    Cosbysweater's Skunkworks 1987 Chevrolet C10

    By cosbySweater

    So as some of you are a ware of by now I've had this C10 for a while and have been kicking around the idea of selling it. I originally bought it to do a powertrains swap from my gremlin however it made more sense to just throw together another Vehicle with all the parts I had. That whole thread can be found in HERE . Anyway the setup I ended up with was very fun, 6.0, s475, 80e, terminator x. It was very fun and fast on the highway I ended up trying to sell it and had no takers on it... Read more

    D5252T swap on a Volvo 740

    By Smule5

    Hi! I'm from Norway For a bit of context: I have a Volvo 740 with a B230A engine and M47 gearbox. I'm going to use the same gearbox (because M90 diesel gearbox are hard to find) but I'm going to weld the clutch housing so that it fits the D5252T. I'm also converting the D5252T to fully mechanical with a dieselpump from a VW Transporter 2,4L Diesel (AAB engine) so that I don't have to struggle with the electrical wiring. I was just wondering if you could have used the stock flywheel from... Read more

    Help Squealing brakes

    By Reid_sickafoose

    On my 1990 740t my front brakes squeal or are sticking when I drive. When I am completely off the break they squeal and when I hit the brakes the sound goes away. My pads have good life and I greased the sliding pins and everywhere else that needs grease/antiseize. And the wheels spun freely when they were In the air. My front wheels have lots of brake dust and get really hot after a short drive. Now the thing that confuses me is it will only do it sometimes. I drove to work today and they... Read more

    940 Heater Core, Vacuum Actuator Repairs

    By philski o'flood

    I'm in the middle of a heater core replacement on a '95 940. The yellow line is currently plugged and I fished some broken stuff out of the vents. I haven't split the box yet, will do that today. Questions: What is the green book number for this HVAC stuff? Is is at Oz? What is currently available to replace the 2 way floor / defrost actuator? I've got Volvo # 9463042 (3522945) & Delco # 15-71438 and can't find anything to buy. What's this busted thing for and am I missing pieces. Center... Read more

    How would I clean out the cabin air intake?

    By AGraham

    I was upside down in the driver's side foot-well with a brake pedal in my right eye socket and a flashlight between my teeth yesterday going to war with the heater control valve when, who'd of guessed it, fall came early! Leaves, needles, grass clippings, detritus galore. The entire central tunnel under the blower and exchangers was PACKED; there was a fair amount of moisture under the driver's side carpet as well; thankfully, no rust. How does one clean out the intake under the windshield... Read more

    Automotive Diagnostics with a Cheap Handheld Oscilloscope

    By bobxyz

    Overview Over the last few years, simple handheld battery-powered oscilloscopes have become available for less than $40. This thread is about the FNIRSI DSO152 oscilloscope, and how it can be used for automotive diagnostics. The examples here are from a Volvo Redblock Engine with a Bosch LH2.4 Fuel Injection System (pre OBD-II). Many other cars of the same era, late 1980s and early 1990s, have similar systems. The information is split up over several posts: - Overview and What to... Read more

    Snapped Whiteblock Head bolt in block…dissolve w/nitric acid or Alum?

    By Kjets On a Plane

    Soo… …it’s been a long time since I’ve done this (and kind of can’t believe I did / kind of know better?), but managed snap the bolt extractor off after drilling a lovely centered hole with a guide bushing and plenty of pressure on the bit all the way thru the remaining ~2” of head bolt. Drilling the extractor looks neigh impossible or really annoying. There’s no particular hurry. Sooner would be better, but the car doesn’t need to leave tmw and lower risk and less frustration...

    standalone PWM fan controller with LCD display for brushless fan.... ditch the 850/940 electric fan.

    By 740atl

    THIS THREAD IS UNDER CONSTRUCTION>>> I NEED TO ADD A FEW MORE DETAILS AND GET SOME MORE PICTURES. I completely melted a 30 amp fan relay fuse not long ago this Summer and the old 940 electric fan stopped working in a very inopportune location at a very inopportune time… and predictably, the car started overheating. I nursed it back home convinced that something else was the problem only to find the nuclear-accident-level-melting action done to the fuse. I popped in a new fuse... Read more

    Crank no start saga

    By Anson.drives

    So I’ve got this 89 240 in my shop atm. And for some reason injectors and spark only happens when the key goes from key 3 to key 2 (run) No injector pulse while cranking and no spark while cranking I’ve tested ignition stage module fuel Ecu ,EZK,CPS, Coil started with all the pin from the ignition switch falling out then repining that. I’ve used Daves schematics. But mostly the Bentley book for the diagrams. I’ve traced almost every wire in the system still no luck. Also all the parts... Read more

    Hello guys, I was out and about the other day and saw some ratted out 91 745dl on someones driveway. went and knocked on the door and asked how much they wanted for it.... ONE CRISP ABE LINCOLN. Runs and drives, but has a severe ps rack leak. Does anyone know if there's a way to tell which type of steering rack the car has so I can order a rebuild kit? How much of a PITA is it to rebuild the rack? I believe it may be a ZF based on year but I could be wrong How is someone selling a... Read more

    M90 Swap to 1991 960

    By Saggy960

    Hello, thinking of manual swapping my 960 now that all the suspension work is done, ive already sourced the m90 but now comes the question of the rest; The car currently has the AW30-43 so will be needing the flywheel, clutch assembly, pedals and drive shaft From which cars should I source these parts? Clutch assembly can be sourced from a v70/850 I believe, how about the flywheel? Not aiming for a dual mass. What about the rest? Regards

    Overdrive disengages by itself

    By resunoiz

    Yesterday went to a trip trough the mountains. When I left home after 4-5km I get to motorway, at 80km/h I pressed the cluth and engaged the overdrive as usual. It suddenly went off. I tought I may have touched the button by hand, re-engaged, the OD after 2-3kms went off again. Re-engaged (I think wothout pressing the clutch this time) and it started, remained engaged normally. Made 300km+, no other strange behaviours. Today I took the car to the insèection, OD started to disengage again... Read more

    Regina heads fuel pressure issue solved

    By oleseahorse

    Stupid. Owned Volvo 240s and now a 740 for 40 years. Car started running poorly with some hesitation and bucking. I checked fuel pressure + sometimes got 28 PSI sometimes 23 and I figured my fuel pump was on its way out. I had the shop replace the fuel pump + the fuel filter to no avail. I then replaced the fuel pressure regulator initially with a 2.5 bar unit and then subsequently with a three-bar unit also to no avail. Pinched the return hose and removed the vacuum hose still 28 PSI. With... Read more

    3D Printed Parts Thread

    By Maximum Turtles

    As our Volvos grow older, many parts become harder to find and lose their aftermarket support. Fortunately, several members, myself included, have been quietly producing their own parts (like stock and modified) through the medium of 3D printing. This thread is to be a list of parts people have already designed and are ready to print, as well as a place for people to request parts.

    Volvo Redblock tappets stuck

    By Buß

    Hi, i just recently bought myself a Volvo 940 B230FB with just over 400.000km on it as a non-runner. I threw a new timing belt on it and it ran just fine. A day later it wouldnt start so I checked under the valve cover because the crankshaft took lots of force to turn, so I took the head of for inspection of the crankshaft and valves. The problem of the crankshaft not really turning was soon identified as valves not returning to their seat when closing and not wanting to open with easy... Read more
