today my temperature gauge went all the way to the red. i turned off my car and just sat there for about 30 minutes for it to cool down. and i noticed in my coolant there is nothing attached to the cap? so no coolant is going anywhere. how can i fix this? please help me a.s.a.p. its my daily driver and i cant bare to have it overheat.

 

replace the hose?

 

well that tube from the cap is meant to go to the overflow bottle. have you got coolant in the system? its probably heating up, then just spitting the coolant out since it isnt hooked to the overflow at all. and it will be evaporating etc as well since theres an opening in the system.

i would replace that with a piece of hose to the overflow bottle and top up the whole system and see how you go. if you arent confident yourself, take it somewhere and get the system all flushed out and fresh coolant all thru it, might as well while you;re at it.

 

Could be a leak, theres many places a radiator could be leaking at, Take off your under guard thing, and see if there coolant leaking from the bottom, I think the coolant thats not leading anywhere is the coolant overfill reservoir, like stated above its not supposed to lead anywhere. If you took off the radiator cap and its full and your still overheating, maybe its the water pump? You should get it checked out by a mechanic

 

also check to see if the thermostat isnt stuck closed

 

based on the initial post i will give you $1000 if the OP can test for a stuck thermostat. I will give you $500 if he can locate the thermostat without help.

 

Oh noes!!! I gots no hoses on mah caps! Wat doos I doos?
