Why would a Cuore 1997 stole when it gets up to running temp?

You need to run some tests. When it fails, is it still getting spark to plugs? Is exhaust restricted? Is coolant temp sensor bad?

If the gasket is ok and the surface of the block and head is even and straigh the water is most likely to enter through small cracks in your cylinder head. You should have it tested under pressure.

Check your temp sending unit

A lot of new engines have smaller ports to transport the oil through the engine, and the thicker oils will not circulate well. You can use a 10-w30 and it will be fine. Although the temps are hot there, your engine is still regulated to run at a precise temp, so the outside temp won't contribute to the overall viscosity of the oil. The first number is the viscosity number, so increasing the 5 to 10, you have increased the viscosity value at running temp.

just get your battery changed. Same problem occured in my cuore automatic. thats what i did

Ok....let's start at the beginnning a little bit......have you voltage tested the alternator whilst the car is running.....it should be between 13.8-14.2 v

#1 could be a clogged heater , needing flushed. #2 could be a bad temp switch on the dash. #3 could be a bad warm/cold air door motor which is located under the dash.


Please take a moment to rate my answer............Thanks

Replace Collant temp senser

Have u replaced the MAF sensor?, that is what this sounds like, when they fail they cause a severe loss of power but don't turn on the check engine light, a quick way to test it is to disconnect the sensor and idle the engine for a moment then drive it, if it runs better the sensor is the problem.
