cooling

Ok so I just got home from my local AutoZone having spent $75 for a thermostat housing unit. I open up the box and the bolts have rust all over them and there's a gap between the housing and the housing cover. I'm not sure but is it supposed to look like this? My flashlight shines right through...

C an someone tell me what this small black knob in the cooling system is. It is to the right of the radiator. I lost a lot of anti freeze and think it was leaking out from here. the knob was loose so I tightened it. What is it for and how tight should it be ? "Hand Tight"? 2010 Explorer AWD...

Has anyone else noticed that their cooling fan is a bit squeaky. I usually start up my ex while it's in my garage and the squeak coming from the cooling fan is pretty loud. At first I thought it was a squeaky belt but upon closer listening I am pretty sure it's the fan. Is it even worth...

My mother-in-laws explorer has developed this issue, the temp guage climbs and then drops back to normal. I took a look at it the other night, pulled codes: P0121 TP sensor a circuit out of range; P1101 MAF out of range; P1464 AC demand out of self-test range; P1780 TCS out of self test range...

Here is a fan controller circuit, drawn up by Don Doersch, a retired US Navy radioman. It has adjustments for high and low speed. It gets two speeds from two single-speed fans by switching them between series and parallel connection. http://www.flickr.com/photos/27748767@N08/5578415649/ I...

Hey everyone... I keep reading about people RENTING the fan clutch tool for 80 bucks or so. I bought one the other day for 21 dollars at Riebes. Huge time saver and not nearly as expensive as I thought. You will need a 1/2" rachet for it though. The fan shroud said it was right handed...

In the midst of getting parts together for a radiator / thermostat / water outlet job on my truck, the decision of what clamps to use has come up. I've been using the old standard worm drive clamp forever, but especially with some of the ones I have been getting, they do not seem to work too...
