Fan runs for a long long time now since i replaced my old 95 4.6 with a 99 grand marquis engine. When i had the older engine the temp gauge ran between the blue notch and the N in norm, now its between the O and M in norm. After the car starts up it just run none stop.. I have the original T-stat from the Grand Marquis could that be the problem or something else??
