I am the original owner of a '99 'bu LS with 60K miles. Have been generally satisfied with the my car with the primarily problems: warped rotors (replaced under warranty), intake manifold gasket work, and alternator replacement. Oh, and the A/C control problem often noted on this board. Here's my current problem: I just recently had my radiator flushed. To be honest, I went over the 5 year limit by two years. My local Chevy dealer did the flush. Now 4 weeks later, the car is consistantly running hot (the temp needle crosses the half way mark - which is has never done before) and I have had to add coolant several times - once the light indicator for adding coolant came on. Thoughts on possible problems or other indicators I need to look at???? I had the much noted intake manifold gasket work done several years ago and there is no evidence of antifreeze in the oil but am not sure if this is the only indicator of this problem. Thank you in advance for any advice!! Magnus |

Replying to: mjohns7861 (Nov 29, 2006 4:49 pm) also put your heater on full blast set to high, see if it smells of coolant, that would be a bad heater core. Keep your eye closely on the dip stick and check the radatior for any signs of contaimination. How many miles on the engine?? Most water pumps fail around the 90-125K range. Hope this helps..

Car Profile: I am the original owner of a 99 Malibu LS with 59K miles. Reported coolant leak in thread above. Took into my dealership this week and said they conducted a pressure test and discovered a leaking intake manifold!! I had this *same* repair done at 36K miles over 2 years ago at a local garage in my town!! My dealership quoted me $750 to fix it. I declined the service at my dealership and have made my appointment with the local garage who did the work two years ago for them to take a look at it this Tuesday. A quick Google search tells me this problem can be reoccuring in the Malibu. If anyone has any thoughts or questions I should ask my garage let me know. Also, I am a bit paranoid given the age of my car and mileage if one should be "proactive" and get the water pump replaced now. Any thoughts on this are welcome. Thank you in advance, Magnus |

Replying to: mjohns7861 (Dec 09, 2006 5:06 am) a newer designs gasket has been developed by Fel-pro that solves the problem. As for the water pump I've never seen one last past 125K. In most FWD OHC engines a lot of people would have it changed with the timeing belt since the water pump ran off the timeing belt and you allready had access to it. I haven't worked on the 3.1 V6 (mine is a '05 3.5) so I can't say if it's the same situation or not, the 3.1 and the 3.5 are pushrod engines and dont have a timeing belt. Maybe someone who has worked on one could be of more advise here...
