well I got my car running again, but there's a problem...after my car get's really warm my 2 hoses from my radiator get really tight like there's a lot of pressure in there...I changed my radiator, radiator cap, and thermostat, could it be my water pump not pumpin the coolant through? the top hose is hot and the bottom one is cold(both hoses has a lot of pressure). and my car is not overheating...after i let it cool down it goes back to normal...so i'm just curious what it could be...

 

hum i thought only the upper radiator hose got really tight. Dunno bro maybe fualty thermastat

 

The cooling system operates at above atmospheric pressure when hot. If there is too much pressure, the radiator cap will purge fluid into the overflow bottle.

 

well everything stays where it is..jus that those two hoses are really tight...cause my buddy has GSR too, but doesn' do that...top one is warm, bottom one is a little cooler but you can feel that its warm too...but mine the bottom one is just cold, just a lot of pressure...so i don' tknow

 

i'm thinking its my water pump not makin the fluid circulate....

 

Is the temperature gauge reading hot? It could be the thermostat if you are reading hot and the radiator hoses are not hot.

 

well I just changed my thermostat 3 times already....it's not reading hot just stays at the normal temp... but one of my buddies said its not good to even drive if the hoses get that much pressure in there....

 

...

 

Have you started the car when cold with the radiator cap removed and allowed the thermostat to open? You may have excess air in your system. You can also check the water flow that way. If the system is low on coolant, add it then.

 

if i have air in my system would it cause my hose to build up pressure like that? jw...anyways....how could i get rid of the air in there?

 

You have to fill the cooling system properly. Start the car cold with the radiator cap removed, allow it to come to temperature and open the thermostat (coolant should flow through the radiator at this point), add coolant until the radiator is filled, reinstall the cap, fill the overflow bottle to the Hot level.

 

so I start my car with only a little coolant...then wait until it gets to normal temp..and then add more?

If you remove the radiator cap and the coolant is low, then add colant first. You need to run the car at operating temperature to open the thermostat and open all of the cooling passages. I forgot to mention that you need to set your heater on Hot while doing this, otherwise you can trap air in the heater core.

 

i'll give it a try and see...that could be the problem..cause my hoses sure does get tight and hot....but yeah..that could be it...i'll give it a try...if not then it could be something else
