Depends on the motor. According to the Engish Haynes manual. B21 and B23 will not, B230 will.
Yes...Well it is an interference engine, not zero clearance. Which means when the timing belt breaks the pistons with "interfere" with the valves.
Not mine , I was doing about 70 when my belt broke . It took me 4 hours and $20 to know for sure boy how aggravating not knowing if my valves were bent or not. The good news is that my volvo with 345,000 miles fired right up when all work was complete. 24mpg and no payments.The above answer may be true for that owner but I do not see how it is possible. The 1986 Volvo 740 GLE 4 cylinder is an interference engine and as such if the cam belt breaks you will almost certainly have internal engine damage. The belt should be changed every 50,000 miles.
There is no timing belt in that engine. It has a timing chain.
As all Acura Legends 1986-1995 equipped with a cam belt are interference engines if the belt breaks you will have serious internal engine damage. Neglect this service and you will pay dearly.
No, No, and YES...!No, not changing the timing belt doesn't effect performance or fuel economy of your car.No, if it's not changed and if your Volvo engine is the single overhead cam type, it is a non-interference type engine and if you don't replace it then when the belt breaks, you'll be left by the side of the road, it's not really a roadside repair at several hours to replace....However being a non-interference engine it won't damage your engine when it does break.Where it is a YES....If it's a dual overhead cam engine (like the 4 cylinder 16 valve) it is an interference engine. If you don't replace it at the recommended interval or risk not only ending up by the side of the road, when it does break you'll end up with an empty wallet to repair it.
If your Volvo is an automatic transmission try changing the fuel filter.
If you have plug wires, you can use an inductive timing light. Instructions will be included.
Where is starter relay on a 1986 volvo 240gl
pull and plug vacuum line to spark computer, adjust timing
1986 should be carburatored and it is not required. That would only apply to a fuel injected engine.
Check the intank fuel pump and primary pump and fuel filter also check engine timing.
Without knowing the model year or the type of engine : No The 3.0 liter " Vulcan " V6 engine and the 3.8 liter V6 engine use ( 1 timing CHAIN ) The 3.0 liter " Duratec " Dual Over Head Cam V6 engine has ( 1 timing CHAIN to each cylinder head , so there are 2 timing CHAINS ) ( even the 2.5 liter four cylinder engine available in the 1986 or so ,Mercury Sable has a timing CHAIN )
