Under normal driving, my oil temp stays well under 210. and water temp is 195. When I turn the A/C on, no matter if I'm moving, flying or parked, the oil temp sneaks past 210, just a hair. Car runs maybe 15 degrees hotter oil temp when I turn on the A/C. The water temp doesn't budge from 195, doesn't go up at all. I never really ran it before, but with the new compressor, I get more than just a squirt of tepid air, I actually get a cooling breeze, so on warm Summer days, I fire it up. I'm not terribly concerned about the temp increase, but I wonder what's causing it. Ok, Dino experts, please weigh in. Dave M.
I must have missed it, but did you install a newly remodeled/rebuilt YORK compressor of the kind that SYNCHRO has posted about, or something else? Mark
My mechanic at Algar did a fantastic job installing a new compressor, we used synchros numbers to order the replacement. Generates enough cold air that I actually get a cool breeze from the lower vents and the ones in the dash. DM
Mine is a '69 Tipo L, thus no a/c so I can't join the discussion, but my nearby vintage Ferrari dealer fabricated a custom a/c modifying reliable Japanese Denso a/c for Dinos. If anyone's interested, I can get you details. I think the set was around $5000 or so. Me ? I enjoy the hot air. Jimmy
I saw an article recently on the new A/C systems being installed on large buildings. They use ice that is frozen at night when power demand is low. During the day the ice is used to cool the building. That gave me a crazy idea. Take out the Dino spare tire and slip in a purpose built, fiberglass, insulated "ice bucket" with a drainage tube at the bottom. Run copper tubing through the ice (and pump water with anti-freeze through it) and patch it into the ventilation system. (That's the complicated part.) Voila, instant A/C. It ought to be good for at least an hour, after which you stop at 7-11 and top the ice back up. (What gas station / c-store doesn't sell ice these days?) No power loss and no extra load on the engine. I'm sure the whole thing wouldn't weigh much more than the spare wheel & tire. Sorry Dave for rambling off-topic.
Do you recall if it was a Right Hand suction or Left hand suction unit? Another way to phrase this is "which part number did you use"? Thank you.
Dave, Back to the original point. There is a good reason for the oil temp to go higher when the air is on. Water temp is not really water temp. It is head temp and head temp is regulated by the thermostat so it should not move much if the thremostat is working. The oil temp is really the oil temp since the sensor is in the oil. The oil is cooled by the circulating water. The water temp will rise because the AC condenser is heating the air that cools the water. Sounds like all is just fine as long as you don't start boiling water. My AC used to work and a similar temp rise occurred. Taking the AC condenser out dropped the oil temp and cut way down on fan use. Good out here where 100+ temps are common. I open my wind wings and just go faster. Nice and cool. John
Thanks John, As i suspected, but, with the bucket full of guys we have here who know more than I ever will about Dinos, it can't hurt to ask. Dave
$5000 for a Nippondenso unit? That is whack. Heck, the brand new TCCI unit I bought was only $306 and was a direct fit for the old York plus it has 40% increased CFM, has superior seals and is universally compatible with refrigerants.
