[DeTomaso] Radiator drain and new hoses

[Garth Rodericks]

I didn't know they had blue-stripe. I learn something new on this list every week. 
 
Blue-Stripe Specs: 
3,000 to 6000 PSI
Temperature Range: -40°F to +250°F (-40°C to +121°C)

Green-Stripe Specs:
95 PSI 
Temperature rating: –40°F to +257°F (–40°C to +125°C)
http://www.gates.com/brochure.cfm?brochure=1494&location_id=1175
 
FWIW, I think the Blue-stripe hose is overkill as that's designed for extremely high 
pressure, high impulse applications such as hydrostatic transmissions. And, since the 
Green-Stripe hose has a higher temperature rating and your cooling system will never see 
more than about 14psi of pressure before the radiator cap relieves pressure to the overflow 
tank, there's likely no need for a 3000 PSI hose (or the additional cost).
 
Cheers!

There are both colors.
I have Gates Green Stripe on the car now which looks very old.  
I was told Gates has a "Blue Stripe" hose that is thicker and even better as far a durability which is why I asked.  It is stiffer which makes it harder to apply.

<<< how hard is it to install the Gates Blue stripe hose? >>>
 
FWIW, it's called "Green-stripe" hose.
 
<<< I've used a smidgen of Dawn Dish washing liquid as a lubricant on the male parts to 
help facilitate easier installation, I don't see what a little WD-$0 could hurt either >>>
 
I often coat both the inside of the hose and the male fitting with silicone (little aerosol can) 
to ease assembly; completely benign to the hose too. A mechanic neighbor turned me on 
to this trick years ago.
 
<<< Consider double hose clamps as well and make sure that the srcew/tightener part 
isn't facing down underneath the car where it might hit a speed bump or road debris. >>>
 
Good advice about clamp positioning.  Not a lot of room for double clamps in some spots. 
Instead of double clamping, I used High-Torque stainless hose clamps throughout my car 
and have not had a leak in 4 years and 22,000 miles.
