My 350 chevy engine has been bored 10 thousands and I have it in a1960 chevy pickupand it gets hot setting at an idle. Have put a new 3 core radiator on it and also have an electric fan

Dear Bobby,
Here are some ideas for you.
You might want to start by asking some mechanics if they think there is something wrong inside the engine causing your overheating.
If so, something may be failing, like bearings, or perhaps there is a tiny crack.
If they do not think so, here are a few other items.
Some people might try a heavy duty water pump.
Some try adding yet another radiator for more cooling. ( I have seen some mount another radiator in the truck bed, my next door neighbor did.)
Be sure your lower radiator hose is not sucking together.
Sometimes the coil spring inside the hose can slip or rust leaving a section of the hose to collapse..
You might not see this happening unless you looked for it.
Be sure your water pump/fan belt is not slipping.
Be sure your engine block is not rusty inside.
God bless your efforts.

A/C recharged and thermostat replaced, now engine over heats in first 20 minutes of use. After 15 minute "cool down", engine runs fine and in normal temp. zone.

check that there is no air lock in the cooling system
check if the thermostat was installed with the body of the unit facing the block and not the hose

Install the thermostat and fill and bleed the coolant sys

Thermostat can only go one way,toward the intake/block/
motor etc

You leave the filler cap or rad cap off, until the thermostat
opens, then replace it & overfill the coolant or degas bottle
an inch or so

Which direction does the spring go when installing the thermostat? In to the block or out to the hose?

The spring side noramly goes down to the block side. It is senceing the block tempature not the radiator tempature becase that changes to cool the engine tempature and the spring is what is called bimatlic so its tempature sensitive and looses tenistion the hotter it gets to allow more coolant to flow from the water pump through the radaitor to the engine block to cool the engine

I have a 1997 Chevy Blazer that is overheating and is leaking coolant. It is not the rad hose because I have already checked that. It is a part that is attached to the engine block, directly above the...

Ihave a 96 s10 lt blazer First of all the steering coloum is now where near the engine block and the bracket you mention is for the throttle cable and the cruise control cable and has no gasket for any kind of a seal with the intake manifold. The 4.3 and most chevy engines have a problem with the intake manifold gaskets if you are over heating then likely the intake manifold gasket is leaking you should check your engine oil for antifreeze that will look like a fomey white yellowey residue and also check the radiator for engine oil floating on the top under the radiator cap. This is a big problem with chevy you can't let espesecly the 4.3 ever over heat.There is olny 8 bolts that hold the manifold to the block and there all in the four corners nun in the middle Y ou can save the engine if you fix it now but it is the intake manifold gasket that is leaking

What is the part that the actual thermostat sets in on a 93 honda accord 2.2 engine. Not the housing where the hose connects to. The part that the housing bolts to.

the engine block, I believe. REMOVAL & INSTALLATION
  1. With the engine cold, drain the cooling system.
  2. Disconnect the radiator hose from the thermostat housing outlet. Fig. 1: Use a pair of pliers to compress the spring clamp, then slide it up the hose and disconnect the hose from the housing 86803039.jpg

  3. Remove the thermostat housing outlet and remove the thermostat. Fig. 2: Remove the nuts/bolts securing the thermostat housing . . . 86803040.jpg
    Fig. 3: . . . then remove the thermostat housing 86803041.jpg
    Fig. 4: Once the housing is removed, the thermostat can be removed from the engine 86803042.jpg

  4. Using a putty knife, clean the gasket mounting surfaces. NOTE: If the thermostat is equipped with a pin valve, be sure to install the thermostat with the pin facing upward. To install:
  5. Install a new thermostat the gasket, O-ring or sealant (as applicable). Always install the spring end of the thermostat facing the engine.
  6. Tighten the thermostat cover-to-thermostat housing bolts to 9 ft. lbs. (12 Nm).
  7. Connect the radiator hose to the thermostat housing.
  8. Fill, then bleed the cooling system. Check for leaks.

Is it easy to replace the thermostat on celica 94''GT

Yes, Drain the cooling system to a level that is lower then the lower rad hose and where it meets the engine at the thermostat housing. Disconnect the cooling fan switch at the housing and squeeze the hose clamp flanges together to remove the radiator hose from the housing.Then remove the retianing nuts from the housing cover. Once removed note the position of the air bleed valve of the old thermostat while in the housing (bleed valve hole is normally on the top /facing up) Pull out thermostat and gasket. Note that the rubber gasket fits over/around the edge of the thermostat. Replace with new thermostat and gasket making sure the air bleed valve is in same position as previous and spring end is directed into the engine. Install the cover and bolts and tighten/torque accordingly. Reattach the hose to fitting and tighten hose clamp and reconnect cooling fan connector to end. Restart engine and allow to warm up sufficiently and check for leaks and heat in cabin compartment. Done. good luck.

Thermostat will not open

If the top radiator hose is not getting hot you know the coolant is not passing the thermostat. The last gentleman to answer you is probably correct. The thermostat must face the correct direction for the hot water to open the thermostat.

1996 chevy corsica 2.2 liter engine. Coolant temp never reaches above one-quarter hot, therefore no heat. I've put in four thermostats, installed new radiator, disconnected the cooling fan, still no heat....

You may have a stopped-up heater core. It's a little radiator inside your dash; it's where the heat comes from. I don't understand why the temp gauge isn't reading any higher than that...
