To replace the motor mounts on an '85 CJ7 with a 258 engine, first ensure the vehicle is securely lifted and supported. Disconnect the battery, then remove any components obstructing access to the motor mounts, such as the fan shroud or exhaust pipes. Use a jack to support the engine, then unbolt the old mounts from the engine block and frame. Install the new mounts by reversing the removal process, ensuring all bolts are torqued to the manufacturer's specifications.
I have a 1983 CJ7 Jeep Laredo which originally had a 258 6cyl AMC motor which you could source from an old Rambler Hornet and a couple of other Ramblers that had that motor. I installed a AMC 360 V8 motor from a 1977 Rambler Matador which bolted straight on to the Torqueflite 904 auto gearbox which I installed a 2 stage kit and highstall torque converter. Being in Australia I used Holden engine mounts and Holden WB radiator and fan shroud. She's one quick Jeep now.
Should be the 258 cid I6
On the windshield frame, right in front of the driver, behind the dash pad. The motor mounts to the inside wall of the windshield frame and drives the linkage that is inside the frame.
yes. jeep stanardized bell housing bolt pattern in 71 i believe. just motor mounts and exhaust and radiator to worry about.
You can replace the 258 6-cylinder engine in a 1976 Jeep CJ7 with several options, including the AMC 304 or 360 V8 engines, which are direct bolt-ins due to compatibility with the existing transmission and mounts. Additionally, small-block Chevy engines, such as the 350, can also be fitted with appropriate adapters and modifications. Other alternatives include modern options like the GM LS engine series, though this would require more extensive modifications. Always ensure that the chosen engine is compatible with your vehicle's drivetrain and emissions regulations.
It's not important, just tighten it.
The firing order for the 1986 Jeep CJ7 with a 258 cubic inch (CID) inline-six engine is 1-5-3-6-2-4. This means the cylinders fire in that specific sequence. The cylinder numbering starts with the front of the engine, where cylinder 1 is on the driver's side.
My manual says 20-25 ftlbs...
12 mpg with a 1981 CJ7, 258 engine. -------------------------- 1982 CJ7 Golden Eagle with a 3-Speed Ford 302-V8 engine and 33in Goodyear (Hummer Radials) in perfect mechanical condition - I get about 15 in the city, but I'm careful about how I drive. (hardly ever run the AC)
The stepper motor controls idle speed. A bad motor allows the engine to rev at idle. It often sounds as if the timing is off but not so- It's the stepper motor malfunctioning. I own a stock (original owner) '84 CJ7 6 4.01 straight 6 with a bad stepper motor. There is no replacement part for this stock item - Jeep discontinued it recently. There's no after-market part for this year ('84) unfortunately. You'll need to check out salvage yards or perhaps something custom made advertised elsewhere. I hope this helps somehow.
1-5-3-6-2-4 Looking from the cooling fan side.
