#47 of 66 1997 Ram 1500 Ext. cab 4x4 by marklynn Feb 16, 2009 (6:48 pm)
My new issue is with the water temp guage, the truck started this morning and the temp went straight to just below 260 , After I drove it a bit, the guage would surge back and forth between "normal" and just below 260 , I would not get heat at the 260 reading, but when it dropped I would get heat ??? I do not know where my thermostat is ???  My old issue is I can not get one of my sparkplugs out, all the rest changed out great, one just simply refuses to let the socket slip around it, and it is the same plug ? I wonder if the metal protection cyclinder around the plug has caused a problem ?  My brake lights and ABS light , and check engine light are all on, I lost brakes one day, and now they work fine, but the lights will not go out, I have disconnected the battery for a reset, but the lights come right back on with applied pressure to brakes ??  My trailer brake setup no longer works either, is there a fuse or something ??? It will activate the trailer brakes when I manually slide the lever over, but will not automatically do it ?
#48 of 66 1999 dodge Ram Overheating gages by brock17 Feb 20, 2009 (9:39 am)
I drove my 1999 dodge ram into town which is 20 min and everything was fine. I went into the store for 20 minutes and then came back out and turned on my truck and started driving and my check gages light came and my thermostat redlined! It had low rad fluid so i filled that and my oil along with everything else was good. when driving it home i had my heat on full and the thermostat would start to go down and the check gauges would shut off but then would jump right back up again! I have no clue whats going on and would welcome any sugestions

To add to it my truck wont start 5 hours later and it still says its redlining when you try to start it!
#50 of 66 heating issues by ryans33 Feb 21, 2009 (6:05 am)
95 ram 1500 v8 318 gas 130,000 Having a problem with the interior heat. It heats up for about 10 mins then while driving blows out cold. I also have noticed that when the heat does blow out i can not set the fan on high because the air will not be as hot compared to the medium setting. Last night i flushed the radiator for about 45 mins to an hr took about six sessions in that time. at first when i opened the drain plug nothing would come out so i had to shove a stick in the drain hole, that is when the rusty water oily junk came flowing. Now my girlfriend drove the truck to work this morning dont know if the flush helped but if it didnt what else can i do. Im thinking it cant be the heater core, not smelling antifreeze or seeing it on the floorboard plus the hose coming the firwall gets warm. Thermostat the truck is not overheating. Any ideas..
#51 of 66 04 Dodge Ram running hotter than should by cuttersrider May 27, 2009 (1:44 pm)
I have an 04 Ram 4.7 L 1500, the temp runs between the half way mark and the last mark before red, and if I turn the A/C on it runs hotter. If I turn the heat on it will bring the temp back down to the half way point. I have flushed and refilled the radiator and replaced the radiator cap.The fluid level in the resorvior has not moved since I flushed it. So in Florida this is not a good thing. 90 degrees and I have to run the heat. Can anyone guide me in a direction to fix this problem? I am thinking maybe thermostat.

Replying to: cuttersrider (May 27, 2009 1:44 pm) I had something like your problem happen to me. I have an '02 with the same engine. I ran my truck too far and blew the radiator out of it. The dealership replaced the radiator, thermostat and fan clutch. I've changed the antifreeze and thermostat since then, also. For some reason, when the outside air temp was in the below 32 degrees F. area, it wasn't heating. I finally had to "burp" the coolant system. I guess, it had a pocket of trapped air within the system? I removed the radiator cap, while it was cool, and started and ran the truck, while sitting still, for about a half hour. It seemed to solve the problem. The thermostat is located, where the large hose attaches to the lower part of the engine. I hope, this has helped? I'm not a mechanic. Good luck.

Replying to: jgreen76301 (May 31, 2009 6:48 am) Thank-you. I am attacking the thermostat Tuesday morning. In the mean time I am riding my motorcycle. I just fixed it.
#55 of 66 changing a water pump on a 2001 dodge 1500 ram by dokkie Jun 24, 2009 (10:46 pm)
Hi I am trying to change the water pump on my truck. does anyone have any tips on how to get the hose off of the back of the pump under the air conditioning unit, it seems like it is just about melted on to the back of the water pump?? Where does this hose go to and how far back does it go? if i had to change this hose how would i go about it? I have got all other hoses, bolts and fan off this is the only thing holding me up any help would be appreciated. oh and i have a haynes book that i have read cover to cover with no help about this hose. i have read all over the net and this hose is called the by pass hose but no one seems to have any tips on how to get the darn thing off ! !
