Sold my car to my cousin yesterday... and this morning she goes to do the school run, and it starts to overheat (light stayed on the whole time flickering) so told her to top up the water cos it could be low.
Problem is it did the same when i got it, we thought it was headgasket but it turned out to be thermostat.
Since then (4 weeks) its been run all over, and havn't had a problem, until today of course, even spent some money on it to get it sorted.
I took out the thermostat, i drove it for ages and seemed all ok. Then on the way home i get a call saying its done it again.
What to do, its driving me nuts. could it be the waterpump or worse the headgasket.
HELP PLEASE
