#6 of 66 Coolant light comes on when AC on by caddynuts Apr 22, 2006 (10:19 am)
I have a 1985 Caddy Fleetwood Brougham. It has a HT 4100 aluminum engine. When driving in town the ac works, but on long road trips, the coolant light eventually turns on. AC has to be turned off to avoid overheating, then extremely hot air starts to come out of all vents including the defrost vents. I replaced the water pump, thermostat, belts & hoses, & air conditioner compressor last year. The problems started after this. I recently replaced the heater control valve, but problem persisted. All suggestions would be greatly appreciated. Replies to this message: Mr_Shiftright (Apr 22, 2006 11:37 am) worklerbately (Aug 27, 2006 6:11 pm)

These can be flow-tested by a radiator shop.   If that checks out, have the cooling system pressure tested for a head gasket leak, would be my advice.

My bf drives a clean 89 fleetwood but it's over heating. Water and coolant dry out fast.   HELP! Replies to this message: Mr_Shiftright (May 20, 2006 10:25 am) 1rubyd (May 23, 2006 5:57 am) Mr_Shiftright (May 23, 2006 9:56 am)

Replying to: queenfee (May 19, 2006 7:33 pm) Overheating can be caused by a whole lotta things. No guessing allowed. It has to be diagnosed step by step, from the obvious (is the cooling fan working? Is there a big leak somewhere?) to the somewhat less obvious (thermostat stuck? Air block in system? Clogged radiator?) to the less-less obvious (worn impellers in water pump? dragging brakes? underinflated tires?) to the most mysterious and dreadful (bad head gasket, cracked cylinder head).   Tests include pressurizing the cooling system to test for leaks and bad head gaskets, testing the coolant for combustion gases, having the radiator flow tested, testing the thermostat by removing it, and of course observing the operation of the cooling fan.

Replying to: Mr_Shiftright (May 20, 2006 10:25 am) From what I was told from the Cadillac dealer, he said that he did a "pressure" test. He said that was the way they could find out were the leak is coming from. What do you think? Replies to this message: Mr_Shiftright (May 23, 2006 9:56 am)

Replying to: 1rubyd (May 23, 2006 5:57 am) I think they didn't continue the diagnostic. You don't just do one test and then stop and shrug your shoulders...GEEZ...some of these dealers....
#12 of 66 Trouble with interior lights by bracey52 Jul 29, 2006 (8:49 pm)
I have a 94 Fleetwood(RWD). The interior lights stay on too long when i open the doors. When I close the doors the lights come back on. It takes about 15 minutes for the lights to go out. what can i do? Is there anyone out there that can help me?
#13 of 66 Tempermental Starter by ginamg Aug 18, 2006 (9:24 am)
Purchased my one owner 1985 Cadillac Fleetwood last year (2005). Has 106,000 miles. Runs and handles great when it starts. Sometimes after trying, I'll give the keys to someone else and it will start right up. When I called for it to be towed, it started for the driver and the repair shop said it would "never not start". It started regularly for a while and now it is acting up again. I've gotten it to start after it balks and after I've got it running it hasn't stranded me anywhere. Sounds strong. Is there any test for this? Thoughts, anyone!!?? Thanks
