The info on the Gates hoses is no longer valid, they have become some of the worst hoses on the market. I have had some of them delaminate. The post is from 13 years ago, today I use OE only for coolant hose, the JD coolant is still a great coolant.

Partial change on our Expedition as it sprang a leak in a heater hose. I replaced about 25% with new G05 coolant to top off after draining enough to do the repairs. It had a drain and fill last year so I'm going to call this good for an extra year before it's next drain and fill.

2013 Ford flex 3.5 Ecoboost 177K miles.
Out: unknown, looked like a really faint orange, probably OEM coolant.
In: Motorcraft yellow concentrate mixed 50/50 with distilled water. Also replaced thermostat with an OEM unit. It was so nice doing a coolant flush/service on a more modern vehicle for once. System was still nice and clean; I'm used to flushing out sewer water from cooling systems.
- first time using the Motorcraft yellow coolant, which had way more of a classic green color to it than yellow, thought that was kind of odd.

Nothing’s safe anymore. But if OE is NLA, now what?
Finally got around to doing a change of chemistry coolant change (standard life HD to DD PowerCool+ extended life OAT coolant) in my 96 Prevost XL40' bus/motorhome. System holds 24 gals. I did 5 dump & fills with distilled water. Then the 6th one I filled it with 12.5 gals of DD PowerCool+ and screwed on a blank h2o filter. I can only drain about 12-14 gals each time I do a dump and fill. I also need to drive it at least 20 miles to get the thermostats (190*f) to open each time. 4 days and 70+ gals of distilled water for this job.
The DD PowerCool+ I used was the concentrate, not the pre-mixed.
Next dump and fill was 5.3L in the 51 pickup.
It got Dexcool concentrate & distilled h2o
It got Dexcool concentrate & distilled h2o
did a dump & fill (1 gal) on the C5 too. Went back with Dexcool pre-mix.
tomorrow the Yukon 6.2L gets dump & fill and drained enough so as to replace a hose and a new plastic surge tank.
Going back in w/Dexcool.

Pulled the peacock and Drained out about a year old Peak 10x + residual Dexcool left in block from the 4.8 to 6.0 motor swap last year.
Scrubbed the coolant bottle well with CLR then Dawn and flushed a ton.
Refilled with 50/50 Peak 10x. Will top off with some full strength concentrate tomorrow or tonight to capture any residual water in the bottom of the bottle.

Original rad. It has no radiator cap and is filled through the jug. The jug is pressurized and part of the circulation system. Crazy as it sounds the 2008 radiator has no drain petcock. Draining is achieved by taking off the lower hose at the rad.
I used a remote hose clamp expander and lowered it to the clamp. I also removed part of the plastic fender liner to be able to pull the hose off the rad.
I tested the original as over 55% antifreeze. It’s Prestone Dexcool 5 years old. The total volume is about 4.5 gallons. I drained the rad and jug ( the jug drains totally with the rad). Approx.1.5 gallons came out). I then filled the rad through the jug with 1.5 gallons of distilled water. Idled the motor for about a half hour, made sure the top rad hose was hot and that the rear heat was warm.
Let the engine cool off and then tested the concentration. It was about 33%. Drained another 1.5 gallons and filled with 1.5 gallons of concentrated Dexcool made by Prestone. Idled the engine again while I did some other maintenance. Will check the final concentration in the morning.

Here is the clamp expander which I used from above the radiator to the bottom hose. The bottom hose connection is shown inside the red circle. There is not much room to get pliers or a pair of clamp piers down in there.
Since there is no radiator cap, the engine is filled through the coolant jug.
