Ok, discovered a coolant leak last night, I think I know where it's coming from but can't be sure (lots of steam, hard to tell at night)

On the passenger side of the block, below the distributor, there's a hose that runs into the firewall. This is a heater hose, right? I'm pretty sure this is it, looked like the coolant was spraying out from right where the hose connects to the block.

Also, to the right of this hose are what look like two sensors. What are their names, and it is possible the leak could be coming from either of them?

Need help ASAP, gotta replace that hose or whatever it is and get my car running tonight

yeah thats a heater hose. the sensor with the single "pin" is the water temp. SENDER and the other sensor is the water temp. SENSOR. it is possible the leak is from there. first examine the heater hose.

 

Ok, just ran the engine to check and the leak is coming from the heater hose, right where it clamps to the block there's a hole in the hose.

Is replacing this a complex operation? I know I'll need to drain the car of any water/coolant from the radiator, and I think I'll remove the intake arm just to give myself some space to work, but is there anything else I need to know besides take off the old hose and clamp on the new one?

Thanks In Advance, need help ASAP!

 

that should do it. if the hose gets stuck like they usually do dont be afraid to cut it off

 

Okay, I drained coolant, replaced the hose, put new hose clamps on (the screw kind, not the kind you have to squeeze together that were already on there), refilled coolant

I thought I got the rear clamp on really good, but when I started the car up, and looked from up top everything looked fine. When I looked underneath though, coolant was dripping...even 5 minutes after i shut the car off. I guess I didn't get the back clamp down enough, or could I have made it too tight? Not much more I can do tonight, which sucks, 'cause I had plans.
