My 05 Chrysler300 5.7 hemi ran hot because my belt was loose and cranks but won’t start
My car got hit and it knocked my belt lose so it ran hot the next day when i was goin to work. It was driving perfect so i cut it off for a while. I cranked it a couple minutes later and it cranked. Then i tried it again and it only cranks but wont start and it keeps draining the battery so everytime i try now ill have to charge the battery
Experienced mechanics share their insights in answering this question :
If your belt isn’t tight like it should be, your alternator probably isn’t charging your battery properly. If it continues after you replace your belt, you may want to look into replacing your alternator. If your belt isn’t tight even without driving, you may want to replace your tensioner pulley.
Your belt not being tight could possibly be the cause of the problems that are occurring. The first thing you will want to replace is the tensioner pulley and possibly the belt if there is any damage done. I recommend having a service technician, such as one from YourMechanic, replace the tensioner pulley and perform an inspection to find out if your alternator is performing the way it should.

However, your timing belt helps power the water pump, oil pump, and injection pump. If any or all of those are not operating fully, it can cause your engine to overheat. This also risks more damage to other parts, as heat can be hard on the metal parts of your engine.
The most common reasons a Chrysler 300 is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat. Coolant leak (water pump, radiator, hose etc.)
engine overheating: although rare, if the water pump is driven off the timing chain, a loose timing chain may result in engine overheating.
The most common reasons a Chrysler 300 won`t start are a dead battery, an alternator problem, or failed starter.
The serpentine belt is a single, continuous belt that drives multiple devices in your engine, such as the alternator, power steering pump, water pump, and air conditioning compressor. If your serpentine belt breaks, all of these systems will shut down and your vehicle will overheat.
If your serpentine belt is failing, you may notice performance issues with your vehicle. The vehicle may frequently overheat. Your air conditioning or power steering may fail to work or not work properly.
What Happens When The Timing Belt Is Too Loose. If the timing belt is too loose, your engine may not run as smoothly as it should. A loose timing belt allows the crankshaft and camshaft to be less than perfectly in sync with each other. The engine will still run, but not as smoothly.
Alternatively, your timing belt can “jump a tooth” causing your vehicle to suffer from loss of power. You will notice rough running conditions; including, odd idling and flashing check engine light.
If the belt is worn or loose, it will slip and cause cylinders to open and close earlier than they should. If this timing is off, the engine will run erratically, if it runs at all. Engine misfiring is a sign of trouble that should be checked as soon as possible to avoid risking serious engine damage.
This damage interferes with the rotation of the belt causing torn belts, or the belt falling off of the engine. Without a belt, stalling and overheating of the engine become commonplace.
A broken serpentine belt may stop the water pump from circulating coolant through the cooling system, causing the engine can overheat.
All that happens when the belt disappears or pulleys seize is the alternator stops turning; there is NO possibility of damage to the alternator. Once you re-apply a new belt, or new pulleys, the accessories start turning again, just like before and the alternator produces current to charge the batteries.
Repeated overheating can be a sign of serious engine damage. Repeated use of an overheated engine can accelerate that damage rapidly. In extreme heat, core parts of the vehicle`s engine can crack, warp, and fail — resulting in instant death to your vehicle`s powerplant.
Technically speaking yes you can use plain water in your cooling system but it isn`t recommended as a long term solution and certainly not in extreme weather conditions.
Engine Overheating
If your vehicle`s engine overheats, it could be due to failing spark plugs. Overheating can happen for a number of reasons that can cause your engine to be too hot. This can harm your engine parts and lead to expensive repairs down the line.
Knocking Sounds
If the timing belt tensioner is loose and the timing belt is getting stretched out because of this reason, you will continuously hear knocking or slapping noises. This happens because the loose timing belt hits several parts inside the timing belt cover.
When the belt breaks, the valve springs will slam all the valves closed. From sheer inertia – no matter how fast you were going or even idling – the crankshaft will continue to move the pistons up and down for a short time and will hit the valves.
Under normal conditions, the smaller diameter sheave of a given drive will wear faster because it makes much more contact with the V-belt. Efficiency losses of 5% or more can be expected when a wear gap of 1/32” is present.
The timing chain does not have anything to do with the cooling system and would not have caused a coolant leak. Your car has a warning indicator that lights up in the dash when it is low on coolant or oil telling the driver to shut the engine off, but it will NOT shut off on it`s own.
It can also be seen that advancing the timing increases the peak temperature (see Fig. 16.18) achieved during combustion, but tends to decrease the release temperature, while retarding reduces the peak temperature but increases the release temperature.
The Pirelli tires used on Euro-market cars allow a top speed of 155 mph versus the speed-governed 126 mph for U.S.-market 300C Hemis. Curb weight ranges from 3721 pounds for the base 300 to 4046 pounds for the 300C.

