92 civic si. The fuse for the fan was blown, so I replaced that. The fan works now but both hoses are still ridiculously hot and the upper hose is swollen and hard as a rock. The car isn't over heating though. This problem just started a few days ago. I had a check engine light come on, but for some reason the jumper isn't under the passenger side kick panel and I'm not sure where else it would be.

The check engine light hasn't come on for 2 days now but the hoses are still hot and swollen.

You may have a thermostat that is closed. Check that first.

LMAO, nah the Ek's are the most sexiest B*****s

nothing_shocking

how would that happen? i thought if honda thermostats failed, they fail open?

marcs1337

hoses are cheap and easy to replace...why take a chance...just replace them

SOHC_4dr

its possible for them to stick closed, but if it was the issue he should be overheating and he isnt. OP also has a talon turbo on it thats oil and water cooled. does anyone know if these turbos been able to cause any coolant issues? im helping the OP fix his car and i to am stumped

nothing_shocking

why would the hoses being bad cause the coolant to be so hot?

dumafit

they could just be old, especially if the car has been sitting for a while with no coolant flowing through it, it hardens up and when coolant does flow, it cracks it and gets it super spongy, it will pop soon so change it

-=ZAK=-

i know form experience lol this happened to me

nothing_shocking

i've been driving it everyday for the past 2 months with no problem at all.

(edit) what about the radiator cap? could that cause this maybe?

marcs1337

i was talking more about if the hoses are stiff with no flex in them, then you should replace them.

nothing_shocking

well with how hard the upper hose gets there is no flex, then again, it's also really short. the lower hose feels fine, it's just really hot whereas before it would be cool until you felt closer to the engine.

green99civic

the lower hose should stay cold until the thermostat is opened that's a great way to test your thermostat is just sit there revein your engine to wait like 5 mins with engine on and check to see if your bottom radiator hose turns hot if so then the thermostat is working correctly.

nothing_shocking

i don't get that... before this started, the lower hose would stay cool, now it gets as hot as the upper.

SOHC_4dr

the lower is suppose to stay cool(or slightly warm) or else the radiator isnt doing its job. also it unlikely the thermostat because his car isnt overheating. we replaced his cap and still no luck.

I see this all the time on domstic cars at my shop ( i know i know dont beat me); when is the last time you flushed the block? Do you have a over flow catch?

nothing_shocking

i do have an overflow tank, but there's next to nothing in it. i did have it between the min and max marks, but then it all disappeared...

SOHC_4dr

flushing the block isnt required maintnance so it hasnt been done on his car. there is a resevoir tank and its usually near empty with no adverse affects. like we said before, no code, fan works, no overheating. just a hard upper hose. i think Shocking is gonna replace the hoses sometime

nothing_shocking

oh i am huh? i didn't know that...

SOHC_4dr

*cough* eventually *cough*

nothing_shocking

i really don't think thats the problem though... it just doesn't make any sense...

SOHC_4dr

agreed. well lets let it go untill something really ****s up

nothing_shocking

yeah. head gasket

SOHC_4dr

we went over this. that isnt it
