if there are bubbles in the expansion tank with the cap off.

 

Otherwise consider bleeding the system.

 

Have a look at:

 

Another Water leak

cheers for that, is the sensor something i can check for myself? and where would i locate it?

 

i'll check for bubbles when it stops pouring it down with rain :-)

 

cheers

 

edit: now its stopped raining, checked for bubbles and none... phew! also logged into the citreon service site and found which is the level sensor and i'm going to rule that out for now since i've just added a bit more coolant (even though to me it looks pretty full) but thought i'd add a bit more and i'll see how we go.

hi andy its http://service.citroen.com/ where i created an account and it lets me see the parts list and exploded diagrams with part numbers etc, so pretty good for the basic, and it looks like you can also get access to technical docs if you pay a small fee.

 

hope it helps
