Yeah I should flush the system out, but have no where to go with old coolant. Will need to take it somewhere for that.
In the mean time I got a 195 degree t-stat in, and the new 14 inch flex-a-lite flex fan on. Had to remove water pump to get it on. No room between rad to get bolts in and trying to line bolt hole up was impossible. Added a bottle of Water Wetter also. Started her up and car idled at 200. At first, as car warmed it went up to 220, then the stat opened and it went down to 200. Took car for short drive of about 15 minutes and it stayed at 200, but went up to about 205 at a couple of stop signs. Its was a mild day, cool and windy so I guess that helped keep it cool too. Suppost to be warmer tomorrow, so will try longer drive to see what happens.
I'm wondering should I try the 180 t-stat? I'd really like it to run at 190, but can live with 200, it will stay there and not go much higher. Summer will be the test.
