SOURCE: Freeze Plug Leak on my 1996 GMC Jimmy

i would hardly call this repair simple or inexpensive. the part itself yes the labor probably not. i have made this repair myself to my 97 jimmy if you have 4 wheel drive the transfer case up front makes this repair next to impossible from the underside of the car plus the fact that it is behind the motor mount means the the mount must be removed. this involves raising or removing the motor. simple? on a car of this age you will probably find (as i did) the motor mounts are damaged might as well replace them too the parts are fairly inexpensive. also look into replacing all the plugs so you dont have to do this again in a few years. oh yea use the proper antifreeze mix in your radiator water is what rusts out the plugs

9141 does not exist I will assume it is DTC P0141 HO2S Heater Performance Bank 1 Sensor 2

The VCM has the capability to monitor this process by using the Heated Oxygen Sensor (HO2S Bank 1, Sensor 2). The HO2S (Bank 1, Sensor 2), located in the exhaust stream before the catalytic converter, produces an output signal which indicates the storage capacity of the catalyst; this in turn indicates the catalysts ability to convert the exhaust emissions effectively. If the catalyst is functioning properly, the HO2S signal will be far less active than the signal produced by the Heated Oxygen Sensor (Bank 1, Sensor 1).
When the HO2S temperature measures below 360°C (600°F), the sensor will not produce any voltage and will behave like an open circuit. This will result in an Open Loop operation.
The HO2S heater provides for a faster sensor warm-up which allows the sensor to become active in a shorter period of time and remain active during long extended idle. The DTC P0141 determines if the HO2S is functioning properly by checking the response time of the sensor. This DTC is a type B DTC.

SOURCE: 2001 gmc jimmy engine warm but heater blows cold air

Disconnect the heater hoses from the water pump and the intake manifold. Get a compressor and blow out the hose (put the air hose into the the hose that came off the mainfold. then flush the system and replace the antifreeze.

look under the front of your blazer, just below the bumper, and you will see a little access door in the plastic guard. Open this door, and you will find your oil filter.

I have a 1999 jimmy with 115,000 miles and I,m hearing about the intake manifolds leaking antifreeze what concerns should i have with my jimmy and what type of antifreeze should I be using


A leaking manifold could cost you a VERY expensive repair. I recommend getting it fixed as soon as you can. And with the antifreeze...seeing how it it a GM it should take DEX-COOL. But look under the hood and look for a white sticker and it should say "This vehicle takes DEX-COOL coolant. Do not mix with any other coolant" and if not the cap for the coolant should say so. If so, then obviously you need DEX-COOL or universal coolant. Universal will not harm anything, but I would use the manufacters reccommendations just on the safe side.

1999 GMC Jimmy Running Hot w/ Engine coolant reservoir empty


I guess the burning question is , where is the coolant going.
Is this a 4.3 engine? How many miles does the vehicle have?
Has the intake gasket been changed?
I'm guessing a can of "Bars Leak" may cure your problem.
Let me know.
