My 1996 Cadillac fleetwood had a leacing radiator so I changed it and now it won't stop overheating any tips


Make sure that the thermostat is working properly. It is a good idea to change the thermostat when you change a radiator. How long does it take to overheat? You can leave the radiator cap off, start the car and wait for it to heat up and see if the fluid is pushed into the radiator. If not and the car overheats then you know that the thermostat is bad.

Temp gauge spikes to hot


Sounds like you have air in the coolant system.. did you bleed the system after you replaced all this?.. did you replace the thermostat? You might add a comment about why you replaced these things .. and how you know they were failing>

Usually, hoses pop off if the radiator/expansion tank cap is incorrect/broken. Find out if this "mechanic" changed the cap, if they did, get the old one back or get a replacement from the dealer. I have never gotten a dependable replacement from any parts stores. If they didn't change it, change it anyway and see what happens.

Over boiling problem while temperature guage remains normal.


Replace the thermostat. The Thermostat is not functioning correctly. It is closed = not allowing the radiator fluid to flow when the engine is cold. When the Thermostat reaches a certain temperature, it is suppose to open = allowing the radiator fluid to flow.
Your Thermostat is not opening, causing the engine fluid to reach boiling point. When this happens, the sheer pressure will 'blow' boiling radiator fluid out the radiator cap. The Radiator Cap is designed to do this if operating properly.
Change that Thermostat and the over boiling should disappear. And yes it is something you can do yourself without much problem.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!
Please include your engine size on any additional information or questions..Thanks,

Car is still heating up after flushing the radiator, checking all hoses and changing the radiator cap, havent changed the thermostat but the symptoms dont seem like it would be the thermostat unless it is...


One good way to tell if the thermostat is the issue is to carefully touch the lower radiator hose when the engine over heats. If the lower hose is cool there is no circulation through the radiator and the thermostat is the problem.
Unless there there is an obstruction in the hose blocking coolant flow.
Has the lower radiator hose been changed recently? Make sure there is a spring in the hose to prevent it from collapsing and restricting coolant flow.

Heating problem


If you changed the thermostat yourself and have noted that the lower radiator hose is cooler than the upper radiator hose, you may have installed the thermostat incorrectly or have purchased a faulty thermostat. A lower radiator hose that does not get hot (or as hot as the upper radiator hose) is a direct indication of a faulty thermostat. Please vote for this solution if you found this to be helpful.
