Question about 1994 GMC Safari

1 Answer

1994 GMC Safari V6. Heavy loss of coolant, even when the engine isn't running. Appears to be coming from the engine block behind the A/C compressor bracket. Checked radiator, hoses and water pump. All good. Is this a blown out engine drain plug?

My 1986 gmc safari runs bad in O/D. pops thru the in take pulling a hill. exhaust smells bad when it happens. I am thinking coolant temp sensor.

Think Mass airflow meter. It needs cleaning. Just don't use any spray cleaner. Severe damage will result. Look for a spray cleaner that is made specifically for the job. Check the cam position sensor too.

Why is it that my 4.3 v6 gmc 1994 sierra gets real heavy when I turn on the a/c ? And when I step on the brake and gas to flor it it turns off on me ? Is it the motor that is tire or.....

GM AC compressors have been known to require a lot of energy to turn them. I had the same issue in my '86 SS Monte Carlo. I became accustomed a long time ago to not using my AC, even on hot days, unless I was traveling for more than 20 minutes to my destination. As for flooring it, many cars kick out the compressor because the engine needs all the power it can generate to do whatever you need, such as passing someone or avoiding an accident.

My 1994 Honda Accord is losing water from the radiator although no water has been under the car. I Also noticed the cooling fan which use to turn on after the car had been turned off, isn't coming on...

There is a fan sensor in the radiator. If the coolant level uncovers the sensor, the fans won't work properly. Your water loss is caused by the engine burning coolant. Look at the exhaust pipe to see if any water is dripping from the tail pipe with the engine running. Diagnosing the problem can be tricky. It can be a blown head gasket or a crack in a cylinder head or block.

Dodge v6 181 dohc tail pipe steam #6 cl missing,not a headgasket problem. insialled rt cyl head, still a problem/ dont know about intake pendim, or crack in block.engine ouerheated due to coolant...

A good one is the one with sodium and its silver in color, If you decide to use a block sealant and the instruction say add in radiator with thermostat out dont do it that way. To effectively use a block sealer no matter what brand you use, you have to do it the right way, the one on the instruction is for safety standard,and by law has to be written in safety concept, Here is the right way to do it. You add it when engine is cold add it behind the thermostat, install thermostat,close up the system add coolant water in radiator top it off. start the vehicle and top off radiator bring to 1200-1500 RPM until thermostat opens cap the radiator, run until upper radiator has pressure and all the while maintaining radiator level.this way seals the seapage

1994 GMC Safari. Rear a/c unit. I want to replace

It is not necessary to remove the ac lines for removal of the intake manifold.Remove the bolts that hold the ac compressor and it will allow enough room to access the intake.Make sure you mark the location of the number one cylinder on the distributor before removal.

A/C Compressor Question

Try grounding the LOW PRESSURE A/C SWITCH by the compressor, while trying to recharge. This will energize the compressor. Hope this helps.

First thing to check is the fuel filter. It is likely getting clogged and starving the engine for fuel under heavy load.
