Which engine?
Are you looking for a leak or does the engine just get hot?
It's been my experience that unless you have the timing too advanced (not probable on computerized engines), or there is a spun bearing (which would make noise), then an overheating problem is most likely (after the thermostat) the radiator being plugged up. It could have been partially defective to start with (no, 'flushing' doesn't usually help).
Bars leak will only make the problem worse.

SOURCE: My 1999 chevy tahoe is leaking antifreeze. I

it could but- check passenger side front where heater core line go into manifold right behind alternator the hose line is connected by a press clip into an alloy fitting this fitting gets eaten away by anti freeze and hose angle pulls back on fitting the part is $18 at dealer and is screwed into manifold use caution if ur r going to replace at very edge of aluminum manifold---and check ur water pump bolts the 2 longer ones should have a lock sealant on them they bolt in thru a water jacket

SOURCE: water leak under the intake manifold,1995 toyota 4 runner

There is a heater core bypass pipe that runs from the block (under the manifold) to the bacl of theengine where you will see a flat rectangular "sheet metal" thing with a pipe coming out of it. The a rubber hose connects. You need to pull the top air plenums and intake to get to it. The p[ipe flange bolts to the block with silicone rtv as a sealant.

Have you replaced the intake manifold gaskets? These engines have a history of leaking intake manifold gaskets. Water leaks into the intake and is burned off in the cylinders. If the engine overheats enough times, you will eventually blow the head gaskets.

Start by performing a compression check to make sure you haven't blown the head gaskets. Then make sure the car is really overheating (i.e. check the temperature of the engine with a infrared thermometer (they are cheap at Harbor Freight).

If it is really overheating, and you've really changed everything else, you need to change the intake manifold gaskets. Be sure to get the improved gaskets from the parts store (they have a metal core with rubber coating).

Tip

Intake Manifold gasket replacement and/or leaking= Ford


Intake Manifold gasket~

Replacing intake manifold gasket:
Replacing the intake manifold gasket, I used the tube kind, it's a make it youself for about $6 (it's blue and the consistancy of toothpaste) follow directions carefully! You can get a tube at Autozone or any car parts store. Has been working great. Just ask the cashier for the make it yourself kind of intake manifold gasket. Sorry, I don't remember the name of it, it's been that long...lol...

As for the Intake Manifold leaking coolant....It could, but shouldn't. One of the largest problems I've seen for coolant to leak out the Intake Manifold has been due to pressure in the system somewhere... Check the classic area:
Water pump- look for either water seapage and/or coolant. You'll know if it is because you will see real water either coming out of the water pump leak hole or under the thermostat. Most of the time coolant will pool where your heater hose runs in the intake manifold.

Mentioning heater hose. Check for leaks, holes, and/or cracked heater hoses. In-addition to the water pump, heater hoses...Check the transmission system, exhaust system, fuel system, radiator system, A/C system, secondary fan (located above the water pump housing), and thermostat.Also, check all electrical connections....Hummm....This is almost the entire workings of the vehicle.

NOTE: "It seems to be an infinity kinda thing... Once one thing starts to fail and is ignored, you are bound to be fixing a chain of event failures. Therefore, Do not ignore even the smallest problem or you'll be bound for life in repairs...."

Hello I have a 2000 Cadillac Deville if the intake manifold gasket is bad would that cause my car to overheat?


It can cause it to overheat if it is leaking coolant into the engine or outside of the engine. Replace your thermostat and check your oil for water and your antifreeze for oil. This will confirm if your head gasket or intake manifold gasket is leaking. Check you water pump for leaks and and make sure your coolant reservoir and radiator are full with antifreeze. Another possibility is your catalytic converter is plugged up

2000 chevy venture overheating and low coolant light on when coolant is full


There is a heat sensor located near the thermostat that goes directly into the block. Get a Haynes or Chiltons manual.

The thermostat is probably bad and causing your overheating. If that is not hte problem, then it would probably be your water pump.

Does any coolant flow through the intake manifold? I've replaced my radiator and thermostat an my car is still overheating. The heater core recently blew. I have a new water pump but not installed yet....


Yes coolant flows through the intake. Are you sure you didn't put the thermostat in upside down? That's about the only thing that can cause a rad or heater core to blow. It should be installed so the spring part goes into the block.

I have been having problems with my car leaking and overheating for some months now. I first replaced my thermostat, which worked for awhile. Then once the problem resumed, I changed my upper radiator...


I AM LOOKING AT THE RADIATOR CORE LEAKING OR ITS PLASTIC SIDE TANKS.CHECK WATER PUMP WEEP HOLE IT WILL LEAK OUT COOLANT WHEN PUMP GOES BAD IT WILL CAUSE OVERHEATING.CHECK THE CYLINDER BLOCK CORE PLUGS SOMETIMES THEY WILL GO BAD AND LEAK OUT COOLANT.
