Thread: Antifreeze leak? - Crownvic.net

Could a blockage be for a simple reason? Its running fine now and putting out warm air, is there anything i should check for?

If the "In" hose came off the intake then I would chalk it up to a worn clamp, If it came off the heater core I would think blockage. Since you got it back on we can rule out the nipple separating from the intake. Clamp it... Run it and watch for a few weeks. Keep your foot off the floor until you feel really good about the repair.

Coolant + COP = fried COP Thanks, I probably wouldn't have thought of that, I'll read the codes as well just to be safe. FYI, same line of reasoning, don't drive your car after washing the motor without checking to make sure all...

 Originally Posted By: AKA_Rizzo I think larry is after a heater core blockage ... Crap I can never remember which line is "Hot in" and "Cold out" from the heater core. The hose that blew off from that rear manifold nipple is the outlet to the heater core (or inorder words it's the heater core supply line).

Sounds like the intake manifold. The original on my car cracked in the same spot you describe.

I'd start by checking the hoses where the coolant runs outside of the engine and the radiator. Was the smell from the smoke strictly coolant smoke? If so the coolant might of hit your exhaust manifold and smoked or steamed up from the contact. How did the engine respond to this happening?

Does your car have the plastic intake manifold coolant crossover?

Wot luck!
