Let's start with the obvious make sure the radiator has antifreez second check for cracks in the radiator cap rubber this also overheats an engine then make sure that once the engine gets hot the radiator fans go on if they dont it will overheat if both are ok then you have to make sure the thermostat is not the problem it could be stuck closed change it also check the water temperature sensor it might be faulty or the wires might be coroded.The temp sensor is cheap so buy a new one it's about $10.00 the other thing is a water pump failure or a radiator or heater core calcium build up clogging up the system brought on by using water instead of antifreez or worst case scenerio a blown head gasket check for water in the oil or water coming out the muffler accompanied by a white cloud of smoke you could also check the spark plugs for antifreez on them this would indicate a head gasket problem

Cold starting Ford F 150 below 30 F will click solonoid have to wait to start


Sounds like the solenoid for the starter has a burnt spot on it. I don't think leaving the key on is heating up the starter so I do not know what is happening there. Are you getting a lot of water up in the starter so it is freezing over night. I would test the solenoid or replace it.

1995 ford 4.9 stright 6 runs for a couple min then dies


The parts you replaced don't typically fail due to heat/cold cycles.You need to see if it might be the ignition coil.Make the coil easily accessable(take of the engine cover).Have a 12v test light and some sort of spark tester handy.Start the engine,let it run until it quits.See if you have spark at the coil.If not, unplug the low voltage connector on the coil,and put the test light across the connector,and crank the engine.The light should flash on and off.If it does,replace the ignition coil. If it doesn't flash,you may have a bad crank sensor,but this usually won't make it shut off,instead,it will cause it not to restart after heat soaking for a couple minutes.(I'm betting on the igniton coil).

My 2009 mini cooper shows a yellow car on what looks like a hoist and when I check the problem on the computer it says battery drain. Also my clock stops running. It has been very cold here minus 25...


It probably just needs charging. Cold weather can take a toll on older batteries, especially when they are left sitting for long periods of time. Starting the engine every day is ok, but the short run time isn't replacing the energy it took to start it.

A few Problems: Starting, Heater & Radio


Problem 1: buy a system heater to keep the engine warm at night.
You can buy them at any autoparts store . You take your pick from the variety.
Place a light 100 Watt Bulb near the battery but not too close to anything else where it might burn anything.

Problem 2. Check your coolant level to see if you have the proper level. Make sure you have 1/2 antifreeze and 1/2 water if you add any coolant /antifreeze and bleed the colant system. By running the car let it cool, then turn the radiator cap or turn the bleed screw provided on some cars near the thermostat outlet. Then adding some more water and coolant etc.The tightening the cap or bleed screw. When radiator is full. Check the radiator and and remove any debris that may be keeping the air out.

Problem 3. Will get fixed because your battery won't die.
