overheating after oil change

stevieM1970 · Dec 30, 2021

Greetings all and grateful of any assistance in advance. Driving and loss of power and oil light came on so put in oil at next garage, still no power so put more oil in and believe over oiled as temperature light went straight to top and fans on. Drained oil and still temperature going to top after half mile. Changed spark plugs and found cable lose which sorted but dont understand why temperature boiling, do I need to drain oil completely or does it need a reset somewhere? baffled dot com so any help gratefully received

Car?
Model?
Engine?
Did you actually check oil level before adding oil?
Coolant level?

The oil light will come on as the engine looses power and the oil pump can’t maintain the pressure. The light indicates oil pressure not amount of oil on the engine.

did you check the dipstick before pouring oil in?
What are you other fluids like?

I wonder if actually the loss of power was loss of oil pressure and something has let go somewhere - possibly head gasket if it overheats that fast tbh

Normally when the oil light comes on, especially when above tick over, oil pressure already way too low.
Any smoke when it was running? If so what colour.

If the temperature is going to the top in a short distance, then does it have coolant in it?

Stop driving it.
Check oil level after engine been standing.
Check coolant.
Check for oil in coolant.
Retitle thread as it confuses!! As you have described the failure is not linked to an oil change!!
Report back.
