I'm new to this site and new to landrovers, I bourt a defender 90 2.5 td 1989 model 6 months ago now since iv owned this caro have had a new starter motor a new thermostat a new exhaust a newclutch and she requires a new master cylinder for clutch, also I have failed 2 MoTs on numerous things including welding in 6 places leaking steering rack and loads of little things bit to my advantage I'm a welder so iv done it all and all the bits that needed doing and she passed this week, now I got 2 problems? 1 she seems to overheat after driving for 20 minutes or so the needle sits between half way and the red! Is this normal? I have as u say changed the thermostat and flushed all water from radiator and Put fresh in but she stays the same, also today I have yet another problem! Every time I turn (eitherway) at around 25mph upwards I am getting bad vibration and a sort of grinding nOise coming from the front end somewhere and since this has started I have noticed that when I brake there's nocking feeling coming through the peddal like a nock on every rotaion of the wheel or sommet, can any 1 help I'm new to defenders and I'm no macanic but I will give it a go like all other work I have done myself.
