Ok I bought a Koyo radiator and installed it last night pretty easy. However the lower radiator hose didn't get replaced because I didn't know how I could get it from the engine side. So I left the old one on. I went out last night, got the low coolant buzzer and went right home. I opened the hood assuming that I had a leak....which I did at the lower hose and the radiator. Then I heard a loud hissing noise for about five or six seconds.....HELP whats the hissing sound? Any tricks on replacing the lower hose? HELP!!!!!

When you took off the fan & shroud to install the radiator, you should have been able to get to the lower hose.
Is the old hose bonded onto the pump housing outlet? - Just cut & scrape it off..

anytime you are putting ina new rad it is a perfect time to do the hoses

I didn't remove the fan...how do I remove it..... Also what do you think the hissing noise was?

The hissing was probably the air leaking out of the line at the same time it was leaking.

Wow - you replaced the radiator without pulling the fan?

The trick to removing the fan is using a 10mm box end wrench.
An open end wrench will round off the 4 nuts.
Pull the fan before loosening the belts. That makes it easier to keep the fan pulley from spinning.

My clutch fan was seized on and I ended up stripping the nuts. I had to use my neighbors air hammer to get them off. It wasnt very fun.

Use a big slotted screwdriver to pry in between two other nuts (or studs if the nuts are off) to keep the pulley still while trying to loosen up the nuts/bolts...

If you can't fix the hose leak with a clamp, use some black RTV on the new rad pipe (after cleaning) before shoving the hose back on. Let cure for at least 30 minutes before pressurizing...
