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.

 

ok thanks

 

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...
