Engine is Overheating?

If it gets to hot it will shut down as a safety precaution. if it overheats quickly it cold be a bad tstat,if it takes a while it would be several things. when hot check rad for cold spots by putting hand on fins, make sure fans are inoperative. then have it pressure checked, you may have a head/intake gasket problem.

Have the tests done below and try bleeding it again

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

Bleeding it

Always bleed air from cooling system after replacing coolant. Set heater for maximum heat. Remove radiator cap. Loosen drain plug and remove drain bolt (if equipped) from engine block. Drain coolant reservoir. Fill coolant reservoir to MAX mark with 50/50 water-coolant mixture. Loosen bleed bolt and fill radiator up to base of filler neck. Close bleed bolt when coolant flows out without bubbles. Tighten bleed bolt. With radiator cap removed, start and operate engine to normal operating temperature. Add coolant if necessary and check for leaks.

Check fuse no.39/40 30amp

If the cooling fan don't come on time it will cause the engine to overheat-you need to check and test the fan motor, fan relay, coolant temperature sensor and the computer if its not turning on-

Have you seen any white smoke from tailpipe? Also check oil if it looks like a chocolate malt? If yes then probable head gasket failure.

You will need to find a shop that can pin point the leak and diag the fan problem. The to problems may be related. Did thay do a pressure test on the cooling system?

It sounds like a water pump. If it is, the pump is about 89 and 1.2 hours for laboe

the other possibility is the lower intake. Thats around 800-900.

You need a new shop with proper equipment to accurately diag the problem correctly.

Have coolant system pressue checked for an internal problem like a head gasket. Also check t stat and radiator for cold spots. When hot. With engine off and fans disabled.

The easiest way to determine the source of the leak would be to fill cooling system and put a pressure tester on it. Pressure testing the cooling system pushes air into the system and can show you where the leak is at without having to run the vehicle. I would sugguest not driving the vehicle with a coolant leak, because overheating can lead to more costly repairs.

Any of dozens of different causes. You need to refill and pressure test the system to find any leaks. It may not have been completely filled when it was repaired as this system is prone to air pockets. You also could have head gasket damage from the original overheating.

Good evening.

The A/C system should trigger the fan when the pressure in the A/C system reaches 150 lbs.

The cooling fan should come on when the temp reaches 215 degrees.

The simple way to check the system is this key on engine off, remove the wire connector from the coolant sensor on the intake. The fans should kick on. That will check the entire circuit and controls for the fans.

Start there.

Yes, I also believe the thermostat needs to be changed yes, it is a pain but must be done.

No, do not throw relays and fuses at it at this point. Lets find the root cause of failure.
