"air tight" upper radiator hose

so my car overheats every other month or so, normally i just bleed the system, and its fine
but this time i want to fix it, not just a temporary solution




when the car overheats, the hose is all squeezed up
but after i let it cool down, open up the cap, the hose goes back to normal
i dont notice this when the car is in "normal" condition
i duno if this help, but the lower radiator hose is cold after i have driven the car for a period of time

what could be wrong?

its a 91 hatch, stock KA if that makes a difference

is it leaking coolant ? could be the water pump going...

But, a new thermostat is like 5-10 bucks, might as well try it, or a new radiator cap.

dude i had the same problem over the winter. the hose you have on there probably isn't the one intended. Go to autozone or whatever and get a new 240sx upper hose, believe me the hose is your issue.. I replaced my hose after i had your issue and haven't overheated since.. gl

yes get a hose! obviously that is part of your prob. Hoses are engineered to withstand certain pressures and what not. also since your pretty much stock, and your radiator isnt leaking, tak it to a radiator shop and have them flush it.

I've never seen a upper radiator hose do that, i've seen it happen to the lower hose when someone leaves the coil spring out of the hose. You could prevent this just by putting one of the springs that most lower hoses has in them. But you need to find out where the vacuum in your cooling system is coming from. Your radiator cap should relieve that vacuum, check or replace your cap. The collapsed hose isn't the problem, it's just a sign that your cooling system is losing water, then your radiator cap isn't relieving the vacuum that results from the lose of that coolant.

i've seen that before, but only after the car had cooled down.

the tube to the overflow from the neck was plugged up. try blowing through the tube from the reservior end with the cap off,,and replace the cap with a new one. (cheapest and easiest things first)

The hose is meant to withstand pressure, that's true, but any hose, new or old, of that diameter is going to get sucked together if there is a vacuum present. Don't just throw new parts at it, find out why there is a vacuum present in you cooling system, where does the coolant go. The collasped hose is the symptom, you need to find the problem.

mine did this when i first got mine we replaced the hoses radiator water pump and the thermostat and then it still did it. we did a compression test it came out just fine. all mine was was an air pocket in the motor the radiator burped one good time and never had a problem after that. we let it run for about 10 min with out the radiator cap on and that seemed to fix the problem.
