cooling fans finally fixed...

My 88 did not like to turn the fans on when the temps got hot, but worked fine doing the KOEO test as well as upon start up and when I turn on the defrost, so I know the relays are working. I replaced the ECT switch about two years ago and it never fixed it, so this morning I went out with a new water pump, thermostat and housing and a used ECt from a junkyard 89 Crown Vic. When it was apart I flushed out the intake coolant lines and the heater core lines, I also picked up a junkyard heavy duty radiator from an 88 Mustang Gt that was practically brand new. Put it all back together purged the system out and let it run with no defrost on. Temps got to about 3/4 to the top and Finally the fans kicked on by themselves! I was ecstatic! I think the "new" ECt from two years ago was never good to begin with, the junkyard Ford part worked like a charm, maybeI finally have it fixed, just wanted to pass along the outcome.

My experience is that many, if not most, aftermarket sensors like ECT, IAT, etc are absolute junk and dont work even brand new out of the box.

I'm starting to think the same thing, I used the rockauto list of vehicles that the ECT worked on and simply found one in the junkyard. Think I might do this with other items as well. Drove in to work today with 90 degree temps outside and all was perfect in the cooling world. Gauge read at about 1/3 way from the bottom, never raised above that. Much better

Agreed. But the question is, what happens when that is all we have, is aftermarket?

Not long ago I was having oil pressure issues; i.e. leaking from the dipstick tube, etc. Most solutions involve the PCV valve; I installed an aftermarket one and it did not get any better. Following the advice of Jeff K and many others I hunted down the proper Motorcraft part, can’t offhand recall that number. I also replaced the hoses to and from it. Spoiler alert: the leaks stopped, or at least were greatly diminished.

It wasn’t cheap, but I don’t care about that. I worry about the day when a replacement is either not available or very expensive. Makes me want to buy a half dozen right now of the Motorcraft ones, and then sit on them.

This also creates problems too, for anyone who needs that part.

Here in Phoenix we once had 97 salvage yards. We now have about 25. Much of that is because vehicles are increasingly becoming disposable, with few good parts left after a collision. Also, the main street many were found on—Broadway Rd—was recently widened, which forced many out of business.

There was a time here when I had my go-to places to find parts. Most of those are gone, now.

Sounds about right.

Last year my rear brakes lights would stay on so I replaced the switch and then they would never come on when I hit the brakes.
So I had to replace the new switch with another new switch just to get the brakes lights to work again.

I have never had a problem with 80's Ford brake light switches, but I have had several issues over the years with the wires going to the switch breaking due to the constant flexing. Sometimes these breaks have been internal, with the wires looking fine externally, sometimes the wires have broken off at the switch connector.
