I have a 1996 Jimmy, so my answer is based on that. Plan about an hour for the thermostat, and another hour for a cooling system flush, if you decide to do that part. You'll need the following: 1) Thermostat 2) Dex coolant 3) A closed container for holding drained coolant 4) Cooling system flush 5) RTV sealant...maybe (keep it pn hand just in case 5) 3/8" drive 10mm and 12mm deep socket,and a 3/8" ratchet 6) extension bar 7) 10mm open ended wrench 8) 1/2" deep socket (I may have this size wrong) 9) Good music (optional)
I will assume you know the location of everything.
- Take the air intake cover off. - Remove the two brackets which hold the throttle wires. - Remove the two bolts securing the thermostat housing. - Lift the housing and move out of the way. - Remove the thermostat. Sometimes they need a little encouragement. If it remains in place, remove the rubber gasket from the engine. Be carefull not to mar the metal, or get any gasket material in the opening to the cooling system. Stuff a rag into the opening if need be. - Put the new thermostat in and reattach the housing. You need to torque the bolts down with 18 ft. lbs. of pressure. You can borrow a torque wrench at most auto stores for free or cheap. - put everything back together. - Flush cooling system, if you want. - Refill cooling system with extended life Dex coolant. *DO NOT ADD WATER* - Run the engine for a while to be sure it all worked out okay.
I PROBABLY MISSED A STEP OR THREE! Get a good manual (I use Haynes) and read it thoroughly before starting a project like this. It will be well worth the time...trust me.
Don't know what year you have but some sensors are temperature sensitive and you should run a 195 degree thermostat.
remove the intake hose and the exhaust port screwed into the egr valve, the remove the two retaining bolts from the intake and clean any old gasket material away. if possible run a piece of wire down the hole to make certain the passage is clear of carbon build up
It should be on the front of the intake manifold directly above and behind the water pump.
Yes it will bolt right up to it.
There is one before and one after the catalytic converter.
43L of 18-k gold
The fuel lines around the filter; you will need an adapter.
Clockwise, 1, 6, 5, 4, 3, 2.
There is no adjustment required, but you can clean it with a carb cleaner.
Use an exhaust made for an LT1 engine the blocks are identical it is the insides that is different. Will bolt right on.
sounds like a vacuum leak
all distributors have some kind of centrifugal advance, you will be able to see if you take the distributor cap and rotor off. have a look at the base plate to see.
You need a special tool, a harmonic balancer puller. Go to Autozone and they will usually lend you one for free. VBD
The EGR valve on your Astrovan is on the backside of the intake manifold just under the throttle body attached by two bolts. After installing a new gasket be sure and torque the BOLTS to 17-18ft lbs or the NUTS (if yours has studs) to 15ft lbs)
0 degrees,should say right on the fan shroud on the same sticker that tells the spark plug gap. In order to time it correctly you must unhook the esc electronic spark control wire which is a tan wire with a black stripe located under the black cover on the passenger side firewall. It may set off a service engine soon light. When your done timing it unhook the battery cable and the light should go out.
What year is the gtp, if 95 or newer yes, if gtp is in the 80's then no due to pollution restrictions today, and may have to change the computers from each vehicle. Each computer is set to specs for the engine it controls.

sounds like an earth problem to me, check and clean all your earth points though i suspect its more of an earth failure
E`bay --Ebay motors ,,search chevy, blazer s10, I have found and seen motors as low as 600.00, for blazers,If you can`t find it let me know and i`ll find the e`bay store and let you khow what it is.. Jasper engines are the best rebuit engines that I have seen and have a backed up warranty. I'm sure there is a dealer near you that installs them.
I had the same thing happen on a trip to Florida this past fall. You have a broken vacuum line. Take the doghouse off and on either side of the intake manifold you will see a vacuum port with multiple lines coming from each. One side is for power assisted brakes, steering etc. The other side is for vacuum control of emmissions and air dampers of the heating/air-conditioning ducting. Trace out these lines and I am certain you will find one broken. Replace it and you'll be good again. Agreed, mine seems to go out every year, but it is an easy fix. I start looking under the hood on the pasenger side right behind and to the left of where the air conditioner connections are.
I have a '90 so I think it would be the same, on mine it is at the front of the engine on the bottom pulley. (crankshaft pulley or vibration dampener) To view the scale and mark I have to look down, a little on the drivers side of center. Beside the break resivour is a good viewpoint, looking just over the timing light. I have to run the timing pickup coil in through the drivers door or window and into the open doghouse cover. Good luck. God Bless!
