Best bet is the gasket. After removing the head have it serviced professionally, replace thermostat and water pump and timing belt while in there

My thought is that you probably have a blown head gasket or a cracked block. I would have someone do a pressure test on the coolant system to determine where the leak is. Doesn't sound good.

This sounds like a water pump leaking. Get a mirror and see if you can see the place where the leak is coming from. On the water pump is a small hole, this hole is called a "weep hole". it is there to warn that the water pump is getting worn and may fail soon. Anti-freeze, once it leaks on to the engine and gets warm enough to dehydrate then gets some road dirt stuck to it, it does looks a lot like oil and feels a lot like oil. I think your are looking at a coolant leak coming from your water pump. A shop can pressure test the coolant system and find out if it is the water pump or a head gasket. Hope this helps FixYa up.

Most likely a frost plug, you may need a mirror to see it.
The head is not likely to just leak from the back, check for steam from the exhaust when hot.

My 02 gmc truck will overheat when pulling a load or excessive idleing. 6.0 motor. Replace thermostat, fan clutch, water pump, flushed and blew out radiator. Still will overheat??


I would run a cylinder leak tester. It sounds to be a cylinder head gasket leak. I assume there is no oil in the anti freeze, or anti freeze in the oil? They sell these "combustion leak tester" on ebay for around $30. easy to use. If this is not problem then you will almost certainly need a new radiator

Head gasket was leaking on my 86 mr2 Replaced the


Check all the wiring connections that you loosened or took off when you removed the head. something is loose or disconnected ,eg., ground wires .
Make sure you have spark at spark plugs whemn cranking ,and fuel pressure.
Did you try spraying starting-fluid in the intake, see if the engine runs for a little bit.
Compression to be anything above 100 psi will firean engine ,sometimes lower too.

1998 jaguar xj8 consumes anti-freeze


First thing to check is the radiator cap seal. If it is not sealing properly, the water will boil off and then soon, the anti freeze will begin to disappear. Clean the metal surfaces and gasket and make sure it is tight ---or buy a new cap --but make sure there is a seal. If that doesn't cure it, you may have a head gasket leak that blows the coolant (anti freeze) into one cylinder. If that cylinder is tight, the coolant will only evaporate in the heat and be blown out the exhaust --not entering the oil pan. Check your exhaust when you start up. You may see white smoke, or even liquid, exiting the exhaust pipe, indicating a blown head gasket (then engine may run rough, too). If this is the case, there are reasonably inexpensive cures for this in some cases.

1995 Toyota 4Runner 3.0 V-6 overheated


If there is no visable water drip, or puddle, then it sounds like a head gasket could be the problem as they are aluminum engines. I used a block sealer from the auto parts store and solved my proble. It was called block seal, and has copper in it. Cost - $8.00, but you will also need anti-freeze and a flush kit, as you have to remove all the water and anti-freeze for the stuff to work. Hope this helps, can't hurt. Good luck.
