Nic the truck does not have the elec temp control. The coolant system seems to be fine the truck is not overheating and when the valve for the heater core in the hood opens I can feel the heat transfer through the core. This temp blending valve that you talk about. Would that be the white box ontop of the plenum behind the glove box. As far as pics go they need to be on the web somewhere like fototime or something along that line. When you are on you fototime acc you can click on "create link" it will give you an IP address for the photo. Post that IP address in your post and there you have it. Also in the FAQ of this forum it gives a good how-to on posting pics. Thanks Rob