It seems like just yesterday, but the Chrysler 300 has been around since the 2005 model year. While some vehicles have used different batteries over the course of their production run, the Chrysler 300 has remained constant, using an H7, for which OPTIMA batteries offers a direct-fit replacement DH7 YELLOWTOP.

The car crank but won’t start
ANSWER : Hi there. This does sound like an issue with the wiring. If the check engine light is coming on every now and then this means that when it does not come on there is no power to the computer. This can be the wiring harness issue or an ignition switch problem. I would have to test for voltage to the computer when the problem is occurring to be able to find where the issue lies. If you need assistance, a certified YourMechanic technician can be dispatched to your location to inspect your vehicle’s non-start issue and suggest any necessary repairs.
72 Chevelle cranks but won’t start and has to be flooded but smell no gas
ANSWER : Gasoline is generally not usable after 3 to 6 months. If gasoline has been stored in the vehicle for a lengthy time, the problem is likely that there is just simply nothing to combust. The volatile components in the gas have evaporated and other compounds in the gas have turned to varnish and gum, possibly plugging up the carburetor. If the tank was drained though and the fuel in the fuel system is fresh, please simply request a no start diagnostic and the responding certified mechanic will pinpoint the cause of the no start condition. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
The car is having trouble starting up ,70 percent of the time it starts right up. the other 30 percent, it randomly won’t start its
ANSWER : Hey there thanks for writing in about your 1998 Honda Accord. This could be a few things. A faulty ignition switch, a failing crank sensor, or possibly other faulty sensors could be the cause. To have this taken care of, consider having a certified technician, such as one from YourMechanic, come to your car’s location to diagnose and repair the hard start issue.
Vehicle won’t start, once it’s jump started it only stays running until you turn it off, then it work start again without jumping.
ANSWER : Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery. The second problem could be that your alternator is bad and not charging your battery, in this case you will need to replace your alternator. Both the battery and the alternator can be tested in your car. If you would like to have the car checked for you, a certified professional from YourMechanic can come to your car’s location to diagnose the starting problem and proceed with repairs.
my 2003 saturn ion won’t start. it cranks but won’t start.
ANSWER : Hi there:
If you checked the oil and determined that there was no oil in the car, it’s quite possible that some internal engine components have seized up; which means there might be serious engine damage internally. Before you attempt to crank it again, please contact a professional mobile mechanic to complete a car is hard to start inspection; so they can pinpoint what is the source of your issues before it causes more damage.
When I try to start it, it cranks slowly as in cranks like dead battery but then cranks just fine but won’t start
ANSWER : Hello, and thank you for writing in. To begin there may be issues with the wiring, position of the starter, a faulty starter, or an issue with the timing. However start with the simplest options and work you way up in complication. With replacement starters, it is often required to add a shim to the mount in order to align the starter correctly. If the gears are misaligned, or not making good contact, then the starter motor will bind or move slower. This may even result in a grinding. Secondly with a voltmeter you can test the voltage available to the starter and see if it is receiving the full 12 volts. If it is not, then you may have a bad wire, a loose connection, a dirty connection, an issue with the starting system, or a bad ground. If it is, then you want to look deeper into the alignment of the starter, and check if it was a re-manufactured replacement part. After you rule out a faulty starter you can then resort to the timing and other sensors. For more diagnostic help, contact our service department to schedule an appointment.
So I have a hyundai sonata se push to start. My car won’t turn on, power is working, I push tof start but it won’t crank. I don’t
ANSWER : Hi there. It sounds like you have a failed starter. However, without proper testing there is no way to be 100% sure. I suggest having the battery tested first with a digital battery tester that provides current voltage, cold cranking amps, and state of health. Also inspect for corrosion on the terminals and cables as this will cause excessive resistance and not allow proper voltage/amps to the starter. Other possible failures could be in the wiring harness, relay, fuses, or communication network. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car does not start inspection.
