SOURCE: My 1988 chevy sport van makes a lot of noise when

I think the fan clutch is locked up. With the engine off the fan should rotate by hand with a cold engine. When the engine heats up, the fan clutch locks up to cool the engine, and unlocks after it cools it down to approx 160 deg F. This is to help with fuel milage and noise.

SOURCE: leaking heater core under floor

Hello, The ductwork for your A/C has a drainline running through the Firewall or floor pan. This drainline makes the sweating condensation from your A/C exit your car. If the water you see is clear and you have not lost Antifreeze, then it is simply the A/C working.

However, if the fluid leaking is Antifreeze, then the heater core is bad and must be replaced. Sometimes you have a water valve in the system and it can be modified to prevent Antifreeze from running through the heater core.

If the water lines going in and out of your heater are the same diameter, you can get a fitting and remove both heater hoses from the heater and connect the 2 hose ends to bypass the heater altogether. This will give you time to get your heater core replaced.

My 1999 chevy blazer wont shift out of low


My husband had the same problem with his 1988 S10 Blazer. We drained the tranny, cleaned out the pan and put in a new filter etc. Filled with new fluid and all problems solved. Shifts better now then before the tranny service.

2001 Blazer has vibration, Can feel vibration through the steering coulmn and floor boards. Sounds more pronounced on drivers side of car. Sounds less when making right turns. No noise when standing still....


You didn't say whether your blazer is a 2wd, 4wd, or awd. It sounds like you have a bad wheel bearing. If it's an all wheel drive, it could be the CV joint. You should also check for loose lug nuts and low tire pressure.

How to remove automatic transmission from 2001 s-10 blazer 4.3 V-6


Before you do anything, park vehicle on flat, level concrete floor in an area larger than the vehicle free of clutter, children, pets, and nosy neighbors or uninvolved personnel. Actual helpers are permitted, and in fact one is recommended, to act as a real helper/gofer, and to take action in the event of an accident or emergency. Let some one know you are going to be doing this, and carry a cell phone with you under the vehicle.First, remove negative cable from battery. Second, using a regular floor jack and good jack stands for added stability, raise the front of the vehicle high enough to get under it, and remove the drain plug from the transmission fluid pan (if applicable), or remove fluid pan from transmission, allowing used fluid to collect into a catch-pan of at least 3 gallon capacity. If you have to drop the pan because you don't have drain plug, remove the filter (it just snaps into the valve body), then replace pan with a bolt at each corner; don't worry about the gasket or torque specifications. Third, disconnect the two fluid lines from the transmission, using line wrenches to avoid damage to the line fitting nuts. Using wire or twine, tie these lines off to the frame out of the way of the transmission case. Fourth, unplug any electrical connectors and disconnect the 5-guage red starter wire from the starter motor, the shift linkage, TV cable, and speedometer cable (if so equipped) at this time. Fifth, jack vehicle on all four corners to a height of at least 24"from truck body floorpan to ground. Jack up vehicle all the way around, not just the front. This job CANNOT be done safely on wheel ramps. The entire vehicle must be off the ground, and VERY securely supported by the frame. This is dangerous if you do not make absolutely sure that the vehicle WILL NOT FALL.
Sixth, remove the U-joint clamps from the front yoke of the drive shaft and from the rear end knuckle. Gently prise the drive shaft from the two U-joint halves and remove from under the vehicle; set clear of work area. On some vehicles, you cannot remove the U-joint clamps from one end of the drive shaft, but this operation is still possible; it depends on your vehicle's configuration. Hopefully, you can remove the U-joint clamps from both ends of the drive shaft because this makes it much easier to remove the front yoke from the transmission. The front yoke just slips into the tailpiece drive shaft seal of the transmission and is held in place by the length of the drive shaft when completely assembled. Just pull STRAIGHT BACK firmly on the yoke until it comes out of the tailpiece drive shaft seal. It is customary for some fluid to leak from the transmission tailpiece when the yoke is removed. If your vehicle is a Four/All Wheel Drive model, repeat this operation AND Step Four for the transfer case and front drive shaft.
Seventh, remove the tailpiece mounting bolt from the crossmember under the rear of the transmission.
Eighth, remove the four bolts (2 on each side) which hold the transmission crossmember to the vehicle frame. DO NOT REMOVE THE CROSSMEMBER AT THIS TIME.

Bad oil leak by the starter on my 1988 chevy k1500 (305)


Could be the oil pan gasket or the rear main oil seal.
Remove the torque convertor cover. ( I am assuming that your truck is an automatic) That's that thin metal cover between the engine and transmission on the bottom side.
Drive the truck around the block to warm up and the oil to start leaking.
With the engine running in neutral, emergency brake on and wheels choked for safety.
Crawl under the truck and see where exactly the leak is. Is it between the flywheel and the engine block --leaking straight down the center of the flywheel --crankshaft rear seal?Or the pan gasket? or even a oil galley plug?
Good Luck.

Rear seat removal on 1988 full size 2dr chevy blazer


The rear seat is bolted to the floor either from the inside or the outside. If attached from the undercarriage you will need to locate the rubber plugs that cover the bolt head or the hex nuts to the seat. Just remove these and the seat will come out.

I cant get my starter back in


If you take the motor mount bolt out of the side the starter is on you can use a floor jack under the oil pan to lift the engine enough to get the starter in. You should put a block of wood or sometuing like it on top of the jack to protect the oil pan.
