I went to change the oil in my 99 si today and I noticed the upper rad hose was swollen up pretty bad. I never had this happen. Car does not over heat , smoke , or loose and anti freeze. Does this just sound like a weak hose? Thanks guys

could just be old hose getting weak
what does it look like when cold

Yeah man, I would just say it's an old hose getting weak. I have a 00 SI and my upper hose looked like it was going to bust. It was a pretty old hose that just needed a replacement.

i popped the rad cap and let the car cool down and it started to shrink back to normal

Thats what i was thinking as well

A swollen hose is 99% of the time just an old stretched out hose.

There cheap to replace might as well just do that. Better than being stranded in the middle of no where worst case scenerio.

Yes, just get an OEM replacement.

I noticed today that car is not heating up as fast ? Is it possibly the thermostat causing a swelling? It seems like there is a lot of pressure in the system

I'm assuming you have some of the original parts still on the car. It's safe to say you should change your t-stat, hoses, and if you haven't done so get the timing belt/waterpump service done as well.

Replace the T-stat while you are there. They are pretty cheap as well.

You will need to drain/bleed the system anyways, so it's not really any added work.

when i buy a car part of the tune up i do is replace the t stat, any hoses that look/feel old, coolant flush, oil change, plugs/cap/rotor, trans flush, regardless of what the previous owner says is done to it.

Get an OEM thermostat.

oil eats hoses, so look for any errant oil coming from valve cover or something

only hose I had to replace recently was one right underneath distributor...soaked in oil and swollen....

98civdx

yes, do this!

I always use oem tstats. Aftermarket are junk . Replaced the hose today and everything seems fine

A autozone t stat bit me in the ***.

I think everybody covered things pretty good. I will only add that if you shop around/online you could even upgrade your hoses. I bought a 5 pc kit of silicone hoses for $70 shipped

Arthas

LOL mine is like this right now! Im just waiting for the day it gives out. Its swollen and mushy, my dizzy inner seal is leaking.



OP right now would be a good time to get some silicone hoses
