    i have a over heating problem, well i live in south texas and didnt have any problems with it this past winter but as soon as weather started getting warmer the temperature gauge really moves over to the right, dont want to mess up my engine.

    do i just change out thermostat and flush radiator, and just let it ride or has anyone had this problem before?

    please help!!!!:frustration:

    Is your rad fan coming on?.if not then that would be the problem....possible air lock in the cooling system, I wouldn't blame the thermostat just yet until you check the other possibilities

    temperature gauge may also be bad.

    check your fan if it works. then i would buy a aftermarket temperature gauge then see

    Agree with Fupa... could be an air bubble in the system. Some of the lines are small! Easiest way to bleed it is to raise the front end 6 or so inches and then un cap your COOL radiator, then start and run your truck with the heater on high. Might also have had some crud break loose from somewhere and clogged a line. But if it turns out to be your thermostat, do a search for some of the other threads on here that explain the drilling of a hole in your new one. Good luck, hope this helps, and keep us updated!:pop:

    I'm in SE Texas and know your problem! The heat here can do a lot of damage to a cooling system, but think of it just like a car or truck with an electric fan.

    The first thing to check is the electrical connection from the radiator to the fan. I've had one where the connector broke. In the brush of a Texas lease this can easily happen. BTW, a small piece of sheet metal and some self tapping screws does a great job as a shield for this problem.

    Next, always check the antifreeze level. Whenever it's a low the electric fan will not run. I have no idea why this happens, but I've seen this also.

    Third, connect a battery directly to the fan. If it doesn't, there's your problem. If it does, check to see if you have current at connection at the fan.

    If all of this is good, then go to the thermostat.

    thanks guys, i do hear my fan come on periodically, i will take a look at it tonight and see if i can solve this problem, i do notice that the temp does go down when i turn the heater on high, that helps, but not when its a 90 plus outside!

    thanks again!

    Does the temp drop when you the fan comes on? If not, I'm guessing your antifreeze level is really low.

    Turning the heat on drops the temp because it pulls the heat from the engine to you! No fun in Texas :D

    yeah i had it worked on last summer on some carb problems that i was having and had the mech check out the cooling system and he said that everything is fine,

    i guess i am going to have to solve it myself. also thinking about wiring the fan to come on all the time, since its so hot down here.

    I thought about doing this since I'm also in Texas, but once I figured out about the broken connector and low fluid level I've not had a problem.

    Let us know what you find out.

    If the fan is only coming on once in a while there must be a problem with the sensor(temp switch) possibly the wiring is corroded and only making occasional contact...I would bet the fan switch sensor is covered in rad slime and isn't getting a proper temp reading,or the fluid level is low as Kego stated....try a rad flush and refill making sure the bleeding/refill is done properly to remove air...your temps in Texas shouldn't bother your truck..the climate they were built for is just as warm in places much of the year..
