Overheated. Why won't it start?


I'm not really familiar with JEEP mechanics but if you've replaced your water pump and it's still overheating with full water/coolant level, you should check the thermostat; when it fails, it's a common cause or overheating in all kind of cars

I'm attaching some links to Youtube tutorial about replacing thermostat in a Jeep but you can expand your Google search using terms

Water leaks from top of coolant bottle


You may be overheating. The water pums have been an issue with these cars (Audi,VW). The impeller breaks and will no longer push water. This can be verified if you remove the thermostat and turn the impeller with your fingers (vehicle off of course). If you're able to turn it replace water pump, thermostat and timing belt.

My xtype 3.0 is overheating I already change thermostat hoses radiator water pum put antifreeze ac fan and still overheating what about air in the system?


You may have a blown head gasket. 1st check to see if your coolant level is good, if it isnt make sure you top it off, run it for 20 minutes watching the temp. and putting the heater control to full hot to be sure you bleed out all the air that may be in the system, after 20 min or when the temp rises too hight turn it off, let it cool, open and top off as needed, repeat after topping off, do this till it no longer takes any more coolant and is no longer overheating. If your still overheating and slowly losing coolant you more than likely have a blown head gasket, they have a sniffer test you can do at the radiator cap your local parts store carries them or your local mechanic can run the test.

1997 Grand Am overheated. Fan, temperature gauge changed. Head gasket replaced. Car was running fine, couple days later, acted like it wanted to overheat, why does it keep doing this?


I think you need to clean your radiator(open water tank and remove all dirt inside it and inter in water hols and pipe thin stick), change thermostat to lower degree heat, if the problem continue try to remove thermostat.

MY CONTOUR IS OVER HEATING


Most people think of this is a common problem of the thermostat. To make sure it is not the only problem, run your car a day or two without the thermostat to make sure it is not overheating anymore, then put in a new thermostat. Your problem is solved.
However, if your engine still has overheat without the thermostat, then there is a problem with restriction of coolant circulation through the engine from 3 followings:
1- Radiator clogged up.
2- Water pump is bad.
3- Water jacket is clogged up.
A shop can easily determine if the water pum bad or not.
Make sure to find a reputation shop since a yo-yo shop can change your water pump first then later on determine the clogged up radiator is the culprit while you are not actually needing a water pump at the first place. Why, a good water pump still causes overheat since the radiator is clogging up. My advise is not to use a rebuilt radiator, go with a brand new one. It can last you 10 years instead of 2 years on the rebuilt one. Good luck.

My car is overheating. I just replaced thermostat and recently replaced the water pump. I checked for water leaking but dont see any. What could it possibly be


If the thermostat and pump have been replaced, it's most likely the radiator. They corrode after time. Try flushing the antifreeze (not just draining and refilling it, but flush the system with clear water.) Most auto stores, Walmart, etc. carry the flush kit for very little $$. Once it's flushed, refill the system with the correct ratio of antifreeze.

If the problem persists, then it's most likely gunk in the radiator. Auto shops can boil them clean.

Short of all of the above, overheating can also be caused by a cracked cylinder head. If it overheated too bad at any point, it can crack the head and will continue to overheat regularly. Check for antifreeze in the oil. If there "is" antifreeze or water in the oil, the head is most likely shot (and yes, it will still run that way).
