When in doubt, throw it out. If there is any doubt the thermostat may be bad, just replace it with a new one. If you insist on testing it, you can drop it into a small pot of water and heat it up on the stove. A 195 degree thermostat should open just before the water boils.
Yes,
1992 Chevy s10 jumps out of 5th gear
No carburetor on that 89 S10. It would be throttle body fuel injected.
Check under the hood for a broken or disconnected vacuum line.
The 89 model does not have a VSS.
If you're thinking of a fuel pump inertia kill switch, the 89 S10 doesn't have one.
It cost about 10 bucks at any auto part store.
check the timing,if its like my 89 v6 was,there's a connector on the passenger side firewall that has to be disconnected before adjusting the timing.
under the dashboard on the passenger side. take the kick panel out and u will see it
A vacuum leak would do that. Check the base gasket under the throttle body.
# Turn the wiper on # Check it # You're finish, now enjoy the day with ice cream :D
Do this when the engine is cool. Use an appropriate container to catch any coolant spillage. Then take the thermostat cover off, take out the old thermostat and clean up any rust or sealant residue. Put the new thermostat in with a new gasket and put the cover back in place. Refill the radiator with coolant and check for leaks.
