Well, I have changed the starter, alternator and battery. It will go for awhile then it will shut off and then the engine says low coolant. I then turn it off and it wont start. What is the problem.

Hi,

Do you actually have low coolant? If this is the only warning light and then the engine will shut off and not restart, it may be overheating or at least think it is overheating.

Does you temp gauge stay steady and not showing it overheating?

If so, we could just have an issue with the coolant level sensor if the coolant is not low. Sometimes these vehicles will see the coolant low and the PCM will shut the engine off so that it is not damaged. However, this normally only happens when the addition of it actually starting to overheat.

I would suggest with starting with checking your coolant level and if it is low, top it off. Also, scan for codes. If you do not have a code reader, just stop by a parts store and pick up some coolant if you don't have any and ask them to scan for codes. They should do this for free if it is a larger chain type parts store.

Let me know the coolant level and then if there are any codes and we can go from there. Thanks

Now they say it's the motor. If turned over and there is a click when you turn it over. Does that mean it needs a motor?

It could but that is not much information to go on so if that is all they gave you, maybe going down and having them show you what the issue is will help. If you can get a video of the issue you are describing.

It is not common for a shop to just recommend an engine with out significant proof so I am sure they have a reason. If they are correct, then they need to help make you feel comfortable with that recommendation and they do that by showing you why they say it needs an engine.

If you don't feel comfortable with it, then don't do it. When people trust a shop that they don't know they can trust because they have no history with them, they end up being dissatisfied. It is good for all parties if you understand what the issue is and why they are saying an engine will fix it. If they can't do that, then maybe a second opinion is warranted.

Let me know what they say and if you can get a video of it and we can go from there. Thanks
