amc49 Can't drive these without the fans CAN but just like all the others who overheat over and over thinking they'll fix it when the next check comes in you'll end up in the scrap pile.

The fan motors themselves rarely fail, it is the cooling electrical circuit on top that controls them that fails left and right.

I myself strongly suspect that some of the aftermarket head suppliers do nothing to the heads at all other than fix them, nothing done for that dropping issue at all. Just lip service.

sailor Look/post in General Tech Chat for more help with the fans, the fans themselves are SELDOM a failure point.

Lack of low speed fan operation is a common issue, and the resistor/connector to it is only one of the possible causes.

Sorry to hear you have to deal with this again, overheating on those can cause head gasket troubles as well so you may have dodged one bullet only to be hit by another.

2nd head dropped a valve! :(

Bought a cheap 2004 Focus LX for my kids to drive.

I started reading your Forums and asked several colleagues including mechanics about the SPI head failure and everyone said they never heard of it. Three months later, my engined failed because of the dropped valve guide. I bought a reman head from justheads. One year later, same thing.

Both times it failed on a hot day. I realized that the cooling fans don't work. I have to order another one. This time I will get a new aftermarket casting. I will also need to fix the fans. The resistor looks ok. I think I will buy an aftermarket fan to replace it.

Dropped vavle seat

Of course it has! 140,000km (88,000 miles). #4 cylinder. Should be a class-action lawsuit launched against Ford.
Not sure if it's worth repairing, given the value of the vehicle.

Wulff45 143K. I just swapped a new head on, due to a valve seat loose enough to keep the valve from closing part of the time. Had a shiny mark around the edge of the valve relief in the piston, where the valve/seat was making slight contact, and the seat is visibly cracked at the point it is closest to the exhaust valve.

No, it didn't drop a seat, but it was about to do so.

I purchased a new head casting from J&C Enterprises, ( ) extremely pleased with it. Highly recommended.
