If your gmc safari cargo van overheats when the ac is on, your radiator and cooling system may be clogged and not working at peak efficiency.

Make sure your radiator cooling fan goes on as soon as you turn the a/c on.

Just had my thermostat replaced, van smells hot, runs at just below temp midrange and the coolant bottle is empty? should I fill it with water or coolant? why is it smelling hot?


coolant of course . 50 /50 blend and probably the PINK stuff .sometimes when they get just a little low they will smell HOT even when showing normal mid range on the gauge . there should always be some liquid in the overflow jug

I have a 2003 gmc safari cargo van, and the problem started when it got hot outside, it started overheating and lost power, i replaced the thermostat, coolant, spark plugs, and MAF sensor, the overheating...


Hello and welcome to FixYa!

I strongly suggest that you replace the transmission fluid. If the fluid is burnt the transmission tends to be sluggish and finds it hard to shift gears. This will surely give great stress to the engine. Once the fluid is replaced, smooth drive and shifting will be noticeable.

Hope this helps and thank you for using FixYa! Have a good one!

When i take off from a stop my rear end clicks then feels like a foward jerking, 2004 GMC safari cargo van.


DISCONNECT YOUR DRIVE SHAFT FROM THE REAREND THEN TURN YOUR REAR BY HAND AND IF YOU STILL HEAR CLICKING OR GRINDING
DETERMINE FROM SIDE OR MIDDLE. IF NOT BRAKES THEN REAREND BEARINGS. THESE REARS WERE FAMOUS FOR REAR BEARINGS.
AFTER REPAIR INSTALL SYNTHETIC FLUIDS.

97 GMC Safari Cargo: engine turns but will not start


Safari's tend to have problems with the rotor button on the distributer. Your's may be going bad. At first the van will stall as you described, due to a jarring of the motor, ie: a bump. etc., and then it will restart.

After a while the rotor button will fail completely.

I have had this same problem with two safar's and this is the solution that I have found.
