5 4 Coolant Leak By The Intake Manifold Ford F150 ођ 1997 2003 ford f150 5.4 coolant leak by the intake manifold hello everyone. i noticed the smell of antifreeze while driving when i checked i can see the puddle of coolant at the underneath the intake manifold were the knock sensors go ( i believe that is the name of the sensor). Reason i'm asking, i have an 11' expedition 5.4 that started leaking coolant around the driver side of the intake manifold this morning. yea, i know, it's an f150 forum, but actual dirty hands on experience with anything this "new" seems hard to find. based on what i can find, the common consensus is to replace the oem manifold with a dorman.
5 4 Coolant Leak By The Intake Manifold Ford F150 ођ 5.4 coolant leak at the intake. hello, my new to me, 2000 sd with the 5.4 has developed a coolant leak under where the heater hose comes into the water jacket on the passenger side of the intake. its not the hose, you can see it seeping from between the aluminum coolant crossover deal ( across the front of the intake ) and the plastic manifold. Moral of the story don't ignore intake manifold coolant leaks! at least not for two years haven't seen ya in a while jason, that sucks with the coolant leak and with only 120,000 miles. isn't there a hose that runs under the intake that is known to leak antifreeze on these motors?.

Re: suspected vacuum leak 5.4 2v. by 3fox » sat jan 26, 2019 5:30 pm. 402 code likely is an open egr letting exhaust gas back into the engine. the motor will run very poor due to this . 354 and 358 are the rear cylinders both banks. they tell you the control leads between the computer and those coils are open.

Coolant leak at intake manifold. i have a 2006 f150 screw 4.6 auto 116k miles that has evidence of a small coolant leak where the intake manifold joins the head, this is on the drivers side directly under the thermostat housing. the t stat housing is dry and the hoses all appear dry. it's just wet right at the gasket where the manifold joins. Just wanted to give a video showing a common leak point on the 97 03 f150 5.4 4.6 engine. this is an example where the intake manifold gasket has failed at t.
