The duty c solenoid cycles on and off. Anytime you see something about d duty solenoid usually eans it has so any cycles a minute, and is controled by computer of some kind Solenoids only do open and close, they dont do anything in the middle. The stis center differntianl control are a rheostat that sends a to the puter, then the puter sands the cycle speed to the solenoid. NOw when the car is in low gear, you can still make tight turns, so the computer has not been bypassed, as it is still reading the differnt differential speeds and compensating for that. If that is all that wire does and nothing more (and it most likley goes to ground- guessing) then you can have 50/50 split with driveability. Pluging into the c solenoid directly, you have 50/50 locked up all the time... hrmm a 3 position switch. off, 4wd, 4wd Locked.... nipper

dont understand your question .. if you dont know where it is, you really need to open your hood more often and learn how to check your own fluid levels. Hydraulic pumps start chewing themselves up real fats once they start going. Have you ever checked your fluid levels? if you let the pump run low or dry .. the pump will self destruct. nipper

could be just an old belt that did not like the engine cleaner. either tighten the belt or replace it. nipper -
Glad you are ok, but tomorrow make yourself a Doctor apointment and get checked out anyway... nipper

If i am correct, this used to be called a manifold absolute pressure sensor. Its a dual purpose sensor. It flips between manifold pressure and atmospheric pressure. It will affect perforamnce espeically in elevation changes. The solenoid you speak of being stuck means the car is not sensing manifold vaccume. This may be a pricey item at the dealer, but cheaper at a junkyard. nipper

Electric Water Pump in subarus?
nipper replied to suburpy's topic in Old Gen.: 80's GL/DL/XT/Loyales...
seems like alot of money for a 3hp gain. Thats the estmate on how much HP it takes to run the cooling system. On the reverse side there is no free ride. How much energy does it take pump? edit (answered my own qyestion) > i did the math.. its life is 100000 miles at 50mph and it uses 0.15 HP to operate. In the next few years OE's will be going to electric waterpumps and electric thermostats. Personally i dont see any advantage to it on a subaru engine. i can see the pros and cons. Beisdes the enigne compartment is tight enough already, where would you put it?Now if you were making a high HP turbo motor, the fact that it can run after shutdown is a huge plus. nipper -
Well some good news, in my latest issue of Automotive Engineering International (trade mag for SAE Members) full drive by wire is put off till 2015. Brake by wire has too many iissues, but you will see it in hybirds on the rear brakes. Shift by wire is being delayed. Parking brakes are going to be operated by wire. 42volt electrical systems which are required for the other two by wire systems has been delayed too due to extensive costs. nipper

Go to a mom and pop autostore and ask them what brand pipes they use. If they are walker pipes, i would buy from the autoparts store. If they are not, i would go to the dealer. And to save yourself some greif, i would replace everything from the cat back and be done with it. i agree if OE parts lasted for so long, i would go that route. Walker is sometimes a supplier to OE thats why i recomend them. nipper

Actually before you do that, throw a mechanical gauge on the car, dont always trust factory gauges. Get a true reading. After that, i dont know what to tell you, i would replace the pump, not reseal it. What determins oil pressure is the wear on the main and connecting rod bearings. The more wear there is the lower the pressure. You may try a thicker oil. Thats what i would do. nipper
