Although the 3.7 V6 would probably physically fit, I'm not sure you could swap because of the PCM programming. The original 3.5 has variable valve timing only on the intake side whereas the 3.7 has twin independent variable cam timing. As a result, the 3.7 produces 40 more horsepower and 30 foot-pounds additional torque. I would expect that the PCM tuning would have to be significantly different (fuel mapping, etc.) to account for those differences.

 

The bigger question is why replace an engine rather than a couple of head gaskets? Sure a used engine may not be expensive but the labor to install it will be and you don't know what problems you may inherit with a used engine - the previous owner may have never changed the oil. Head gaskets aren't expensive but again the labor costs could be. The difference is that you know the history of your own engine. And pulling heads on a Cyclone V6 is actually not that difficult (I've seen it done in a driveway) so you could end up saving many hundreds of dollars.

Forgot to mention I just bought the Edge 1 month ago..I don't know too much about the service history other than oil was clean and it ran fine until it broke down.

It could very well just be it blew a head gasket but considering the engine has 130k miles maybe just finding a good low mileage donor would be an upgrade

at a fairly resealable price to redo the heads and gaskets?

On the 4th July my 8.5 pregnant wife and I were driving when the engine starting ticking at high RPM's. Sounded like a lifter.

As soon as I mentioned it to her the car starting hesitating and died. Car overheated...Thank god I was able to pull over and call AAA.

Looks like I have coolant in the oil and need at the very least new head gaskets. Im just going to replace the entire engine as they

are not too expensive used.

1. I see options for 8th digit C w/o oil cooler what type engine do I need?

2. What engines will work for my Edge?
