Hello, This is my first time porting on this forum. I just bought a 95 Cadillac DeVille, and I drove it home. When I got home, and I stopped the engine, coolant started to boil out of the coolant tank. No warning lights came on during the trip, and did not get any warning messages from the instrument cluster. Any ideeas? I'm not sure if the engine overheated because did not get any warning lights or messages. Any help is greatly appreciated.

Perhaps the coolant level was way down when you bought the vehicle. What you'll have to do is fill up the coolant and pressure test the system for leaks. If you have no leaks, then you look to other sources for overheating, which are many. On a ten year old car, the radiator is always suspect, as might be a stuck thermostat or an inoperative electric cooling fan. If these prove okay you might consider less likely candidates, like a broken impeller inside the water pump or a bad head gasket. |

Overheating! thermostat has been removed,new pump and hoses everything virtually new and in working order. the previous owner may have done some strange re-configuration hose routing at the heater-exspantion tank area(by-pass and pump inlet hoses) there's no leaking. this is the one with NO radiator cap! It fills at the exspantion tank. Helpful answers Please. Bigbyrd to hot to fly

Hi, after driving my 97 grand am for approx. 20 minutes I parked the car and immediately notice smoke (steam) coming from the top of the dashboard. At this time the fan was still running, and i heard a loud gushing sound, when I went got out of the car I noticed steam coming from under the hood and a large amount of coolant on under the car beneath the coolant reserve. I had someone look at it and they said they were unable to locate where the leak came from, but they thought it was from a hose connected to the engine. When I poured water in the reserve tank to see if I could drive it to a shop the water came right out. I had just replaced the radiator with a used one couple of days prior to this. Please give me an idea of what you think the problem might be, and how much you think it will cost to fix. Any help/suggestions you might have would be greatly appreciated

Replying to: plshelp1 (Jul 06, 2005 8:03 am) Best thing you can do is have the system pressure tested for leakage, and have the used radiator flow-testing for clogging. Also you can have the thermostat checked. I'm not sure if your car requires a special technique for adding coolant (bleeding air from the system as you fill). You might check into this and if you didn't do that, you can get overheating by having air trapped in the circulatory system. |

Replying to: Mr_Shiftright (Jul 06, 2005 9:03 am) I should correct myself, the total time it took to get to my destination was 20 minutes. The temperature gauge did not go past mid-point, and while driving there was no indication that there was a problem. The car just started to let off steam/smoke when I parked it and I noticed the pool of coolant underneath the car beside the right front tire. Is there a hose that is connected from the coolant system to the engine (towards the back of the car)? Because it was suggested that a hose might have burst or that there is a hole in a hose that is connected to the engine.
