chevy s10 over heat

Question type: Maintenance & Repair

So my chevy just started over heating and the coolant isn't cycling. I replaced
both the thermostat and the water pump but to no avail.  The heat also doesn't
work. Don't know if thats related.

If those are the only parts you replaced your engine is most likely air locked. You need to see if there is a small bleeder screw on the coolant system somewhere or pull the thermostat out and fill the engine until the fluid will immerse the bottom of the thermostat then re-seal. If the thermostat doesn't contact the hot coolant in the motor it will not open until well after your engine has overheated, air is an insulator. Once you bleed the air out or get the hot fluid to open the thermostat the pump will use fluid from the rad, top it up until full then the reservoir will maintain the system. I leave the rad cap off until the thermostat opens and the fluid level stabilizes.


I will give this a go and let you know. thank you for responding.


I was having this issue with my S10 and it was fixed by flushing the entire system (after changing thermostat, thermostat housing, upper and lower hoses) I then replaced the coolant with Green coolant. The red coolant does more harm than good.
