Engine overheating

Thanks for the guides I found the water pump was leaking so I got a new one for $114.00 and fixed it I love this site.

Engine Cooling problem
2003 Chevy Blazer 6 cyl Four Wheel Drive Automatic

this vehicle has an issue with running hot to the point of boiling in the coolant resevoir. They have had a new radiator and thermostat installed at a shop. I have drained the green coolant out and installed the dexcool coolant, also I have replaced the fan clutch. The temp at the thermostat housing after driving is 220 and the temp guage agrees with that. I am just wondering what im missing. Also, while driving there is a "gurgling" sound during acceleration coming from the heater core area, and I was very careful to make sure there was no air in the system. Or so I thought.

Hello,
I have a great little blazer that is still my favorite to drive but it is runnig screwy and I need some hints.

1. Everyday I have to add water to the radiator always 16-32 ounces. I don't drive far 20 miles round trip.

2. When I stop at the lights the car shudders and feels like it misses.

3. It runs fine down the highway but in slow moving traffic it boggs down.

4. It over heated today Tuesday the 22, First time in over 16 months.

5. The thermostat is fine it was wide open when the mechanic to the assembly apart. It collapsed in mere seconds after being exposed to the cooler envionment.

6. I have 20w-50 synthetic with a Lucas additive just changed 4,000 miles ago. I used the Fram exra guard filter. Today when I checked the oil it was milky, looked like coffe with creamer in it. Very upsetting but not the end of the world. I will change the oil tomorrow, but how will this affect my lifters? What is my potential downfall here.

7. The mechanic shop said "I have a blown head gasket and it will be a three day job costing 1,500 dollars. Wow to my supprise I figured bad water pump something simple not a head gasket.

8. What kind of test can be run to diagnose the problem properly? I do not wish to just give money away to people. If there is a 100 dollar diagnostic test that can be run I would prefer that. Is there really a way to deterine if it is a head gasket or are you supposed to take the at their word. Economics being what they are now can you really take someones word when the overhead is so high and the revenue so low?

9. I hope this is not too much information but I figure the more you know the better the guess. Thank you for your time.

Just a little help for the uneducated in car lingo. What is the differance and how do I sound like I have a clue? Is the Head Gasket failure rate common along with the Intake Manifold Gasket. Where is this located and what type of repair is it in relation to the head gasket? I am confused. Can this be fixed and then have the head gasket go son after because now there ismore compression and it will seek a ne weakness?

A month ago my engine began to overheat. It never reached red line because I pulled over and let it cool before it did. When I opened the hood the reservoir had a brown gunk in it. So I got my radiator flushed and filled with more DexCool coolant. That fixed the problem. Now fast forward to now. The car is starting to run hot (3/4 of the full temp guage) when the car is at a stop light or in park. When the car is in motion, at all, the temp. Goes back down. Also when the car is accelerated there is a water flowing/bubbling noise that can be heard. I don't really know if it is getting hot though because when it gets hot I'll turn off the car and listen and there is no classic hot water bubbling noise nor smell or steam. I think that it needs a new water pump. What do you guys think?

Thanks for your time and answers. Where is this intake manifold gasket located? How do I direct the mechanic to observe the failure possibility of this particular gasket instead of the head. Can the manifold be removed without compromising the integrity of the seal? Can the head be removed with out ruining the structural integrity of the head gasket? Can they the machanics do a gasket check or compression check to determine which specific area is damaged and replace that gasket? I appreciate the fact that you have never gad one go bad.

Mine is doing the same thing. I've noticed too when it overheats I lose all heat to the interior compartment.

My Radiater has coolant in it.(When engine is cool, I remove radiator cap and liquid is to the top). However the engine is overheating on me this afternoon. I do live in Phoenix, Az and the current temp is 112. Any suggestions. I do have an appointment set to look at it first thing monday morning.

I am takign it to a shop first thing monday to have them look at it. I trust these guys my brother has used them and they are nice. I have talked to someone else about this and they agree it might be the thermostate. I have read its and inexpensive replacement plus labor might run me aroud 75. Does that sound about right. I hope that is the issue. I just put new tires on the fron this morning I dont feel liek dumping alot of money into it. But it does get me around and I do need it.

What causes the s10 blazer to boil over into the expansion tank?
