#71 of 101 No heat - 2000 venture
Jan 20, 2010 (4:53 pm)
I have no heat coming from 2000 chevy venture. Sometimes I can feel a faint amount of barely warm air coming out with the fan on low. Any ideas what could be wrong?
I have put a gallon of antifreeze in the reservoir tank over the last 2 weeks. It seemed to help give me a little heat when I filled it to the cool level line, but not now. There are no visible signs of a leak and I don't see any antifreeze on the oil dipstick. The car is not overheating, but the temperature gauge is dancing around a little bit. Just out of curiosity, where is the coolant level sensor? Because I don't know if it's just another sensor in a long line of bad ones that just stays on now forever. Or the coolant really is low. I keep adding it to the reservoir tank so it's going somewhere.
Thanks for any help.

The level sensor is in the radiator. If you have to keep adding coolant and do not see any leaks you probably are burning it due to a bad intake gasket. If the system has air in it and not coolant you will be lacking heat. Easy way to see if coolant is seeping into engine look under oil cap for a yellowish goo and/or pull PCV value and see if you see the same. If you do you have an intake gasket failure.

Thanks. Yeah it had the goo just as you described. I'm taking it to my mechanic on Saturday for confirmation and an estimate. What a shame with this car. First the intake manifold gasket goes, and now most likely the head gasket. It would be OK if these gaskets weren't so costly to replace. But the costs are outrageous, and it's all for freakin' GASKETS! Add all the other failures of this car and it spells bye bye for GM for me in the future.
#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
#76 of 101 2001 venture temp sensor
Jun 13, 2010 (1:54 pm)
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.
