Please clarify what you mean by "crank up". Do you mean that the engine won't crank when it's cold? If that's the case it might be a battery problem. Sometimes a battery can produce enough current when it's warmer but the temperature drops, the chemical reaction will slow enough that it doesn't make enough current to crank the engine. Have the battery checked. When a battery gets to that point it is weak enough that it will show up on a routine test.
IF YOUR CAR LEAKS WATER AND HEAT BLOWS COLD AIR WHAT THE PROBLEM
I need to know why do i need to crank my chevy truck to start ?
If you live in a cold climate the more the better.
could be bad bushings in the starter.
You will have only cold air coming thru your heater ducts if your core is defective.
Your cooling system is empty of coolant and you must have a large leak somewhere.
I have a 1997 Chevy Malibu with 176k on it. Never had a new engine or anything, runs like a champ. It has been making a knocking noise when its cold.(until car is warm) for a long time now. It still makes a little one while at idle, not loud or can even really be heard though.
Low coolant, stuck thermostat, blocked hoses.
Stalling at idle? Immediately after starting? While driving? While stopping? Cold or hot engine? What engine do you have?
