ford f350 runs good until it warms up good then shuts off and will not start. when it cool down for a day or so it will start right up. what could be the problem


it sounds like to me your

it sounds like to me your truck is over heating and when it starts to over heat some vehicles shut down to protect the motor you should check your coolant and oil levels. You could have problems with your radiator/ hoses or it could be your fan not coming on to cool the engine down. when you drive it roll down your windows and turn the heater on full blast and see if that helps then you will know if it's the fan.

here's a bulletin on hot start problem, let us know if it applys to your concern.

HARD START AFTER HOT SOAK - Article No.
5.8L AND 7.5L ENGINE WITH HOLLEY 87-19-13
4V CARBURETOR - OVER 8500 LBS. GVW

LIGHT TRUCK: 1983-87 E SERIES, F SERIES

ISSUE: Hard starting at normal engine operating temperature after a 15 to 60 minute hot soak may be caused by fuel vapor getting to the engine through the fuel bowl and evaporative emissions system. The fuel vapor will cause an over-rich engine during restart. Volatility of gasoline may also cause increased amounts of vapor when gasoline is warm. The affected vehicles are 1984-87 E and F Series with a 5.8L engine and Holley 4V carburetor and 1983-87 E and F Series with a 7.5L engine and Holley 4V carburetor.

ACTION: To correct this, install a Hot Idle Compensator (HIC) valve using the following service procedure.

5.8L Engine

NOTE: Use original production PCV line.
Figure 10

1. Assemble HIC valve (E1TZ-9B532-A) and Tee (379507-S), Figure 10.

2. Install the HIC valve in the PCV line, Figure 10.

NOTE: Position the HIC valve in the PCV line over exhaust heat cross-over and under spark plug wires.

7.5L Engine

1. Remove steel PCV line.

2. Install a new PCV line (E6HZ-6A664-A). The new PCV line fits from the PCV valve to the front of the carburetor. PCV line must be routed along the right rocker arm cover under spark plug wires.

3. Assemble HIC valve (E1TZ-9B532-A) and Tee (379507-S), Figure 10.

4. Install HIC valve in the PCV line, Figure 10.

NOTE: Position the HIC valve in the PCV line over exhaust heat cross-over and under spark plug wires.
