It's the one with a single wire. Or you can just go to an auto parts store and actually get the right product.

I agree that the cardboard only masks the problem, I've replaced my temp sensor and thermostat also, and still have the same condition as everybody else.
I have good flow at the radiator cap, so how can the water pump affect heat?
? If the pump is weakening, wouldn't it be heating up quicker?

That is the logical assumption. And in the big picture, yes. A symptom of a failing water pump is the gauge sometimes reading wierd and a lack of heat. This happens because the waterpump can not adequately circulate water everywhere it needs to go. As a result, you get HOT spots and you get COLD spots. The heater is usually one of the first to be effected since it is the highest furthest away point. You won't see this failure by leaking coolant out the pump's weep hole. This failure is the pump's impeller vanes being rusted out to nothing.

So if your engine can't reach operating temperature or you don't have hot heat, chances are something is wrong. It could be -20 outside and the engine will still reach operating temperature just fine. And with a properly working pump and t-stat, it will maintain that temperature.

If you go back and actually read this thread, including the parts where you asked these questions and they were answered, you will still find the answers right there.

That is not going to help you at all. Have you done anything that anyone in this thread has suggested over and over? Your thermostat is stuck open or the pump is failing.

Default Re: temp sender

just to help with this sensor/sender thing everyone seems so confused about. early 90's trucks (and surely beyond that, check a diagram) use a temp SENDER to make the gauge on the dash work. the temp SENSOR is used for the ECM. the SENSOR is located in the "T" near the left of the engine. the SENDER is threaded into the side of the engine block on the drivers side below where the oil sender is. it is most easily accessed from below, although it is not easy to really see at all. it has 1 wire coming off of it.

I hope this helps clear some things up a little bit......
