HOW TO ADJUST VALVES ON 2006 CHEVY EQUINOX 3.4L

Those are not needing adjustment intervals, also you should be equipped with VVT (variable valve timing) Are you hearing top end noise at idle?

Check or replace the thermostat, if still running hot check fans, fit pressure gauge to radiator to check for head gasket compression leak.

Head gasket

Just a possible "heads up" on this;

There are numerous complaints about the Chevy Equinox heating up and then not starting. This has been a known issue with these trucks for years.
According to the most common discrepancies, the heads heat up due to a faulty head gasket.
In many of the cases, the heads "warp" from the overheating, which could result in a major repair typically $1,500 - $2,000.
You can Google "Equinox Got Hot and Won't Start" and you will find hundreds of cases.....but most of them were caused by faulty head gaskets.

As you know one of the problems can be the Fuel Cap. I make this suggestion. If you changed your Fuel Cap before the Purge Valve double check that the cap used was an OEM (Original) Chevy Part for that specific vehicle, not just any cap from another Chevy.

Thermostat, cooling fan or head gasket. I need more info.

Coolant level full? Rad fan operational? Possible defective thermostat. Worse case plugged rad or head gasket

There is a few things that could course your car to be over heating

• Air In Cooling System
• Coolant Leak
• Water Pump Failure
• Head Gasket Failure

These are some of the common problems as your car is reasonable new i would't think the head gasket has gone it is more then likely what you say that the water pump is broke probably the impaler has broken off. To bleed the system you need to get it up to running temperature and remove the bleed screws in the cooling system starting from the highest one working down then back up. If you find it is hard to bleed and no coolant is being pushed out it is more then likely that the water pump has gone. To test if the head gasket has gone take off the oil cap and look for a mayo type gunk around it if there is then this means that water is getting into the oil system meaning the head gasket has gone another test is to use a spacial liquid that test for exhaust gases in the coolant system.

drop tranny pan.which will drain fluid. replace filter, gasket then pan refill with fluid .start and let run a few minutes then put in gear it may take a second for fluid to get all thru trans that should do it
