How to replace freezeplug for a 2000 oldsmobile alero


Remove the old one and tap in the new one with a hammer and a socket that fits inside of it. Can you actually reach the leaking freeze plug without pulling the engine? Maybe try some leak sealer like Blue Devil instead and leave in the old freeze plug.

Idles@2500 rpm until engine warms up


old post
all do, everyone. but. the devil really is in the details with EFI.
this IAC valve does that,
to speed it up warm up , put in a 195F thermostat.
this assumes 800 RPM is hot.
most of these engines, do this. new. bewlow.

1: cold start, for 3 to 15sec, 2500 rpm , worse in alaska.
2: then the above DASH pot closes and IAC takes over, at ~1200
3: then as engine heats the IAC closed inch by micro inch a
its now 100% closed and the ECU not controls idle hot.
using the modulated ISC,
there is a fast idle feature on this year, 950 to1000 rpm hot
with these turned on.
1. headlights hot.
2: defrost glass, rear.
3: heater fan on.
4: a/c on if opted.
other wise 800 is normal hot.

Change thermostat 2003 impala


Follow the top radiator hose from the radiator to the engine. The housing that contains the thermostat is where the hose attaches. Make sure the engine is cold because you will lose some coolant. Remove the radiator hose. Remove the two bolts that hold on the thermostat housing. Remove housing. Do not remove the thermostat until you have the new one ready to put in and put it in exactly in the same direction as the old one. If you don`t it will not work properly. Re-assemble everything taking care not to over tighten the housing bolts. Top up the coolant and start the engine. Observe the coolant level until the engine is at operating temperature and check your coolant level. Top again if needed.

06 chevy.Impala running hot,i install a new radiator and fill with dexcol ilet run 30sec. later it run hot. how do i bleed the air out


DID you change out the Thermostate? the thermostate will open at around 180 degrees to cool off the motor if it fales to open it will make the car run hot. REPLACEMENT BELOW $40.oo range.

  • Open the hood of the impla and locate the thermostat housing. Find the largest hose at the top of your radiator, then follow it until it connects onto a portion of the Impala's engine block. The piece that to which the hose connects is the removable thermostat housing.

  • 2

    Use a jack to raise the Impala off the ground, then settle it down onto jack stands. Make sure the car is in park and the emergency brake is on.

  • 3

    Place a large container under the Impala's radiator. Drain the radiator into the bucket by loosening the clamp on the lower coolant hose with a flat-blade screwdriver, then removing the hose entirely so that the coolant flows into the bucket. Once the coolant stops flowing, set the bucket aside.

  • 4

    Use the screwdriver to loosen the clamp on the coolant hose connecting to the thermostat housing, then remove the hose from the housing completely. This will give you access to the bolts securing the housing to the Impala's engen block

  • 5

    Use a wrench or ratchet and sockets to remove the bolts securing the housing to the engine block, then set them aside somewhere where you will not lose them. Loosen and remove the thermostat housing to reveal the thermostat.

  • 6

    Make a careful note of how the thermostat is oriented toward the Impala's engine block. You must install the new thermostat in the exact same way as the old one is installed. Remove and discard the old thermostat.

  • 7

    Use a scraper tool or a razor blade to remove any remaining bits of thermostat gasket from the bottom of the thermostat housing and from the engine block. It is important to get all the remains off; otherwise the new gasket will not seal properly.

  • 8

    Apply a layer of gasket sealant to the bottom of the Impala's thermostat housing, then press the new gasket against the sealant so that it sticks and makes a good seal.

  • 9

    Install the new thermostat in the manner you noted in Step 6, then replace the thermostat housing and secure it down with the bolts. Reconnect the hoses you disconnected--making sure that the clamps are tightened down so no coolant leaks--and refill the Impala's radiator with the coolant you drained out earlier. Use your jack to lower the Impala back to the ground.

    Where is the thermostat on a 2005 impala 3.4 and how do I replace?


    Your thermostat is located inside the thermostat housing at the end of the upper radiator hose, on the back of the engine. Just find your upper radiator hose and follow it to the engine. It's hooked to the thermostat housing. easy... now comes the fun... To replace your thermostat, you have to remove the air intake duct (which mean unplug all your sensors on it, MAF etc). That should give you better access to the housing. You still have the throttle body right above the housing, and you may have to remove it too for better access and that sucks...(it involves disconnecting some coolant bypass lines...make sure you drain your radiator before you do so) Once you have that done remove the thermostat housing (after you unplug the coolant temperature sensor) and have some towels and a bucket ready as coolant will be coming out of it. Remove the old thermostat, remove the old gasket if necessary, and put the new thermostat with the new gasket in there (with the spring pointing toward the engine). Put some RTV sealant on the housing bolt it back on there, and put the throttle body back as well as the air duct and all the sensors. Refill your radiator, turn your engine on and check for leaks.

    Thermostat is overheating


    This is one of the easiest things you will ever fix on your own car. Buy the new thermostat, and make sure you find out if ou need a O ring or a gasket. If it has a gasket you need to buy some blue sylicone also. Once you have all the parts then locate the termostat, special note make sure you notice how it went in. Remove it, after removeing the housing unit that its held inl. Sometimes they have to be screwed out of its housing. Once out and remembering how it looked inside the housing unit then put the new one back the same way. Now if its a O ring then put the new O ring in place of the old one. If its a gasket CLEAN the old one completely off then put your blue sylicone on both sides of the gasket, one side at a time not at the same time. then put the housing unit back together and tighten it back up.

    You have just successfully changed your thermostat.
