i have the wabasto in my 04 dually, it has been working great now for 5 years, my dealer sells and installs them. when i picked up the 07 they wanted to try the espar and it wasn't heating up as fast as the wabasto, they checked everything out and said it was fine. last summer i finished ripping the egr cooler out and this winter the espar worked way better! i guess that pump didn't like pushing coolant through that stupid maze of a cooler.
