There are a lot of coolant fittings on the front (passenger) side of the engine. Radiator and heater hoses are there, as well as five or six (depending on the year) O-ring seals that can fail. But the most likely candidates are the coolant elbow or the water pump.

This is a photo of a 95 L36. The coolant elbow sits right above the water pump.

Irregardless of what section you post in, you have a responsibility as a 2-car owner to CLEARLY state what car you're posting about.

There has been confusion in several of your topics recently because of this.

I just realised what section this was, and remembered your other post about the 95....

I guess both of us need to put in a little more effort before posting, huh???

Top up the radiator and the overflow tank with coolant when cold. Go for a drive until the top radiator hose is hot. That will put the system under pressure, unless the leak is really big, and will make it easier for you to spot the leak.

Next, using a flashlight and a mechanic'* mirror, with the engine off, shine the light on the mirror as you move it around in front of the engine. The light will reflect from the mirror to illuminate the parts you want to examine. Look around the hoses and fittings and all around the water pump. Also look around the coolant elbow. Wouldn't be the first new elbow to leak. Sometimes the O-rings are faulty, sometimes the bore in the LIM or the tensioner assembly is rough or pitted and does not provide a good seal. Wiggle the water pump pulley. If it is loose, the pump will need to be changed and is probably the source of the leak, or soon will be.

Default firestone

firestone said that i am leaking antifreeze because i need a new belt tensioner? i just had firestone replace the plactic elbow that goes into the belt tensioner because it was leaking... now could this be possible.. or does it sound like a scam.
