Message: [QUOTE="brazosdog02, post: 1456082, member: 5446"] I have not REALLY towed anything with my truck, but, in the past, it has spit coolant out the bottle a little. Replacing the cap and keeping the level low solved that. So...I kind of know something is quite right. This past week, I towed my RV (5000 lbs) 500 miles, generally flat Texas terrain. Let me tell you that keeping it at 65mph required a bit of effort on my end. Honestly, my 2013 5.4L Expedition pulls and towed it better than my diesel. I found that odd. Even with the slightest grade, it often required shifting out of OD and giving 35psi of boost just to hold the speed. I was surprised. My coolant temperature stayed at 200-210 most of the way and I didn't noticed any crazy spikes in temperature when giving it a lot of boost. The oil temperature is normally within 10 degrees of the coolant, but towing, it was 20-30 higher. Also, it puked about a gallon of coolant out of the bottle total. (i have a coolant bypass installed and I backflushed early on, but it may have been too late) This truck is a 2005 and I have no idea exactly what the issue is or if it's fixable. I am trying to get an idea of cost to find out if I want to fix it, or just leave it alone and trade it in within 2 years. My assessment is that the Oil cooler is partially plugged and the heads may be lifting.... Thoughts? Im only considering fixing it because the truck looks brand new and has everything I like and need in a pickup....except the ability to tow worth a damn and be reliable. [/QUOTE]
