You will need to remove the exhaust manifold retaining bolts in your 1993 Chevy Astro. Remove the exhaust manifold. Remove the exhaust manifold gasket and clean the surface. Reverse the process to install the new exhaust manifold gasket.
That would probably cause it to run lean.
It is inside the upper intake manifold. It is attached to the fuel injector poppets with a bracket. To inspect/replace you must remove the upper intake manifold.
I have a mid size RV that's shaped like a van in the front. The intake was removed. Is it hard to put back on.
I have a 97 Astro that is leaking. The dealer ship quoted a price of $650. minimum. I know there is a lower and upper manifold gaskets.I'm faced and with cruise control and fuel injection and I am a little aprehensive. But being out of options and low on funds due to uncle sam and cost of living increases and not alot of work I might have to take it on. Any help would be cool. I have been driving GM products for 30 years and have never had a intake manifold gasket blow.
Remove the cylinder had from your 1997 Chevy Astro engine. Remove the head gasket and clean the surface. Put the new head gasket on and reverse the process.
it is part of the fuel injector which is under the upper intake manifold
Depends on your location and labor rates. I would suspect ~400-600 for a private mechanic, more at a dealer.
Most all of the vacuum lines will start from the intake manifold in the rear..........
It took 4.3 hours
To the left of the water inlet housing (thermostat housing) on the intake manifold
No transmission drain plug. You have to drop the pan, then replace the filter and gasket.
The vents are controlled by vaccuum from the intake manifold. Check for a split rubber vac. hose on the manifold- Hope that helps.
Drop the lower transmission pan Clean pan Replace filter and gasket
If it has the 4.3 ltr engine, the intake manifold is notorious for leaking at the back of the engine where you cannot see it. Try using a mirror at the rear of the intake manifold and look for wetness. Replacing the gaskey is the best fix.
I did an intake gasket on a 2004 astro awd 4 month ago. It not that hard but you got to remove everything around of the engine compartment. It took me maybe 5 hours. U got to be a little flex to work with it . GOod luck
It snaps in. But before you snap it out, take the nut out that holds the pipe to the exhaust manifold.
The 4.3 liter Chevy Astro head gasket torque specification is 160 pounds. The head gasket bolts should be torqued in 40 pound intervals.
More than likely your intake gasket is at fault cusing the leak. This is common on 4.3 v6 engines.
Remove the transmission oil pan for access to filter Replace fluid, filter and gasket
On the intake manifold...check with a local parts store to see what a new one looks like first if necessary...Paul
i have a 2003 chev astro van and need to replace the blower fan
no heat and rising temp are simply a product of the coolant leaking (low). Most likely cause of leak (assuming all heater hoses have already been checked for leaks is the intake manifold gaskets. GM used solid PLASTIC gaskets on these motors with o-ring type seals around the ports and over time develop leaks between the cylinder head and intake manifold. A gasket set by Felpro is now made w/ steel inserts/molded rubber seals to rectify the problem. requires removal of intake manifold. I have done several of these with the same problem.
The MAP (Manifold Absolute Pressure) sensor monitors the pressure inside the intake manifold and sends that info to the ECM (Engine Control Module). The ECM uses that info and input from other sensors to make the engine run its best under all conditions.
You dont the seats that an astro comes with are just great
