Yes that could be a symptom of a cracked head or blown head gasket.

SOURCE: i have 1998 cadillac seville w/northstar motor

The most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.The hose goes in to the engine to a crossover and comes out the other side to near the thermostat housing,the blockage may be there.

SOURCE: run s hot.changed thermastat.still runs hot no

No water in the oil? How about oil in the water? When you fill up the radiator, is there a scum floating on the top? Look for steam coming out the exhaust when the engine is warm. A radiator shop can do a comp check and tell you real fast what is wrong. It sounds like a head gasket, Keep an eye on the temp gauge. One more thing is the engine could have air trapped in there, and it needs to be vented out, all cars are different, some have vents, some don't, some don't do it. Some need to be elevated to be filled, etc, check it out. Hope this helps.

SOURCE: my 98 chevy malibu is

If your engine is running fine with no miss in it possibilities could be radiator fan or water pump if the radiator fan is working fine it could be the water pump. I have seen a water pump after removing it where the fins on the pump were completely worn out causing the overheating.Let me know how this turns out for you thanks.

SOURCE: cracked head

Believe me, if you have a cracked head you don't want to know about it. The problem is most probably with the cooling system (e.g. a clogged radiator). That's the best I can do with the insufficient information you've furnished.

Oil is getting n my radiator it is a cream color & thick like a gravy, my truck hasnt been running hot until a few weeks ago due 2 it getting so thick and wont rotate, everyone says its a cracked


Sounds like you either have a cracked cylinder head, or more likely, a blown head gasket. Get the gasket changed, and have the head inspected and tested while it's off.

When the car is driven and motor gets hot the car shuts down but when it cools down it starts and runs fine again until it gets hot


IT is most likely the thermastat but i would not suggest driving it until it fixed as that could cause the head to crack witch costs around $213 - $250

Hello again
The problem here based on what you have told me is that you have a cylinder head gasket leaking combustion gas into the cooling system, this creates gas pockets around the thermostat and delays it opening. You can try adding one of the many head gasket sealers available in auto parts stores. I suggest you contact a local NAPA or Carquest auto parts store and ask what they think really works, I' heard that many do work but have no 1st hand knowledge. To make sure air is not in the cooling system do the following, you will need a floor jack. If the problem persists you will need the head gasket replaced and the cylinder head checked for cracks and if it checks ok then machined flat again.



The generic method of bleeding air from the cooling system is to use a floor jack and raise the front of the car as high as possible, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the system.

Ok i was goin down the road after leavin my buddys house and it ran hot but it will still start an run but it runs hot idk if it is my thermostat is bad or if i cracked my head or blown head gasket


to start with, i would remove the radiator cap from the yota, while its cold, run the engine up to normal operating temperature, if your thirmostate is functioning properly you should be able to see the flow. as for a cracked head or blown gasket, there would be other symtoms **** as coolant in your oil or vise versa,

Jaguar overheated, radiator cracked on warm water side, repaired radiator, start and test, running hot again, stopped, obtained new thermostat with relevant piping, old thermostat broken into 5 pieces,...


Jags are HARD to work on, and even HARDER to buy parts for ... so ... have you ever heard of K-Seal? If it WORKS, it could save you $1,000's! If it doesn't work, you're out less than $20!
