2004 Astro Operating Temp?

[Corsemoto]

What should these vans run at? Mine is at 210 all the time and will creep up with Max A/C and/or Rear A/C on in traffic, etc.

I have not been able to source a lower temp thermostat for the 2004 model year as I could for my '97 Safari. Do these use the same thermostat? I replace the thermostat last summer with a standard temp from Napa and it still operates at the same. Going to be flushing the coolant soon and would like a lower temp thermostat for the hot weather here if possible. Need to check my fan clutch as well...

210 on the dash is about right.
Just remember, it's an indicator on the dash, not a true guage. Whatever it reads is probably normal. Varying from that point indicates a problem.

And the a/c will make it run hotter, just because of the extra heat load. Just make sure the rad and condenser are clean!

Jet Performance offers a 180 degree thermostat.

Yeh - My 2004 z motor has been running like that for a few years. Seems to have started when the water pump was replaced. Not sure if that was related. It would jump one tick above 200 (digital dash) and stay there for about 5 mintes then drop back down. I changed the thermostat and then installed a supercooler radiator. It made no difference. Still did the same thing. I thought it was the guage or sender.

I just did the inake manifold gaskets. When I had it off I noticed that the passenger side of the block had a sludge build up yet the driver's side was perfectly clean. I suspect that may indicate a hot cylinder.

Recently it's been staying at 210. So I just put a 180 in it. That made a definate difference. So now It jumps between one tick below 200 back to 200 now. I got 175K on it so who knows how much life is lef in her ?

My 2003 seems to run at 100 Celsius all the time hot IMHO...my 97 and 98 run just above 40-60...I figured the rad was plugged or clutch fan were not working correctly so I swapped it them with the 98 and installed a new thermostat everything but water pump...still runs at 100 was thinking a lower temp thermostat as mentioned ..as I will be replacing the transmission soon (heat is not a transmissions friend) would love to see it run cooler any other suggestions?

Yes, start a new thread in Engines.

Wow, blast from the past!

Since then I've replaced fan clutch and with Jet Programmer plugged in, it shows temp is right around 200° or so even though the dash gauge reads higher so nothing to worry about.
