When to replace timing chain on Chrysler 3.5L?

Chrysler probably should have used a timing chain in this engine, but instead opted for a less expensive timing belt. The factory recommended replacement interval for the belt is 100,000 miles. The early 1993-’97 3.5L engines are non-interference engines, so if the timing belt snaps or jumps time, the engine won’t bend any valves.

Why is my Chrysler 3.5L V6 running hot?

Leaky head gaskets are also a common problem on these engines. If the cooling system holds pressure, and the cooling fans are functioning normally but the engine is running hotter than normal, it’s probably a worn water pump. If you do change the water pump, change the thermostat too.

What kind of cooling system does a Chrysler 3.5L use?

The cooling system on the 3.5L uses a water pump with a molded plastic impeller. The design is more efficient than a typical stamped metal impeller and produces less cavitation, but the soft plastic impeller can be eroded and worn down by rust and sediment in the coolant.

What to do if your Chrysler 300M has a leak?

When the air conditioner in your 1999 Chrysler 300M starts blowing hot air, you likely have a freon leak.

Why is my GM 4.8l engine running too lean?

The engine may be running too lean, due to a leaking intake manifold. Too lean means too much air and not enough fuel; according to the power control module (PCM) calculation. When the engine is cold, not all sensors function. As the engine warms up the oxygen sensors report the lean condition.

Why does my GM V8 engine misfire when cold?

Because, GM V8 engines are very prone to a rough idle and engine misfire when cold. The check engine light may also come on, with codes P0300, P0171 and PO174. But, as the engine warms up, the engine misfire or rough idle tends to go away; which seems confusing.

What causes cold stalling on a fuel injected engine?

On fuel injected engines, cold stalling can also be caused by conditions that upset the air/fuel mixture. This includes vacuum leaks or unmetered air entering the intake manifold downstream of the airflow sensor, a faulty throttle position, MAP or oxygen sensor, dirty fuel injectors,…

Why does my 300m engine get hot when I run a / C?

Also, the rad is a cross-flow design, meaning the coolant moves from side to side as it is cooled. The fact that one fan blows cooler air than the other is also normal. When you run the A/C, the condenser, which sits in front of the rad gets hot. The air passing over the condenser then passes over the rad.

What to do if your 300m engine overheats?

He’s worked on 300M cooling systems before. When I turn “ON” the heat and crank the fans wide open, the temp will drop BUT not near the normal operating temp. The lower radiator hose still stays cool enough to touch. When I turn “ON’ the AC, the temp drops beautifully to normal operating temp.

When does cold, engine shakes and hesitates during acceleratio?

After the vehicle sits overnight (cold engine), during idle, engine vibrates and after about a minute vibration’s gone and comes back again a minute after – this cycle goes on and only stops when the engine becomes hot.
