Last time I was haulin a trailer I was pullin a 13k lb dump trailer and with my chip on high I could not keep the truck coolant very cool.was about ready to overheat. It runs about 190 all the time when not pullin and the fan runs alot.. I dont think it should run that hot when just drivin around. Maby i need to replace the thermostate. I cleaned the radiator and intercooler but it still run to hot I think. Is this normal to run that hot or am i just :cookoo:.

I did just put a needle valve on the line to the gauge, and it's open a little. can this valve be causing my problem? and is it ok to drop pressure for a sec or two? i going to open the valve full open untill i get fuel tomarrow. ]]> Reliablity / Performance little white yj 622 http://forum.mopar1973man.com/showthread.php/2228-Air-dog-problems http://forum.mopar1973man.com/showthread.php/2212-Lets-see-your-homemade-air-intake..?goto=newpost Mon, 16 Aug 2010 23:10:51 GMT I wanting to make my own air intake since the aftermarket ones are SO expensive.

I found my recent 2000 2500 truck aquisition very annoying constantly going in and out of lockup in the city or in hilly terrain so I installed a switch on the dash to disable the lockup solenoid. The extra lock-up sequence in 3rd gear was even more annoying as the 97 does not do this. This is not the "mystery switch" that forces a lockup and in fact is the opposite. The mystery switch is vey hard on the soft parts in the tranny when changing gears locked.
I had done this in my 97 2500 and all I had to do was put a simple switch in to open the circuit to the solenoid. Last week I tried the same thing in the 2000 but it immediately went into 3rd gear limp mode. New software in the 2000 PCM so I had to take a different tact. I finally ended up switching in a 150 ohm 5 Watt resistor connected to switched 12V with a relay to make the PCM think the solenoid was still connected. The relay is activated with a round rocker switch on the dash that looks factory. The relay has a 75 ohm coil but the higher the resistance that does the job the less current required. If anyone else is interested I can post the circuit diagram. I basically cut and spliced in the circuit in series with the OR/BK pin 11 on connector C2 (middle of the three) on the PCM. No codes get set with this circuit. The relay can be eliminated by using a STDP switch but its hard to find one that looks factory. The switch has to be 2 position only and not a 3 position or a code will be set saying there is an "open solenoid circuit". The hardware is mounted immediately beside the drivers side hood hinge on the small ledge inside a small electrical box with a 4 wire trailer connector.

This is my 1st post on this excellent site so I will fill in the signature once I figure out how. ]]> Reliablity / Performance balsip http://forum.mopar1973man.com/showthread.php/2142-47RE-Torque-Converter-Lockup-Disable-Switch
