I'm at my wits end! 2004 SSR runs Hot!!!!
I'm in desperate need of a radiator (new or used). Anyone have one available?
Also need some direction on getting the best price for a water pump.
Anyone know of a good place to buy one?
There are a number of things that will contribute to the SSR running hot..... but before we go there.... let me define what is NOT hot.......
The SSR has a 187 degree thermostat in the INLET to the water pump. This is very well regulated and the aluminum engine likes running at a constant temperature.... The result of the normal 12 degree rise across the engine yeilds a temperature gauge reading of approximately 200 degrees. This is where the thermostat regulates the engine and should be considered the lowest "normal" temperature you will ever encounter.
When you are not using the A/C compressor (air conditioning, defroster and recirculate) the cooling fans are controlled only by the coolant temperature.
The low speed fan will turn on at 226 (increasing) and shut back off at 219 (decreasing). This will give most all "old school" hotrodders the creeps, but it is the way the system was designed to operate.
The high speed fan will come on at 235 (increasing) and shift to low speed at 226 (decreasing). Very seldom does the SSR get hot enough to trip the fan to high speed.
As you can see, the "normal" operating range of the SSR temperature gauge is from 200 to 235. If your truck gets hotter than that, you have a problem someplace in the system.
The A/C will also turn on the cooling fan. Whenever the compressor is asked to operate (A/C or defroster), the computer will turn on the main fan to low speed. If you select "recirculate" or when the A/C system pressures get too high, the main fan will be driven to high speed to satisfy the A/C system needs.
As you can see, turning on the A/C or the defroster will turn on the main fan. The byproduct of the A/C system is that the airflow will hold your temperature at 200 degrees.... period.
In the past 6 years, I have been involved in a lot of SSR cooling system troubleshooting and reverse engineering. There has not been a stock SSR that has ever "needed" a new radiator or a new water pump to solve an overheating issue.
Let's get some particulars on what you are seeing on the gauge and the driving conditions that get you there. We can walk you through this.......
My Best to you,
