99 Oldsmobile Intrigue, water pump recently replaced, and now temperature seems high?

I recently got the water pump replaced on a 99 Oldsmobile Intrigue GL (3.5L V6), and ever since the temperature gage seems to be running higher...between half way and the 3rd line, where before it was replaced it never got above the second line. It is doing this when I slow down and stop at lights. Once I get going the temperature does drop. Is this normal, or did they do something wrong?

    There's a few different things that could be causing your problem.

    1: Did they change the thermostat? If so, they may have replaced it with a defective one. If not, then it may need to be replaced.

    2: What was the reason the water pump was replaced in the first place? if it was for any other reason than leaking then this could be causing your problem.

    3: They might not have gotten all the air out of the system. when you drain all the water and then fill system back up, there are large air pockets in engine that must be bleed out. If not, these air pockets will get trapped behind the thermostat and cause the thermostat not to open when it's suppose to!

    4: Are your cooling fans coming on? If not, you may have a bad temp sensor, causing your fans not to come on while you are stopped.

    This type of problem is hard to narrow with out seeing it in person. I would take it back to the place that replace your water pump and see if they can figure it out.

    the main important undertaking is that that's a 'ninety 9 Olds Intrigue. whilst a motor overheats, various issues can take place... none of them reliable. basically when you consider which you notice no water interior the oil does not advise you haven't any longer have been given a cracked head. you additionally could have oil on your water, or water interior the exaust... relies upon on the place the crack is. I basically had an analogous oil loss undertaking ensuing in a destroyed crank bearing. in case you haven't any longer have been given a reliable mechanic interior the family individuals (or in mattress with you once you awaken interior the morning) you're extra powerful off scraping the automobile. that's distinctly much valueless as a commerce in, and the thousand/s you will could desire to place into it just to get it back to being a 'ninety 9 Olds could be extra powerful spent as a down on a clean/er vehicle. Sorry, yet i've got been twisting wrenches for 30 years and the likelyhood that it may be so user-friendly as including water and oil is approximately as reliable as you triumphing the lottery. If it have been basically a head gasket, you're nonetheless staring at over $one thousand, except you're a mechanic.

    If you had it done at a shop take it back. Alot things can make a car run hotter. Could be as simple as an air pocket in the cooling system or a leaking head/intake gasket. Did you over heat the engine when the water pump went out? If so the temp sending unit could be bad.

    It means the fan isn't working. No air is going through the radiator at low speeds.

    Did you replace the thermostat? flush the radiator also. If your pump is not leaking it should be good to go.
