Wont start when cold

-Thermostat is not control the heater. It control only temperature in the engine.
-If you have no heater then check the following:
Make sure engine is cold before perform check.
-Check radiator is full of water or not. If not then fill it up
and try run like normal and turn on the heater.
-If now you have heat then you're done.
-But still no heat yet then cheek:
The heater valve. Is it open properly when you switch to hot or cold? If yes then NOT THE VALVE. Next lose both heater hoses from the engine and flush with garden water hose from one end and the other until you see water come out either end. Now connect back to the engine and top of the radiator more water.
You should be good to go now.

Good luck and stay warm

LET YOUR CAR WARM UP FIRST!! or you risk the chance of over heating and casuing engine damage. start your car let it warm up for 5 to ten minutes and then try the heat. also when you start you should NEVER have heat on right away. the heat that you feel comes from the engine. and if the engine is cold and you are trying to heat it up it will put stress on the engine and over heat. ALL cars have to wait for their heat. that's why you see peoples car running in the morning with no one in it. so when they do get in it they have heat. heat will not work until the engine is warm.

Probably have water in the tank

disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec

check radiator fluid is full the heater operates buy the radiator fluid flowing through the heater core. next your thermostat might be stuck in the open position thus your radiator fluid not heating up on cold days - no hot radiator fluid no heat. if fan is not coming on check fuse first if fuse is good check heater fan motor

Choke isn't suppose to turn off until engine is warm. When was last healthy tune up? Replace plugs, wires, ALL filters especially FUEL filter and run a good fuel system cleaner through it w/next tank full of fuel

Because it is a diesel engine. They use compression to push the air and fuel mixture together. It pushes them together under such high pressure that they heat up enough to spontaneously ignite. If the block is cold, the mixture won't get hot enough to ignite. If you don't have a block heater, you need to have one installed so that it'll start when cold. Your only other hope of getting it started, besides building a garage to keep it in, is to put a tarp over the hood and run a propane or kerosene heater under the engine until it is warm enough to start.

the heater is not designed to heat wter from cpold to hot. it is only designed to maintain the hot waterb temperature. your problemis that the initial water going in is probably cold. you have to run faucet until it gets hot then start the machine.

Generally speaking, dishwashers don't heat cold water on their own. Be sure the dishwasher is connected to a hot water supply and that hot water is available to the dishwasher at the START of the cycle.

Often it takes hot water several seconds for house plumbing to deliver hot water to an outlet. If the dishwasher is connected to the kitchen hot water supply, run the water in the sink until the water runs hot before you start the dishwasher.

Dishwashers often have heaters to heat the water even hotter than most home water heaters, but they are not intended to heat cool or cold water. You MUST furnish hot water to the dishwasher from the time the cycle is started.

I've seen houses that take so long for hot water to reach a faucet, the dishwasher is already full (of cold water) before the first drop of hot water reaches it.

Good luck. Hope this helps.

change the thermatstat it has aweak spring in it .could fail all together and over heat
