Replaced water pump on a 1999 7.5 GMC .Fill radiator antifreeze went in oil pan why

SOURCE: 1999 kia sephia leaking antifreeze

I have a 97 Sephia with what sounds like the same configuration. The tube is for the heater and there is an "O" ring on the metal tube that goes bad over time. You can replace the gasket by removing the metal tube from the engine, or the water neck and replace the o ring.

check all hoses .from thermostat to radiator to water pump. check heater hoses.if all is good .make sure your water pump not leaking around the gasket area.if all is good.core plugs could be leaking.

thermostat should be replace on over heated engine, the spring loses tension, probaly not problem, most like head gasket if over heated severly, if you have a air pocket & wornt purge thats one sign,press test on cold engine let sit at start up run slightly rough may see & smell coolant at tail pipe, could also pull plugs may have one wet all crude checks, there is also chemical you put in coolant & use a a stripe for combustion I think napa or snap on sells, alsoyou could do tear down & inspection wish you luck not sure what engine or car you have grand am or grand prix my guess a GP with poss 3.4 more likely then 3800 engine

SOURCE: im losing anti freeze i looked under the car and

If the engine is the same as the 2002 Impala 3.8L engine, the problem is most likely cracked connectors where the coolant enters the engine block. There are two L-shaped plastic connectors that connect the coolant lines through the metal block attached to the tensioner arm to the engine block. Common problem and parts are available from the dealer for under $20, but takes several hours of disassembling and specific torque specs. Just replaced mine over the summer.

If your hoses are intact, it still may be the water pump. When the seals fail, there is a small diameter hole at the bottom of the pump which will start to seep so it just answers to gravity and the oil pan is the lowest part.
