your van won't get hot when you're cruising. the astro has a big intake for the rad. it will get hot when you put your foot down, but just criusing at highway speeds the electric fan shouldn't come on. i ran my van for a while with no fan, it was fine till i stopped. then it would get hot. all of my cars with electric fans never come on while cruising

rusty check your t-stat, some will get stuck open when they fail meaning the coolant is always gonna be circulating therefore preventing it from really getting hot, quickest way to check is to turn your heater on in the morning when is cold, if you can feel little to no heat then the t-stat is bad since when it warms up it should BLAST hot air out the vents.. just my two cents since that is what happened to mine

hello : I all ready did the t stat no change it runs under 160 * . not good for mpg heat is so so. goes up to temp fine sitin still fan on at 190*off at 180* just right start moving dropes to just under 160*..I put a valve in the heater return hose to restrict flow some no change .taped up lower part of rad. little change . should the water move as fast cold as hot .remove cap look in watch flow from heater return , warms up gauge {mechanicical gauge } 180* hot no change in flow looking in cap.should itry to put the lower fan shroud back on around the elec. fan ? Icoud cover more rad. but I do not like this idea .

Rusty,

I am not sure how I missed this Thread. Let me tell you what I found and did about it.

Rewind to Sept of 09. I flushed and changed my coolant in prep for a long trip. I did not change the Thermostat. I used Prestone mixed to 50/50. All seemed normal.
From the end of September through December (as it got colder). I noticed that the Coolant Gauge on the dash would not get up to 195.
Heater output was not at all hot either. Well I continued to monitor it, I also read all the tales of No Heat here on the Forum. I tried cardboard in front of the radiator also.
I decided to replace the Thermostat on January 7th. I used a Stant Super Stat 195 degree thermostat. I have since monitored its performance, and have not been disappointed.
It provides a much quicker warm up, and even in heavy stop and go traffic, never allowed my van to overheat. (the fan works good)
Now I can have the heater blower on high, temp set to hot, and have more interior heat than I can deal with.
Temps now hoover at the 195 mark, summer or winter, 5mph or 80 mph.

If I were you I would Replace the thermostat, 195 Stant Super Stat, and Adjust my fans cut in to 200, and cut out to 195.

I hope others will weigh in on the fan cut in and out temps.

Hope this helps, Jim
