SOURCE: radiator leak

if you want to make sure you can put some soap bubles on the hose and see where the leak has actually taken place as a first step in diagnostic.

just pour the soap on the top and you can see (not inside the radiator), once it blows then there is your leakage.

either the radiator itself is the prob or the hose

My 1997 buick park avenue, is getting hot. upper radiator hose gets under extreme pressue, stem coming from radiator hose/radiator inlet, leaks coolant only after shut off??

Normal pressure is 16 psi controlled by the radiator or coolant tank filler cap. Sometimes a cap fails to hold the proper pressure this is most noticeable at engine shut off, water and steam blow out

I have a 1993 buick park ave and it is leaking antifreeze

If its leaking, its getting over heated because of no water. If its leaking water, you need to check the hoses first, usually old hoses between the radiator and engine burst or have slow leaks. This can not be tested at home, so replacing them is easier, than taking it in for testing. It could be a hose clamp, they are located at the top and bottom of the hoses and just require a screw driver to tighten. Could be the water pump but that makes a whinning noise that you can hear if the radio is not on high. The radiator could have a leak also. best way to find out is fill the water up, and turn the car on and see where its leaking, you might need assistance from someone to raise the rpms by stepping on the gas, make sure its in park. overheating beyond that if all that is good, could be your freeze plug located at the back of the engine in deteriorated. If the engine block had a crack it would usually seize. The block above the engine is wear the cooling takes place, so if the block is cracked it will cause the oil and water to mix and cause overheating, but that is not usually tons of water loss. I would start with the hoses and run the engine and look to see if one is bubbling or leaking. you can spray water on it to see it bubble where the leak is. hoses range from 40-60 dollars because they have insulation coils in them. oh, check the radiator plug at the bottom of the radiator, it might be open or blown.

Follow the upper radiator hose back to the engine. Where the hose connects to should be the thermostat housing.

My 97 buick park avenue is leaking and causing the temp to go up where can i find the leak at?

It could be a number of places. I assume you mean that the coolant is leaking. You need to get it pressure tested to find the leak if it is not "dripping" where you can see it.

Leaks small amount of coolant, but I don't see

Check the engine oil, see if the level is going up and what the condition is. you can take the oil cap off and inspect under it. if there is a milky fluid then the antifreeze is leaking in to your engine crank case which is bad for the engine bearing. The other thing to also check is the transmission fluid. make sure that its till bright red and not over filled to make sure it's not leaking in to your transmission through the transmission cooler which is apart of the radiator too. Good luck and keep me posted. Be glad to help.
