Can a bad tensioner cause an engine to overheat?


A bad tensioner can cause an engine to overheat in the sense that when a bad tensioner breaks, it will cause a loss of turning movement to all the accessories of the engine including the water pump, and when the water pump stops turning, the flow of coolant will stop and the engine will start to overheat.

2000 sebring 2.5 stalls out and overheats


Have the fault codes read. Replace faulty items. Use only genuine items as non-genuine replacement are not always compatible with the OEM fitted CPU units. The engine light is telling you that the cpu has found a fault ( probably overheating) from a radiator fan not coming on. The stalling could be the cpu going into protect mode and stopping the engine

Car overheating on idle


Does the radiator fan come on before it overheats?
And is it boiling over, or just showing hot on the gauge ?
Is the cooling system full of coolant and no air pockets ?
How do you know the thermostat is ok ?

My car is overheatting i changed the waterpump/thermostat/heatercore/reservoir and sensors


Does it slowly overheat while driving down the highway..If so the radiator is probably clogged..It can be partially clogged and cause the car to overheat,,but usually takes a little while...If it overheats in traffic..(stop and go ),,but does fine going down the road,,then it make sure your fan is coming on..

Serpentine belt problem?? heater blowing cold air.


If the serpentine belt broke, the water pump would have also stopped turning, causing coolant to stop flowing...therefore the heater would run cold. Since the belt also turns the alternator, the charging system would also stop working (alt light).
Since nothing is flowing through the engine or radiator, the engine will quickly overheat. Since your engine oil also does a bit of cooling as well as lubrication, oil passing through the overheated block will break down and overheat as well. Hopefully the light came on for that before any internal bearing damage was done. Smoke was due to the overheat.
Your serpentine belt likely is not covered under a warranty, especially after four years.
Hopefully the problem is isolated to just the belt but I do recommend that if you have an automatic transmission you change the fluid in that even if you are not at the change interval recommended. Trans oil is cooled by the cooling system and a severe overheat can chemically change it. Doing a change now will avoid any overheat related trans failure. Since you can't remove all the trans fluid (at best during a change you only remove half) so I recommend using a bottle of lucas trans additive to bolster the remaining fluid.
Good luck!!
