#74 of 101 Overheating problems
Apr 07, 2010 (6:10 pm)
My 2003 Chevy Venture Van is overheating. What's happening is anti-freeze is coming out of the overflow, when heating up the radiator hoses become stiff from possible pressure, fan is not coming on in time to cool the motor, but if I jump them it still overheat.
My heater stopped working about 1 month ago at a stand still, but at high speed it begins to kick out heat. The temp gauge goes down at higher speeds, but at lower speed temp rises. could this be related to the problem?
Replaced the thermostat and the water pump. Help please! Could it be anything else except a busted head gasket?

Did you burp it after you did water pump & stat?
If you didn't that;s a simple fix. there is an air bleed screw and maybe two of them? Located toward the top of intake area .. As you turn the small hex of the bleed screw open (counter clock wise) air will come out and when it's solid collant shut it off... I did this years ago there may be 2 burp valves ? look in owners manuals it may be in there ? otherwise go to service manual or go to Library for ALLDATA ask refercne librarian if you never used it.
Are you USING any collant ?,,,gotta pay attention to this one. and keep an eye on it overflow bottle if hook up propelry is a good way maybe once check rad to see if it's full.
are you loosing collant externally ? leaks on floor or possibly leaks and burns off with engine heat/Exhaust you would smeel it very likely if this was the case
Caps are pretty much the same as a lot of cars swap caps if they are the same don't force it if it don't fit.
as you know everytime you open up rad cap you will loose a little collant(( normal.)
Do you have access to a rad pressure tester ? if so on a cool engine hook it up to rad and run engine like normal, if pressure builds over 20 psi and keep building you likly have a head gasket gone.
oTHERWISE IF YOU REPALCE PLUGS AND SEE GREENISH TINT ON ONE IT COULD BE COLLANT GOING INTO CYLINDER.
Collant could get in the oiland cause it to turn milky
collant can also go into the exaust and usually it will make smoke or sweet smell depends on how bad it's leaking..
Other wise a ch

I change radiator last October and everything works fine except recently fans come on way past the gauge mid (12 o’clock) position. I want them to switch the fans earlier than that.
There should be no sludge (there was no sludge back when I was changing the rad, oil is clean, coolant level does not go down.
I cleaned all the fun relays and connectors, no difference.
I tried to run engine with sensor unplugged, temp gauge showed no temp reading at that time. When plugged back, temp was shown on the gauge.
Can anyone tell me if the temp sensor (located beside the thermostat) is an on/off sensor or it actually gives the range signal to power temp gauge on the dashboard? If range, what is the range suppose to be? There is no air in the system.

I am replying to my own message above – this is pretty dead forum!
I changed the fan switching sensor (located near the thermostat). This is an on/off sensor switch.
Fans come on at the same temperature as with the old sensor – about 2 o’clock on the dial. What else can cause this high switching?
anybody? thanks in advance.
#78 of 101 2000 Chevy Venture Front A/C blows cold--rear A/C blows hot
Jun 21, 2010 (4:38 pm)
I have a 2000 Chevy venture that has a problem with the front blower putting out cold A/C and the rear blows out hot air. I already have the trim panels removed and can see the blower assembly but need further help from there to figure out what is going on. please help.

Venture Thermostat replacement I just checked this link and it is still good. It looks like it should help since it has instructions and some diagrams. I know this is for a different year, but I doubt the thermostat has been moved.

I own a 2003 chevy venture and I am having trouble with the fan. When I have the settings set on vent and the heat turned to max and the fan to number 5 setting very little air flow comes out of the vents. As I turn the heat control to the cool setting the air flow increases. Max. air flow is when heat control is set to max. cool setting. Why?

I am actually having the same issue with our van as well.
You can hear that it is switching from cold to hot, and when you put your hand on the vent you can barely feel the hot air coming out. I then turn the temp to cold and you can hear it switch and it flows out pretty good...(almost too good).
