Somebody been using tap water in their radiator? The vehicle is old enough to have a lot of accumulated rust and crud in the Radiator which, depending on relative water quality and location of water pump could over pressure the system and have it squirting into overflow. If the threads of the plug have antifreeze on them it's coming from the OUTSIDE not the inside.

What would make my 1997 Buick century to keep over heating I have replaced head gaskets and put in new thermostat


Let's start with the simple and make sure the coolant mixture was 50/50 and not 100% coolant. That will make it overheat.
Second, thing I would check is if there's a code for your catalytic converter or oxygen sensor. If your converter is clogged, then it builds back pressure that overheats the engine.
Hopefully that helps. That's all I can think about without actually having done the head gasket replacement myself or having inspected the vehicle. And make sure the heads were resurfaced and inspected as well.

Head gasket or IM gasket? 05 rendezvous overheats..pushing fluid back to top of radiator or to reserve when cap is on. i think there's antifreeze on spark plug threads and maybe in cylinder for #2..ge


If it has the 3400 v6, better known as the 3.4litre, this motor was prone to head gasket failures. Antifreeze on spark plugs is a sign of head gasket failure, so is antifreeze in the oil. Have a mechanic put a dye in the cooling system that is detected with a certain light and that will tell you exactly where it's coming from. Headgasket repair is not cheap. May be easier and cheaper to replace the motor. Wish you the best!

Why is there a gurgling sound upon starting and the antifreeze blows out


Check head gasket. Pull spark plugs and perform compression check? Check plugs for fouling. Check engine oil for water/antifreeze
Hope this helps?

My 2001 Ford Taurus keeps running too hot to safely drive. Whenever the car is started fluid immediately gushes out of the plastic resevior that you put the water/antifreeze leading to the radiator. I...


You have an air bubble at the top of the engine.
The antifreeze spewing out of the overflow happens due to your perfectly functional radiator cap
passing the overheated coolant/air mixture out of the system into the reservior (in an attempt
to relieve overpressurization of the cooling system)
The sudden nature of your overheating comes from the boiling of the inadequate amount of
coolant/antifreeze in your engine, since it cant properly cool the engine, so it boils (overheats quickly), and pressure rises immediately within the cooling system.
The Fix is free: locate and open the (air) bleeder port at the top of the engine, and add the usual
50% coolant/50% water mixture to the radiator until the radiator is full to the level indicated in
your owner's manual (or the "Full" line). Then close the bleeder port and replace the rad (radiator)
cap.
The air bleeder port is normally located near the thermostat, and should be opened each time
that coolant is added to the radiator. The air bleeder port need not be opened when adding
50/50 coolant to the reservior, since the rad cap is going to be closed while adding coolant
to this part of the cooling system.
Warning: driving beyond the point where your engine temperature gauge indicates overheating will
destroy the car's engine - it'll seize up due to overheating, and the only fix for a seized/burned-up
engine is replacement (of the engine). Seizing an engine is really easy with an air bubble in the
top of the engine - you could easily burn up/warp the head, necessitating replacement of the head
and head gask

unfortunately these engines are known for this condition and for head gasket failure.with engine cold pressurize cooling system with spark plugs removed.look down into holes with flashlight after about ten minutes.....im betting youll see a puddle of coolant on piston...usually its cyl# 2 or 3.i cant think of any other possibility for system repeatedly airlocking other than a head gasket.good news they are probably one of the easier ones to replace.

How to flush cooling system, drain and replace with new coolant


First drain your rad. Second start the car and let it get up to temp. once your thermostat opens pop your rad cap and stick your garden hose in it.(when you drain the rad make sure you tighten the plug back up) Repeat process until clean water starts coming out.

Overheating they say head gasket changed


If you have white smoke from the tailpipe, coolant in the engine oil, engine oil in the cooling system, that indicates a head gasket failure. However, the most definitive way to test is to have a hydrocarbon test done on the cooling system (checks for exhaust gasses that obviously don't belong in there).
If the system comes up clean, you still can have either a leaking intake gasket, partially obstructed radiator (many times flush will go around obstructions not through them), a malfunctioning electric fan or fan relay, or even an obstruction in front of the a/c condenser or between the condenser and radiator (leaves, plastic bags etc) Don't forget though even if the cause is other than a gasket, if repeatedly or severely overheated the head gaskets can also fail. That is why complete testing is very important.
good luck
