brilliant, the thermostat is backwards
Remove the water supply hose from your 1987 Chevy Astro thermostat housing. Remove the thermostat housing retaining bolts. Remove the old thermostat and drive in the new thermostat.
Look where the upper radiator hose connects to the engine. There you will find the thermostat.
i replaced the steering column and the fuel filter. the radio was stolen
Trouble code P0128 means:Coolant thermostat (coolant temp below thermostat regulating temp)
The PCV valve on a 1999 Astro should be located on top of the valve cover. It plugs in and can be easily replaced.
6 I just replaced mine same year.
Under the hood just follow the upper radiator hose to the engine and u will find it it has the thermostat under the alluminum base the is hold by two bolts..
if you follow the upper rad hose towards the engine, where the hose attaches to the motor it is under that housing.
The hottest they make for the 1993 Astro is 195 deg., so if you are lower then that you can put one of them in.
Where is the temp sensor on a 91 Chevy astro
The 1995 Chevrolet Astro and coolant temperature sensor can be found on the front of the engine. The coolant temperature sensor will be a few inches above the thermostat housing.
You need to make sure that your radiator fan is working properly. Some are fixed, some have a clutch that engages them when the engine heats up. Watch your fan when the engine is hot to see if it functions correctly.
