overheating and fans not coming on

Asked by Jan 04, 2014 at 05:59 PM about the 2003 Chevrolet Venture

Question type: Maintenance & Repair

My 2003 Chevy Venture began overheating and I replaced the relays
because fan wasn't coming on. Now it continues to over heat. I can feel a
pulsing in the hoses and it takes a while to get hot so I think the thermostat
is fine. Could something like this be air or temperature sending sensor?

Is there a fuse connected to the fan? if so, check that first. Can you bypass the thermostat and see if the fan itself will run? If it does and the fuse if there is one, is good, the thermostat may be the problem. That is a common problem, especially in the lesser style electric radiator fans. That is why I bypassed my thermostat and put an inline fuse in. the fan runs all the time, but in a hot climate that is OK.

Computer chip under the passenger side glove box, $500.00 new. Told it should turn on the fans automatically, haven't tried it yet myself. I need to turn on the heat full blast in a drive through or my engine will blow up !!!

Check for air in the system a far as it overheating the problem is air goes to the highest point in the system and the bleeders are below that .I put in a prestone filler in the hoses that go to the rear heater and I hook the hose up to it on a trickle I have emptied and filled my radiator with straight antifreeze I start filling the system until there is no air coming out of the bleeders and then i start the car you must have good heat in the front and rear heaters for it to be full otherwise it will get air locked also check your temperature switch

I think chevy designed the electric fans to come on at 230 way to hot i used to run my ac and fans would come on you got 2 30 amp fuses and 3 relays and a temp sensor under thottle cAble but they had a problem with dexcool eating intake gasket i flushed that out and put prestone mix with any kind but as far as air you have a bleeder valve above water pump open that up when running to bleeder air then do the same with bleeder valve by themastat

    Both fans coming on, just replaced thermostat but when we get to the approx 2-3 mile mark it starts to overheat. Could it be air or ECU? This is also a wheelchair accessible van.
