Most likely it will cause overheating. The system uses pressure to raise the boiling of the coolant. Boiling coolant does not cool

Replaced radiator thermalstat cap it still overheats

Hi Donald it could be air in the system, or a crack in the EGR cooler. At worst it could be a head gasket problem or even a cracked head. You will need someone to look at it to confirm for you either way. Regards Jim...

Temperature normal but radiator bottle boiling in my golf 4

If your radiator coolant is boiling then do not drive as your car could/will overheat and cause some serious damage

The temperature gauge in the Mk4 Golf is'nt that accurate, it will usually stay in the middle until you've got a major problem, where the coolant is boiling and expanding so if it's just slightly overheating, the gauge could show as normal.

The problem could be caused by numerous things such as a leak/crack in the coolant system and isn't pressurized such as a faulty coolant bottle cap not sealing properly, could be a problem with the fans, or and issue with the temp sensor /thermostat can cause confusion. It's hard to diagnose without seeing. I would take it into a garage for further inspection.

check for low coolant level make sure coolant system been bleed from air.make radiator full coolant and coolant reservoir on the full cold mark.if all is good the cooling fan relay could be bad or the engine coolant temperature sensor could be faulty.

Antifreeze backing up into overflow

Your radiator cap may not be holding pressure, or there may be a head gasket failure that's allowing compression pressure to get into the cooling system. The overflow is supposed to have *some* coolant backup in it normally; I assume yours is pushing a lot of coolant into the tank. That's usually a sign of a blown head gasket (and sometimes a cracked head), which is distressingly common on these at high mileages - particularly when the radiator fan connector burns out or the intake gaskets have failed and let the coolant escape to cause an engine overheat.

90 Cherokee inline 6 pushing fluid out of overflow bottle at cap no cracks and not overheating does it a couple of min. after you start driving

I think the seal under the cap is bad. Try replacing it with a new cap. Overtime these will not hold pressure, causing fluid to flow out. Sometimes it will run hot, other times it will be fine.

Will a cracked overfill bottle cause my jeep to overheat.

If you have a closed system (no cap on the radiator, fill cap is screw type on the tank) Yes it will cause an overheat.
It is possible to overheat due to a broken recovery bottle in a normal system but usually it takes a long time as very little coolant is lost and generally it can run with nothing in the bottle for a month or more without problems. In any case you can obtain one for either system very cheap at any local scrapyard.

1994 gmc sierra 4x4 350cu inch auto trans engine coolant gurgling started gurgling after water pump was replaced replaced waterpump with gm oem then replaced heater core then replaced head gaskets still...

I have seen this many times before. The sound is air being forced out of the radiator cap and escaping back into the coolant recovery bottle. It can be as simple as a new radiator cap or as costly as cylinder head crack, or even block cracked. It is important that your radiator be completely full with proper coolant mix and have a good working order cap with the proper pressure.
