Question about 1998 Chevrolet Malibu

Water pump and thermostat needs replacing on my 98 malibu, $1000?

The mechanic has giving me a $1004 estimate to replace my leaking water pump, thermostat, and timing chain. Is this reasonable?  Could I replace the water pump and timing chain myself?  From my research the parts are no more than $125 total. So, $875 in labour? Really?

    I brought my 2000 Malibu (66,000 miles) to my mechanic a few weeks ago to replace the unibelt, which he did for about $150. A rattling noise and non-functioning heater was undiagnosed until I brought it back yesterday. My guys decided there was a problem with the water pump and then they diagnosed a losse tension thing that was causing the noise. The water pump and thermostat cost about $350 to replace at this gas station/service station in New York City. Another local mechanic confirmed the estimate.

Yes, you can change it yourself and yes that is a reasonable estimate on the labor.

That being said, let me explain. The timing chain is a very important part. It controls the timing of the intake and exhaust valves opening and closing at the right time in relation to the pistons moving up and down in the cylinders. If you make a very small mistake in changing the timing chain, you will cause major engine damage. On top of that, it is not very easy to get to in the first place.

I would recommend getting a second opinion from another dealership, but if you are asking this question then I would recommend having a professional do the work. It is likely to be less expensive in the long run.

Bad water leak probably heater coil


Sometimes, not the heater coil...this leak usually smells inside the cabin...can you see anti-freeze build up anywhere? These motors are more prone to a water pump leak (needs replaced, inexpensive and not to difficult) or the intake manifold gasket...more costly about $400. for a mechanic to do...you should see some anti-freeze build up around the intake bolts...this assumes that there is no water in your oil...which is far more costly as this indicates an internal cylinder head leak...Could be just a hose leak...a bad radiator cap...or thermostat housing leak, (maybe a cracked housing? Help me help you...do you see any anti-freeze build up anywhere? Hope this helps.

My 1999 Alero must have a leak somewhere because the thermostat gauge rises every few days. I put coolant in it at least 1 a week. I had a new water pump and thermostat put on it, but it is still...


CHECK AROUND WATER PUMP AREA.AND THERMOSTAT HOUSING FOR LEAKS.THE MECHANIC WHO PUT THE WATER PUMP ON MAY FORGOT TO PUT SEALANT ON BOTH SIDES OF THE WATER PUMP GASKET CAUSING LEAKS.LOOK AROUND THERMOSTAT HOUSING FOR LEAKING.IF THERMOSTAT SEAL WAS DAMAGE DURING INSTALLATION IT WILL CAUSE LEAKING.IF ALL LOOKS GOOD CHECK FOR COOLANT LEAKS AROUND RADIATOR .CHECK RADIATOR TOP AND BOTTOM HOSES FOR LEAKS AND CHECK HEATER PIPES AND HEATER CORES HOSES FOR LEAKS.IF ALL HOSES GOOD.CHECK FOR LEAKING CORE PLUGS.

My 98 chrysler cirrus is lesking water and im told


First open the hood of your car and check where the leak is coming. Thermostat gasket is one source but
it could also come the radiator, radiator hose, or the
water pump. Check all these items, and you can do
the repairs by replacing the defective parts. Except for
water pump that really needs a mechanic to replace the
bearings and the mechanical shaft seal.

Coolent is leaking from overflow and overheating


I will agree with your uncle and say that you should check the water pump. Start the vehicle and look at the water pump. Most water pumps have a "weep hole". If there is coolant coming out of this hole the water pump is not working properly. If not, and if the temperature has been running normally, you may have fixed the problem when you replaced the cap, if the water pump is good and the temp has been running high, then check the thermostat. Hope this helps and good luck.

1998 plymouth voyager3.3l has leak at water pump behind pulley


First of all, changing thermostat will not fix your water pump leak. Obviously defective pump or install. Be sure to take a closer look, in case it's a loose hose in the area. Leaking from behind pulley, usually calls for new pump. What I would do though, is take it back to original repair shop & question them about any warranty that may apply. Some have 1 yr. some have limited lifetime etc. If you can obtain a copy of work done, the part number on the pump should give you what you need to call (or shop can call) and inquire about that particular part number as far as warranty goes. (I'd make the call myself, ahead of time, so I know.) That way, perhaps the shop who originally installed it may feel some kind of obligation to replace it at a reduced fee, as in labor only. ($27 for new pump) . Be nice, play a little dumb, it may help, and if they want you to pay the whole shot over again, go elsewhere for estimate.
