If it is in the winter make sure the radiator is full of water with antifreeze before starting the car. If this leak is not too severe it should be ok to drive a couple of miles to a mechanic.
The heater core is leaking coolant.
Leaking from the water pump at the back on the passenger side.
Replace it, should only coast a few bucks at auto parts store.
If coolant is leaking inside your cabin, you have a leak in the heater core. The only repair is to replace the heater core. Most auto parts stores sell them.
i will switch the question to Auto Zone , this guys at Advance dont give 1 rigth .
A 1999 Chevrolet Tahoe will take approximately 16 quarts of coolant. The coolant can be purchased at any auto parts store such as Auto Zone.
no!!!!! stop and have the head gasket replaced that is most common reason for coolant leak into oil pan. ---------------- After 35 years of owning my own auto repair shop my experience has been that the most common reason for antifreeze in the oil is a bad intake manifold gasket....Bad head gaskets commonly cause overheating or antifreeze getting into a cylinder and causing a rough running engine and white smoke coming out of the tailpipe.
Your description sounds like engine coolant to me.
First I eye-ball the radiator and all coolant related parts then if the leak isn't obvious I pump 15 psi of air pressure into the cooling system with a cooling system pressure pump. This usually helps locate the source of the leak.
If the Red Coolant meets the specifications required by you vehicle manufacture you can perform a coolant flush on you system before replacing with the new coolant type.
To flush an engine of coolant in the engine of a Kian Spectra refer to the manual. Auto manuals can be purchased at auto part retails or in bookstores.
You can find a good coolant temperature sensor at Auto Parts Warehouse at http://www.autopartswarehouse.com/models/toyota~tacoma_pick_up~makemodel.html. You may also find them at Advance Auto Parts at shop.advanceautoparts.com/.../product_Engine-Coolant-Temperature
