Stoney Lawson Posted August 5, 2013 Report Share Posted August 5, 2013 I just bought a 2000 deville 130k miles She came to me overheating (I traded a 95 Camaro that I paid 800 for), the water pump was froze and the seals were busted there was no water, he said he came out one morning, and there was no water, he turned it on, got hot, turned it off and then I paid for it to be towed to my house. She is NOT overheating now after I did the water pump and all new gaskets and hoses. My question is, this morning I was driving between 10 - 20 mph for about 10 minutes, and the temp went one notch over half, not anymore and then went back down, is this normal? This is my first cadillac, or northstar motor, so I don't know the operating temps based on the digital meter. Link to comment Share on other sites More sharing options...
KHE Posted August 5, 2013 Report Share Posted August 5, 2013 I don't think I'd worry about one notch over the half way point. If it begins to overheat, then there are some things to check.

Stoney Lawson Posted August 5, 2013 Author Report Share Posted August 5, 2013 I've tested for blown HG, and exhaust/fuel in oil, it all checks out great, so maybe the system hadn't have been bled all the way of the air and there's still a pocket of air moving around Link to comment Share on other sites More sharing options...
Texas Jim Posted August 5, 2013 Report Share Posted August 5, 2013 Check the purge line going from the water pump to the plastic coolant tank. Make sure it is flowing coolant when the engine is cold. Link to comment Share on other sites More sharing options...
Stoney Lawson Posted August 5, 2013 Author Report Share Posted August 5, 2013 I didn't even think that hose! Link to comment Share on other sites More sharing options...
Texas Jim Posted August 5, 2013 Report Share Posted August 5, 2013 I didn't even think that hose! If it is not flowing ... air CAN NOT get out of the system.... Link to comment Share on other sites More sharing options...
Cadillac Jim Posted August 5, 2013 Report Share Posted August 5, 2013 The system doesn't keep air trapped unless the bypass is clogged. Either Logan or I can find you a diagram from the FSM if you can't find it. Start at the surge tank, and look for a small rubber hose that goes into it near the top. The hose at the bottom of the surge tank is large and is the drain into the heater hoses. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

Stoney Lawson Posted August 16, 2013 Author Report Share Posted August 16, 2013 Figured it out, was low on coolant, from when I first put coolant in after the water pump repair. Is the fuel level sensor, apart of the fuel pump? Link to comment Share on other sites More sharing options...
Cadillac Jim Posted August 17, 2013 Report Share Posted August 17, 2013 The fuel level sensor and the fuel pump are part of the in-tank assembly. I believe that they can be changed separately. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
