Bought a 10 year old BMW Z3, it was okay the first two days then yesterday it started to over heat, smoke?

Question

coming out of the front grill and cutting out, filled it up with water and oil, then it worked for a bit, this morning after sitting all night with water in it i drove okay for about 45mins then the needle went in to the red over heating again, any suggestions to what it is? And costings?

Answer 1

Don't even bother trying to find out. Take it back !

Answer 2

I would try to take it back (go with some well built friends), it looks like they sold you a pup and that's not nice.

Sorry but there are many questions to clarify.

Is it smoke or steam?

Is it coming from a pipe or hose or a hole in the radiator?

How much oil was needed? does it now need more?

You may need to check thermostat as other suggest, then radiator then water pump and head gasket and bank balance

Answer 3

Sounds like a thermostat - if thats the problem, your in luck they are fairly cheap and easy to replace.

Also could the fans not be working?

You should hear them running.

lastly check that the hoses are not flattening out when it is started.

Answer 4

first thing id replace would be the thermostat .. if it over heats fast good bet that  is the problem as for cost about 20 buck if you do it... for a shop price call any shop

Answer 5

you got a lousy azz car
