Here's an article discussing three types of hose clamps.
Three Types of Hose Clamps for Cooling Systems: Spring Vs. Worm Vs. T-Bolt (With Video)
Learn the difference between spring, worm, and t-bolt hose clamps and why spring clamps are better for use on the hoses in your car's cooling system. Also, learn how to take the spring clamps off with specialty tools.axleaddict.com
Rite of passage. It’s cruiser reminding you blood sacrifices are required from time to time.And finally look out for the smaller versions, catch your finger, arm or whatever on the protruding edge and they can open you up like a can of sardines!!
Also, most hose clamps are only good to about 64 lb-in of torque on the screw. The heavy duty ones are only good to about 95 lb-in.Might be a good place to mention this (no hijack intended):
I replaced all of the engine bay water heater hoses along with most of the clamps on my 97 model FZJ80 with Gates Power Grip Hose "clamps". These clamps look like wide black bands and are made of a specific type of thick heat shrink plastic. Originally developed and designed for over-the-road truck fleets to decrease cold leaks.
The type of Gates heat shrink clamps used for large trucks are shipped to the truck manufacturer on dry ice and stored in deep freezers until they're installed. They're only pulled out when the truck reaches a specific section of the assembly line where the tech has 30 seconds (each) to get the clamps from the freezer onto the hose connection as they're designed to shink at room temperature (personal communication with a Gates tech).
The aftermarket Gates Power Grip clamps however are made from a different formulation of thermoplastic that's stable at room temperature and needs to be heated (heat gun or small torch) to shrink.
Altogether I replaced around 20 hose clamps of different sizes in the engine bay (1FZFE) with the Gates Power Grip clamps, not one drip on first cold start (been meaning to start a thread, got a bunch of photos).
FWIW

Nothing proven, but people like oil eater for that purpose. Ask your local NAPA folks. Maybe your NAPA with be like mine and the employees will be helpful and knowledgeable. They usually have some various driveway degreasers. Or try Lowes/ HD. Probably a degreaser followed by a pressure washer? If it’s only asphalt then you won’t have to work too hard. But if it’s concrete and the stain is very prominent you might have to work at it. GL!Same thing happened to me recently. It turned out to be the aux trans cooler connections. They were crusty with rust and leaking after 5-10min after warming up.
off topic, does anyone have a good solution to cleanup trans fluid from the asphal?
I think the Toyota clamps are worth it…except for the ones on the hoses by the firewall…those are difficult.Most of my clamps are the Gates Constant Tension clamps but they are still tightened like a worm clamp. I had one leak in the cold. Sure wish I had used the spring style constant tension. I guess you're suppose to use a torque driver/wrench with these but I didn't. So, maybe it was my fault. Either way, I don't think I saved much going this route and wouldn't do it again.
