Reader question I have a 1998 Chevy Blazer 4.3 v6 4x4. My engine is running hot, i have to keep filling the radiator w/ antifreeze, but the visible leak is coming from the backside, center of the engine. It looks like its dripping off the left side of the transmission pan. I doubt its the water pump, or a cracked radiator due to the location of the leak.
Like I said its located almost directly under the dashboard. It could be the heater core, or an intake gasket, or possibly a freeze plug? I am stumped. If i open the cap while its hot, rusty looking antifreeze pours out. I use green antifreeze.
The heater blows cold air, the oil gauge is erratic, sometimes there is a high pitched whine coming while u accelerate, sometimes it accelerates slowly, I don't know what it is. any advice would be great. Thank you. Chris
Howdy there Chris
You gotta get a cooling system pressure test done to really determine where the leak is coming from. This is a quick and easy test just about any mechanic or fast lube place can do while you wait.
That rusty coolant definitely will need to be flushed out and replaced with new once you repair the leak. The leak could be something is simple as a heater hoses that is leaking at the back of the engine..or something more complex like an intake manifold leak. Don’t guess, get the test! Keep me posted will ya?
Blessings,
Austin Davis
