Yes the manual for the 740 should be good enough. some of the hoses will go to different locations to the charcoal canister. and the Intercooler will probably have different pipes. Make sure you take pictures when you remove the hoses. Be careful especially around older rubber hoses on the Turbo - Intercooler system as these can be expensive to replace

FORD FOCUS LOSING COOLANT SUDDENLY


Check for white smoke out the exhaust. If you have white smoke then you are burning coolant and probably have a blown headgasket. Another way for checking a blown headgasket is to open the coolant overflow tank and run the car. If you see constant bubbles in the coolant then you have a blown headgasket.

DO NOT DRIVE YOUR CAR IF the gasket it blown as the engine will overheat and the cylinder head can warp/crack.

If there is no white smoke from the exhaust and no bubbles in the coolant system there is probably jsut a leak in the coolant system, visually check all the pipes and check around the waterpump housing for leaks. If you can't see a leak then pressure test the coolant system. A pressure test will push coolant out the leak and should help you find where it is.

Hope this helps

I own a 1989 740GL.The engine is the standard "


Wait - you said it has no spark, and then started asking about fuel injector relays. I am confused.
When you crank the engine, do the spark plugs spark? If not, the most likely problem is the trigger mechanism. The '89 740 used a sensor in the bell housing detecting flywheel position. This car is about due for its third sensor as the insulation on those things tends to degrade and need replacement every decade or so. If you are still on your original sensor, you have been very lucky to make it this far.
Find the person with the smallest hands you can find to help you replace that sensor and be careful not to drop the bolt down in to the hole where the sensor comes out. Also, if the sensor is rusted in place, be patient. Don't break it off in the hole.
If you are not getting fuel, you will not hear the fuel pump spin up for a second when you turn the key to the on position. You should be able to bypass the fuel pump relay using a paperclip at the fuse box. Just find the fuel pump fuse and power it from an other fuse. If that spins up the fuel pump and starts the car, then you have to worry about finding the fuel pump relay. I can't help with that because I have never needed to find it on a 740.

My 07 impala is losing anti freeze but nobody can find a leak anywhere how can i solve this problem


if cant find any spots on the ground an you're still losing anti-freeze, from my experience its always been the headgasket, if the headgasket isnt fully blown out your car will seem like its running fine an burn the antifreeze up during the combustion stroke of the engine, or it could be leaking onto the exhaust. check to see if theres any puddles of anti-freeze on top of the engine an check for leaks around the heads. if there is no puddles of leaks it could be your antifreeze is leaking into the engine an burning up during the combustion stroke

1989 nissan pickup headgasket


Your best bet is to purchase a service manual for that vehicle. It will have what you need in text and illustrations. You should be able to find the manual you need at the same store where you buy your gaskets, tools etc. for the project.

Coolant leaking on 1991 Volvo 740 Turbo Wagon


There is a pipe that connects to the rear of the waterpump right where you say it is leaking. I would guess the seal is leaking. Since you have to remove the pump to replace the seal, you should replace the waterpump.

These engines commonly blow the headgasket when overheated, and commonly overheat and leak coolant when the headgasket is blown. So it may be hard to say what came first, but either way you will need to determine if the headgasket is OK before you make any repairs.

Good Luck,

Blown head gasket


Yes, driving around with a blown headgasket is BADDDD....

If you've never replaced a headgasket before then I would suggest that you not try it without proper supervision and help.
On a v8 when you replace one headgasket you replace the other as well. The gasket kit comes as a set of 2 headgaskets and all other gaskets and o-rings that will need to be replaced. You will need an array of tools to accomplish the mission - some hand tools and some specialty tools for dismantling the cylinder head.
I'm really not trying to scare you off but this is NO SMALL JOB. It will require patience and it will require tools and prior knowledge - so get the HAYNES RePAIR manual for the car and read up if you decide to go for it. I did the headgastets on my Acura Legend v6 - and what should have taken 30 hours start to finish took about 55.
Good Luck and Happy Motoring!!!!!!!
