There are many possibilities for car overheating. But as per what you have mentioned in your question ,You have ruled out most of the possibilities by replacing the possible parts for overheating. But one thing is very common that coolant is leaking.And this is the reason of car overheating.If coolant is leaking then you replace all parts the car will overheat till the coolant leak is not stopped. It must be leaking from under the valve cover.''the timing cover is leaking coolant''--engines water pump is behind the cover and it is failing.Other possible location from where coolant can leak are, timing gasket $40, valve cover gasket $140, oil pan gasket set $70, and coolant flush pan. It has to be checked at every location and the leak has to be stopped.Also you can get the coolant pressure test done.With that the exact position of the leak will be identified.At local car auto stores they conduct coolant pressure test.Its not too costly.  Other possibilities for overheating are :-- Overheating can also be caused by an overly-lean fuel to air mixture, or overly advanced ignition timing. Check these or have them checked. This should be part of any major tune-up.

Your water pump may have gone south, as well, which would mean coolant isn't circulating through the engine. And not to sound patronizing (I don't know the reader's level of automotive knowledge) but just to be thorough, if the water pump is belt driven, the belt might be loose, broken or missing.
Lastly, and worst, one or both of the heads or the block might be cracked, or the head gaskets might be blown.
Any overheating will lead to loss in power, as the engine is just not designed to run at such temperatures. The last and worst case, though, will cause severe and increasing power loss.
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

88 dodge chadow,overheating and no heat


How long has it been going on? You need to check if you have a bad head gasket. A compression test of the cylinders would tell you. Not saying that's what it is, but that can be a cause of overheating. And it can also be an expensive result of prolonged overheating. That's why mechanics caution against running an overheating engine. If you find the head gasket is good, it will give you great peace of mind, knowing the Shadow's engine warrants a few more dollars in repairs. Compared to the cost of a new head gasket and having the head checked for straightness and for cracks, other repairs for overheating is minimal.
First check the coolant level and keep it full. It could be a worn water pump. Feel for pressure behind the coolant when you squeeze the upper radiator hose for a second or two. The engine needs to be warmed up and running, so the thermostat is open. Try to squeeze the hose closed, then let off and feel for a surge of coolant, and watch the coolant in the radiator for pressure pushing coolant on through the radiator. Kind of a rough test if pump is circulating coolant. You might also try a new thermostat. They are cheap and easy to replace. Clean the outside of the radiator of leaves or dirt. It should be checked for blockage. When upper hose is hot, the lower hose should also be hot or quite warm, just not as hot as the upper hose. If it is, radiator seems not blocked.
Don't worry about having no heat at this time. When the overheating is solved, and coolant level is full, the heater will return.

How do I change a thermostat in a 2001 New Beatle VW


First you should drain the antifreez by opening the drain plug located by the lower radiator hose. Then take the upper radiator hose off. Then take the 2 bolts out that hold the housing on. Remove the housng and there is your thermastat. Accordind to VW they want you to put antifreeze on the o-ring I use RTV a little extra help sealing just don't put a lot on. The book says to put thermastat in housing and turn 1/4 turn to right. I'm not sure why but thats what it says. TIP If you close the drain plug now and put as much antifreeze in as you can makes it easyer to get air pockets out later. Mount your therrmostast housing back to block and tighten bolts. Again put as much antifreeze in that you can them put upper radiator hose back on. Again put as much antifreeze in that you can. Now come the hard part sometimes getting all the air out of the cooling system. Put the radiator cap on but loose run the engine till the cooling fan kicks on but keep checking the coolant level. WARNING ANTIFREEZE WILL GET ABOVE 200 DEGREES
both upper and lower radiator hoses should be hot and radiator full. If both hoses aren't hot you have an air pocket that you have to get out. To do this run the engine a couple minutes after the fan kicks on then turn engine off for 5 or 10 minutes and start over keep doing this till both hoses get hot and the air the fan is blowing is hot. Once this is doe yout ready to go. I hose off any antifreeze that got one car so if you see antifreeze under car you know something is leaking and not what was spilled. 254a047.pnga06a9b1.png

How to change thermostat


Hello Friend:

Your Thermastat is located in a Dome Shaped Housing,just take your hand put it on upper radiator hose and follow it to the engine ,you'll run into a hose clamp around the hose thats holding it on the Thermastat Housing.

Make sure your car is cold, then put a pan underneath vehicle below the thermastat housing,You'll loose a Little Coolant ,So this Way you can catch it.

Just Loosen the Rad. Hose Clamp and Pull off the Hose from the Thermastat Housing.Then you'll have a couple bolts holding on the Housing,Remove the Bolts and The Housing should be FREE to come off.If its a Little Stubborn ,Lightly Tap on It with a Plastic or Rubber Hammer a nd it will come off.Your Thermastat is under the Housing.

After off Clean Both Surfaces on the Housing remove All the Old Gasket material and Gasket Sealer .Then just put your new thermastat housing in with the Spring part facing Up.

Put Gasket Sealer on The Thermastat Housing and Put new Gasket on and Line up your Bolts Holes.

And Also piut a Small bead og Gasket Sealer on The Engines Surface. Tighten Down Good and Snug ,But Don't Over Tighten.

Put the Hose back on Tighten Clamp and Fill Radiator Back up to Top.

Need to know how to replace thermostat


Hi: You'll first want to Drain your Radiator take your radiator cap off so when drain it the coolant will drain freely.Then Drain your raditor you'll find a Drain Tee outlet on the inside bottom of your radiator. And catch the Coolant in a Drain Pan. Standing in Front of your Vehicle you'll see a Hose connected to your Radiator(UPPER RADIATOR HOSE) take your Hand and follow it down to your Engine until you locat a Hose Clamp Remove the hose clamp and work off the top Radiator Hose.Where you removed the hose theres a Dome Shaped Metal Housing,with 2 bolts in it. Take those 2-Bolts out and Remove the Dome Thermastat Housing,Under it You'll Find your Thermostat it shuold come out with a little Resistance. Once its out, Clean Up The Thermastat Dome of any Gasket still left on it, and clean where you remove the Thermastat Surface.To put back just Reverse the Removal Be-sure your Thermastat is put in right and not up side down.Then get some Gasket Sealer Put a Little on the Thermastat Housing where gasket goes and some on the Enging surface and Install your New Thermastat,Be careful when Tightening the 2-Bolts on The Housing. not to Over tighten them.The torque Specs on the 2 bolts range between 10- 15 Foot pounds.You don't want to Strip,
After you get your New Thermastat in and your Radiator Hose on and Clamped.Make Sure you have closed the Drain outlet. then fill with coolant,if your coolant is old i recommend putting new coolant in. I hope this helps You.I;m Sure it Will, But please let me Know through FIXYA by Voting and a Testamony.This way I'll know that my solution was Helpful. Thanks From d_hubbs

How to replace a thermostat on a 1987 olds delta 88


follow the radiator hose on the top of the radiator to where it goes into the top of the engine. remove the clamp connecting it to the engine. you will need to set a bucket under car if possible. you will loose about a 1/2 to 1 gallon of anti-freeze. there will be two screws holding on the nipple the hose was clamped to. remove those two bolts. your thermostat is now visible. when replacing be sure to get a gasket or it will leak.
