Sorry for the bad news, but it sound like your Blazer has a intake manifold gasket failure. Your going to have to get that addressed soon as possible, the coolant is corrosive to the engines internal bearing and if left to mix with your oil to long will cause you to replace the whole engine rather then just the intake manifold.
When replacing the intake manifold gasket, use the upgraded gasket made of brass rather then the plastic ones that tend to fail. You can get the upgraded part at your local GM dealer or NAPA.
Thank you for using fixya and good luck.

Sounds like it could be a head gasket. Most shops will pressure test it (not expensive to test) to find out if that's the culprit. Pretty common overheating cause if you have a new radiator, thermostat and water pump.

95 Chevy caprice leaking antifreeze from what looks like a pipe under the engine.. But the serpentine belt is wet & spraying antifreeze, so wherever it's leaking from, it's hitting the serpentine belt


Your water pump has a small hole on the top and the bottom of the housing right behind the belt pulley. This is known as a weep hole and is there to let you know when the front seal has gone out of the pump and it is in need of changing. You really want to get this taken care of because on your engine the ignition system is ran off of the crank pulley and is known as "Opti-Spark" when the system gets antifreeze in it it usually goes bad. The Opti-Spark distributor sits right underneath the water pump, so a leaking water pump soon will take out your distributor which is another added expense.

Coolant leaks around water pump area ,does,nt over heat.


Your water pump has a weep hole that indicated it is starting to go bad. Look at the lower part of the water pump while engine is running just below and behind where is says (THREADED SHAFT) when engine is fully warmed up if water pump is going out there should be antifreeze in this area leaking down onto the crankshaft pulley. In RED is where to look for antifreeze.

    Place the drain pan under the radiator petcock. Open the petcock and allow the antifreeze to drain. If the drain pan is clean and the antifreeze is less than five years old, you can reuse the antifreeze.

    Place the block of wood on the floor jack. Slide the jack under the engine and raise the engine slightly. Unbolt and remove the front engine mount. On the 4A-GE engine, loosen the power steering and air conditioning belts by loosening the adjusting nuts or bolts on the slider bracket and sliding the accessory toward the engine. Remove the belts.

  • 3Loosen the water pump pulley bolts with the appropriate socket. Loosen the alternator locking bolt and the pivot nut. Push the alternator toward the engine to loosen the tension on the belt. Lift the belt off the pulleys.

  • 4

    Remove the four bolts on the water pump pulley using the appropriate socket. Remove the water pump pulley. Disconnect the water inlet and bypass hoses from the inlet pipe using a screwdriver or pliers, depending on the type of clamp used.

  • 5

    Disconnect the water inlet pipe by removing the two clamp bolts and the two nuts behind the pump. Remove the inlet pipe. Remove the O-ring from the back of the pump. Remove the mounting bolt on the oil dipstick tube. Remove the tube and the dipstick. Plug the hole with a rag so that debris doesn't get into the crankcase and contaminate the oil.

  • 6

    Remove the upper and middle timing belt covers. Remove the water pump retaining bolts and pull the pump off the engine. Take care not to get any antifreeze on the timing belt.

  • 7

    Place the O-ring in its groove on the block. Install the water pump and tighten the bolts to 11 ft.-lbs. of torque. Reinstall the timing belt covers. Make sure they are seated properly and not touching the timing belt.

  • 8

    Coat a new oil dipstick O-ring with engine oil. Slide it on the dipstick. Reinstall the dipstick and the retaining bolt. Tighten the bolt to 82 in.-lbs. of torque. Place a new O-ring on the inlet pipe for the water pump. Reinstall the inlet pipe. Attach the clamps and bolts that hold the pipe in place. Tighten the bolts to 8 ft.-lbs. of torque.

  • 9

    Reconnect the inlet and bypass hoses to the pipe. Install the water pump pulley. Tighten the four pulley bolts enough to hold everything in place. Reinstall all the accessory drive belts and adjust the tension properly. You should be able to turn the belts 90 degrees when they are at the correct tension. The water pump should resist turning. Tighten the water pump pulley bolts to 17 ft.-lbs. of torque. Reinstall the engine mount. Tighten the petcock on the radiator. Refill the radiator.

    I have a Kia Sephia 01. I had my engine over heat and warp almost everything. i've tried replacing the thermostat housing three times but everytime i refill the coolant and it runs through the housing it...


    Likely you are overtightening the housing. If you have paper gasket type, try using a double gasket. If "o" ring type, just use the gasket. When tightening the housing take up small amounts on both sides, alternating from one to the other. Tighten till it is firmly mounted but stop there. After filling system, check for leakage. if seepage is noted, take up on bolts one quarter turn or less till drip stops.always alternating from side to side. Unless you have the wrong thermostat in there this pretty much has to work.

    Antifreeze leak at lower raditor housing? antifreeze dripping down oilpan by dipstick tube and aircondition compressor only when hot.


    you may have a water pump that is starting to fail. Look for the water pump that's driven by the fan belt. look at the housing of the water pump there is a relief hole that they drill in the casting and when the pump begins to fail it will drip out this hole. If that's where your leak is, it's time to change the pump.
