I discovered a slight leak coming from the oil cooler lines from my '99 Crown Vic PI. The lines will be cheap and easy to replace, but at the same time I learned that the oil cooler assembly can be deleted entirely.
Though this would require more work, I wondered if eliminating the oil cooler would cause the car to warm up faster, and thus result in better MPG? I use the car primarily for relatively short trips, and the engine usually gets up to operating temperature, but I thought that deleting the oil cooler would get it up to operating temperature faster, and thus result in better MPG.
I know that there is a transmission cooler on this model as well, I do not know if it can be deleted, but if so, would this also get transmission fluid to operating temperature faster and also result in improved MPG?
Please note that I have the 4.6 modular engine and I never intend to tow anything with this vehicle, and the vehicle will not see extensive idling in hot conditions.
