#5: Re: losing coolant Author: DREWDEN, Location: huddersfieldPosted: Tue Nov 12, 2013 5:45 am ---- The temperature will be reading low, because the coolant is not reaching high enough to monitor the temperature sensor which is a green plug down and to the right middle of the engine cover, on the engine block.
When the engine is cold top the level up and start the car and see if its leaking around the plug, or anywhere else in the cooling system.

Have you tried (carefully) getting it up to temp with the cap off?? Make sure its not bubbling too much (headgasket coolant/bore leak)...
Any spots on the driveway/road?

#8: Re: losing coolant Author: moonbutter73, Posted: Fri Nov 15, 2013 3:07 am ---- always overfill the coolant tank, as u cant see the level thro the thick plastic
#9: Re: losing coolant Author: DREWDEN, Location: huddersfieldPosted: Fri Nov 15, 2013 8:21 am ---- You shouldn't keep filling water till it overfills, as in the expansion tank there should always be an air gap between the max mark and the filler cap, this allows for a space when the coolant expands when it is hot.
Read on here somewhere if you shine a torch at night, it should show you where the level is, make sure the engine is cold when doing it for correct reading.
