When the vehicle turns off - the heat causes the coolant to expand, and there is (should be) nowhere for it to go but out the overflow into the reservoir.
I believe the freeze plug is on the passenger side in the '99.
Where is the fluid coming from??
The engine block? A Hose? More investigaing will need to be done on your part.

Thanks!!

    it may appear to be coming from that area - however the starter seal is for gear oil - not coolant - so it must be originating elsewhere.

    Gravity will pull the coolant down - so look for the spot highest on the engine that is wet.

    Concentrate on tubing, hoses, and VERIFY it is coolant - not some other fluid - like brake fluid.



    Thanks!!

Why its my 84 ram charger 318 its leaking water thru the starter


There's no water there. It's probably leaking from above the starter and running onto it. Maybe a core plug, or freeze plug as it is also called, is leaking engine coolant. They are round holes in the engine block sealed by metal plugs driven into them. If they corrode or rust through, engine coolant will leak out of them.

My 99 cavalier 2.2 is leaking water / coolant on the left hand side of the engine area. It leaks while driving and while the car is not running. As far as i can tell its not leaking into the oil and not...


no freeze plugs are located on the sides of that engine... the front and back when viewed under hood.... i believe your resivoir- overflow is on the same side as you describe the leak so id check that first otherwise it seems youve a thermostat housing, intake manifold leak or another waterpump issue

My ford has a leak on the right side front it smells like coolant over a two day period all the coolant leaked on the ground what do i do?


Well depending on what engine is in this vehicle, it could possibly be the water pump that is leaking or possibly a "freeze out" plug on the block. I would say it is more than likely the water pump. If you have no noticeable leaks from any of the hoses or radiator, i would definitely suspect the water pump or possibly the thermostat housing may have cracked and started to leak. My suggestion would be to look at all your hoses carefullly and then check the housings where the hoses connect to the engine block, if no signs of coolant are present, check around the water pump for noticeable coolant leaks. Hope this helps in your search for that coolant leak.

Water leaking from block


Lower intake gasket is a common place to leak, coolant will run off the back side of the engine. freeze plugs can also leak. you will need to inspect the underside of the vehicle to locate the leak for sure.

2000 Lincoln Naviagator coolant leak somewhere by starter and block..is there a tube there and how do i get to it..need help..Quick..Badly...haha


there is no tube. You probably have a leaky freeze plug. Take the starter off to get at it. If you see it, drain the coolant, pry it out, and take it to the store to get the right size replacement. Also get some sealer while you're there. Clean out the edge of the hole so the new plug will seal. coat the hole well with sealer and use a large socket in the plug anlong with a hammer to drive it in. It should go in flush with the block, like the rest of them. Refill the engine with coolant, start the car and keep the system full while checking for leaks.
If the problem is not a freeze plug, please get back to me.

Got a slow leak at back side of motor not sure were from what all connects in that area and could freeze plugs have small leak or they just blow out


freeze plugs can get rusted and leak out coolant but if it is a freeze plug leaking, it will get worse. have you checked the intake manifold gaskets for a leaking problem. hope this steers you in the right direction.

1999 Gmc Jimmy water leak under the transmission


I believe the heater hoses are on the pass side on your truck, but have you checked where the heater hoses go into the truck? Otherwise on the driver side I would check 2 things after I checked the hoses 1. Intake manifold check it up and down they are bad for leaking at one of the corners. and it could be running down the back onto the ground. 2. check the freeze plugs. if you can go to autozone see if they will loan you a coolant press test kit other wise they are about 30$ for one .With the car off top the coolant off and press the system to what the rad cap is rated 15 or 16 ect. get your flash light and chase the drip. I would say the intake is your first shot at finding it. if you have a uv light you can also add dye to the system let it run and find it. First get some thing to stand on get on over the intake and find the coolant just remember it can leak from here and run and drop there. hoses , intake , freeze plugs
