I need a car expert...can you help me?

Your problems are probably not related. The overheating could be a trapped air bubble behind the thermostat, a bad thermostat, a blown head gasket or a fan not coming on. You start by feeling the radiator hoses to see if you have circulation when the gage is in the middle. If both upper and lower hoses ar hot, you have circulation. The fan should click on shortly after you have circulation. If it does, but still overheats, it's probably a head gasket. No circulation= air bubble or bad thermostat or clogged radiator. I don't think you are qualified to fix it, because you need a pressure tester to force the air bubble through the thermostat (if that's the problem). If you or someone removed the thermostat, that can cause a hose to collapse at higher RPMs causing overheating, also. If the head gasket is blown, it takes someone who knows how to replace and fix the necessary parts. Lights not turning off; the lights are designed to stay on even if the key is off. It is probably a bad switch.

Scrap the car you will get around £200 for it and put the money to another one,

ok louis get a new battery generator or alternator for your car also it might be a wiring problem short circuiting in the car this may be causing this the overheating is because of the wiring or coolant your using

I could tell you how to be frugal like me.

How to save the money you have: Stay away from cigarettes & drugs! use cantines instead of buying waterbottles or sodas, get water instead of sodas at the movies & restaurants, try to eat at buffets instead of restaraunts, shop for clothes & furniture at discount stores, use spiral bulbs instead of normal bulbs, watch movies on putlocker or youtube instead of buying or renting them, when you buy a car buy a small efficient one instead of a truck or SUV, & if you ever build your own house order white roofing instead of the usual dark. Another somewhat frugal habit is using progressive grammar like me (&>and, 2>two, 1st>first, %>percent) when you're writing papers. If books used progressive grammar they'd be shorter & cheaper to make.

How to make some money: Collect cans & other scrap metals & take it up to your local metal recycling place that pays you. If you have any books or DVDs you don't want anymore sell them to Half Priced Books. If you have any unwanted gold or silver sell it to Cash4gold. When you pass by vending machines look in the coin slots for coins. In my experience 1/10 of them have coins.

If you're a kid & some of this doesn't apply to you, saving on electricity still saves your parents money. If you wanna be radical then follow power4patriots & make your house energy independent.

With that money, it would be best to spend it on stuff that will improve your life & stuff that will last such as spiral bulbs, new leather furniture, or emergency supplies. This world would be a much better place if everybody was frugal & I hope I am making this world better by answering questions like this. If you don't wanna pick me as best answer at least let me know if my advice has helped you & if you wanna become frugal too. It's up to us to make our future better by spreading frugality.
