What are the possiblilities that could happen when your engine overheats and you keep driving?
Is it possible it doesnt run anymore because the pistons weld onto the cylinder wall?
Her car has about 90000 miles and she bought it from a old lady a few months ago.
She said that there is no more water in the resevor tank.. Could there be a leak and why did the engine overheat??
Give me ALL the possibilities.
Possibilities for coolant leak:
-Heater Core hose
-Heater core leak
It's possible that the pistons have welded themselves to the cylinder wall. Other possibilities include:
-When it starts to over-heat, the pistons expand and start grabbing the wall scuffing both the pistons and the wall, so compression can't be made anymore.
-When the piston started to bite the wall a rod may have snapped
-Same as above but may have damaged the crank
-Could have warped the heads/cracked the heads
Pretty much anything can break when it starts to over-heat.
When looking at why an engine over-heated, you don't look at the resevoir. You look in the rad, the resevoir doesn't serve any purpose when it comes to cooling. If the rad's dry then you have your reason as to why it over-heated.
Over-heating is caused by a stuck thermostat, bad waterpump or low coolant. (clogged passages can cause it too, though very un-common.)
