I've I've got the kits for the inline thermostat, send me your email address and a private message and I'll send you the installation instructions so you can look it over. Here's my experience with the inline thermostat today. I'm driving from Lynchburg Virginia to Charleston South Carolina going down on I-95 and it's hot today, I'm reading air temperatures between 96 and 98 Degrees, truck is running 194 degrees with the air conditioning full blast going 75 miles an hour. the truck is a 2000 with 250000 miles on the clock with the original engine, she has a safari Grill and I run with both of the weather strips at the back of the hood removed to let the hot air out of the engine compartment

I just I just had to stop for gas, 313 miles on 18.97 gallons going 75 miles an hour, that 16.5 miles per gallon on a 20 year old truck with 250,000 miles on it

by the way, all the oxygen sensors on this one are dead and I just haven't had time to replace them due to other project, doesn't seem to be affecting the mileage that much

the two thick ones at the back of the engine compartment that the hood steals against. They are designed to force fresh air flow going into the AC unit to flow through the cowl Grille with the filter installed. I always run my AC on recirculation so I don't need to pull fresh air and I would rather let the hot air out from under the hood. My dad knew the fleet superintendent for the city I grew up in in Louisiana, he told us he had to put hood scoops on the city facing backwards to let the hot air out from under the hood to keep them from overheating, it's a trick I've remembered ever since

You're doing the exact opposite of what you think. Generally the rear of the hood near the windshield is a high pressure area, so you're reducing your radiator efficiency by removing those. If you're trying to extract air from the engine bay you want the vents to be more in the middle of the hood behind the radiator.

The base of the windshield is only a high pressure area at speeds above about 50 mph, not typically the speed Discos have overheating issues. Removing the weatherstrip lets the hot air out at idle and low speeds. Even at speeds above 50 I doubt the high pressure effect is negative relative to cooling if it allows some fresh air in to the engine bay. On the old city trucks his problem was also overheating while sitting in traffic idling.

Yes, cared for very well by the previous owners. Couple sets of headgaskets of course but I am pretty sure the engine has never been out and I am on the original rings and bearings. Normal wear items of course - starter, cooling system stuff, wires, alternator, ps pump, idler bearings. I think the CPS is original, front driveshaft has grease zerks so I bet it has been replaced or rebuilt.
