    Is it coming from the bottom of the water pump (weep hole)? Point a flashlight there with engine running. If yes, replace water pump.

First check for antifreeze in your oil. If you have antifreeze in your oil you have a blown head gasket. Ifnot you probably have a bad water pump. The pump is above the crank in the front of the engine. The water pump is the common leak as long as the hoses are good. Check carefully for a antifreeze trail. Then follw it to the source. The easiest way to do this is to pressurize the system. You may have to take it to a shop for this, but it will show the leak source the fastest.

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.

Lower manifold leak 2004 chevy


If the lower (intake) manifold is leaking, which is very common, then you should either have an external antifreeze leak, or antifreeze into the oil. Oil will not go into the antifreeze. The coolant used in this car (DexCool) does, however, form an oily substance on the surface over time. I would recommend having the antifreeze flushed out, and the reservoir cleaned.

1990 Nisan Maxima threw all 3 serp. belts-crankshaft pulley went bad. Replaced all of these and then it started to rough idle (head gasket leak?) installed stop leak (ceramic) and it starts well one time...


there is a good possibility that your engine may have ingested some of that antifreeze and if it did thats one of the reasons why your engine idle is rough the reason why its hard to start is becaus the anti freeze is being compressed by the pistons when you start the engine check the tailpipe for white smoke or an antifreeze smell As far as the stop leak its sometimes a temporary fix for a bigger problem .Check your antifreeze level (when it cools down).for a low fluid level

Heater blowing cold air


If there is a internal antifreeze leak, there will be antifreeze mixed in your oil. Check your oil. If there is antifreeze in there, you probably have a bad head or base gasket. Worst case scenario is your block is cracked somewhere. Check your heater core and the lines as well. If the heater core is bad it will be leaking.
Check the thermostat housing for a leak. Sometimes
the antifreeze will leak from there, and burn on top of the exhaust instead of dripping onto the ground. Good luck

Would my thermastat be causing my car to lose coolant,


It may if it is not opening up at the appropriate temperature and the coolant is overflowing as a result. Try putting a piece of carboard under the vehicle and look to see where it is leaking from it may be a waterpump which can be a serious threat to the engine, it can cause if leaking the timing belt to break find out immediately where the leak is, if you look under the car and see antifreeze dripping off the mainlower center crankshaft pulley it is probably the water pump.

White smoke comes out of tail pipe and burns at least almost a quart per week, what causes it. Please help


Usually white smoke all the time indicates a leaking head gasket (leaking coolant in the cylinders), which should be fixed right away because piston rod bearings and crankshaft bearings really don't like antifreeze... Can cause serious engine damage.

In rare cases, white smoke only at cold startup (stops right after startup) is an indication of too much fuel in the combustion chamber
