Question about 1988 Jeep Cherokee

Power steering is out. overflow tank blowing smoke

My 1988 Jeep Cherokee died at a light, and started blowing smoke from the antifreeze overflow. I let it cool down, refilled it and started it. My power steering went out and when I got home a few minutes later, it was smoking heavily again. Is this just a pump and thermostat issue? Or could it be the dampener for the belt causing problems?

The key to this is likely the belt. Is the belt there? Is the tension correct? If OK, do all the drive and driven pulleys turn when it is running? Did it overheat again on the trip back home? Check the system for leaks. Even if you find the problem was not the thermostat, change it. Do not change the pump unless it has a leak or other mechanical failure. Like a bad shaft bearing.

Engine overheats, loses power, starts back up but dies when put in gear

I hate to tell you this but... If it overheated you probably have at the very least blown a head gasket. The best thing to do is run a compression check and that will tell all. Hope that helps

Changed a frost plug on a 99 jeep cherokee and used new antifreeze and now gettin lil warm instead off hot heat inside ...why?

You have an air bubble in the coolant system. When the engine is cold, loosen the radiator cap to the first notch. Start the engine and warm to operating temperature. Turn the engine off and top off the radiator and overflow tank. Tighten the radiator cap and allow to completely cool down. After the engine is cold again, top off the overflow tank. The heater should work properly.
Good luck.

First thing you do is check the antifreeze level. Is the plastic overflow tank up to the level on the tank? You will see a mark for the level it should be if cold and a level it should be if hot. If it is low, add antifreeze to the tank as well as the radiator (take radiator cap off while engine is cold). Get the level up and that should fix the problem. If it doesn't, or the level of antifreeze is where it should be, then you could have a thermostat that is stuck open which doesn't allow the coolant to warm up before being circulated. Replace that and I would bet you have all sorts of heat coming. Both of these fixes are very easy on the bank account.

Good Luck

Jeep running rough; black smoke from tailpipe; dying occasionally

Have you taken a spark plug out yet? You may have fowled them out. if they are not clean and have a whitish tone to them, then they need to be replaced.
