#8 of 9 2000 Chevy Impala losing coolant
Oct 08, 2012 (6:40 am)
I have a 2000 Chevy Impala that has an overheating problem. I have replaced the radiator fan assembly, the radiator was cracked so I had to replace that, and I also replaced the coolant sensor. My car is still loosing coolant. When coolant is in the system, the heat gauge will go a little past the halfway mark and then go back down. It fluctuates like this unless there is no coolant in the system, or unless I am going at a high speed (60-70 mph), then it will simply overheat. Two people have told me that it is the head gasket, however it shows no visible signs of being the head gasket. No white smoke coming from the tail pipe, no milky substance in the oil, etc. Two other people suggested that it is a pinhole. I am trying to avoid paying $1500-2000 for a head gasket if that is not the problem. Any suggestions/ideas???

Mu '05 lights will flicker some,not bad but i have heard it's an alternator issue or a wiring issue with the alternator,that's what i heard.I think there is a TSB on that.(technical service bulletin),search for your car and it's year online with T.S.B. and see what you find.
Gas needle moving could be a loose fuel pump float or bad fuel sensor in the tank.I have a sloshing noise in my tank and i know it's more of a poorly designed gas tank baffle system,it doesn't bother me to much.
If you have age and alot of miles on it you may wish to just change the fuel pump out and make sure you get one with a float on it.i've seen some that don't have it on them and those are the real cheap rebuilt ones.Me...i'd get a new one and be done with it for years to come.
Check engine light has stored a code in the computer,have someone scan it for the error cose(s) to see what's going bad or is bad before it get's worse.Many shops will do a scan for free if they get the repair.
Best of luck to ya.
