what kind of "pipe"? solid metal pipe, or flexible rubber "pipe"? number one cause is from aged rubber that dries out and cracks. loose hose clamps, wore a hole through it, cracked thermostat housing, etc.
No. The only times the radiator would leak is if it was damaged, defective, or corroded.
Thermostat stuck closed.
Low coolant, stuck thermostat, failed waterpump, plugged radiator, inoperative radiator fans, etc.
U NEED A THERMOSTAT. THAT IS WHAT HOLDS THE COOLANT IN THE RADIATOR, SO IT CAN COOL DOWN BEFORE IT GOES BACK IN THE MOTOR.
you looked at it Timing out of adjustment can cause overheating.
Thermostat would be my first guess, If not is a fan blown, do a radiator flush?
Overeheating is usually caused by a bad thermostat, blocked radiator or leaking headgasket.
low coolant ,froze thermostat ,leaks in hoses ,radiator
clogged radiator or bad water pump
No. The thermostat controls the flow of water through the radiator, not the heating core. Using a thermostat with a higher temperature rating delay the opening of the thermostat (and the flow of water to the radiator) until that higher temperature is reached. This will cause the coolant to run hotter.
Blocked radiator, low on coolant, stuck thermostat, air in cooling system
More than likely it needs a new thermostat and the radiator back flushed.
