My 1991 740 volvo turbo doesnt start specially during the morning.Is it comes with a cold start valve?
You probably mean Overdrive solenoid, on the transmission left side Hope it's help
Remove the gas line (depressurize it first), and remove the electrical connector. Then remove the two bolts that fasten the valve to the intake manifold. The valve is below the manifold so it is not very easy to access.. Installation of the new one is reverse of the removal.
Broken valve spring
In the 1989 Volvo 740 GL with a Bosch system it is located just above the steering column on the dash.
Not necessarily, most do however.
If you have done a compression check the next step is to take off valve cover and look.
I had this problem on my 1989 740 Turbo, random stalls, slowly getting more frequent, Replace the fuel pump relay, it is located behind the ashtray, behind the fuses...
i have a 1989 740 and mine is located on under the hood it the green 1 on the side next to the air filter
If you are referring to the RPM riseing and falling by itself (Hunting) you might want to check to see if the intake is clean. I have had problems with my 740 not wanting to idle when the throttle valve area is coated in oil and grime. After using an approved spray cleaner it idled correctly.
under the left hand bumper
The answer is 740
behind the fuses, below the radio, behind the lowest box in front of the shifter.
74 x 10 = 740
It is below the throttle body, mounted in a rubber bracket. Follow the 3/4 inch hose from the air filter box. it goes to IAC valve.
20% of 740 is 148. 20% OUT of 740 would be 592.
100% = 740 10% = 74 5% = 37 740 - 74 - 37 = 740 - 111 = 629
740 K could mean: 740,000 (number: the "k" stands for "thousand") 740 degrees k (temperature) 740 * k (in maths, to multiply 740 and k together)
740 is composite.
The multiples of 740 (which are infinite) are all divisible by 740, including these: 740, 1480, 2220, 2960, 3700, 4440, 5180 . . .
The "PCV" valve is actually called the "flametrap". Its located on the driver's side just behind the intake assembly. If you go to www.brickboard.com they have a great FAQ just for the 700 series Volvos.
try changing the crank shaft sensor,which is located on the firewall on the 1991 740 non turbo sedan,i had the same problem and just about a month ago had to replace it.
