Question about Cars & Trucks
Engine losing coolant, no leaks, no symptoms of head gasket issues. Recently had the water pump and cam belt changed. Loses 1" of header tank per week.
I would check all hose clamps,tighten to make sure,check for signs of antifreeze.Crawl under and look and check for coolant.Check floor board for wetness.Is there any fluid coming from tail pipe?

ok, its time for a radiator flush. there is major sludge in the internals of this radiator. Make sure the thermostat is in the correct position as well. I've seen many cars come into my shop with the thermostat inserted backwards.

SOURCE: 99 deville head gasket leak?
A head gasket leak is usually indicated (among other things) by continous overheating of the motor, and subsequent loss of coolant.
It can also be indicated by the presence of engine combustion gas bubbles in the coolant resevoir.
Ensure the coolant system has no external leaks, such as faulty hose/s, radiator etc.
Ensure motor tune or other motor mechanical condition is not the cause of overheating.
I assume the motor is actually running hot.
Check cooling fans are operating ok (as necessary when car warms up):- if not check
2) relay operation,
3) heat sensor switch.
Check/replace the thermostat,
Check the coolant pressure cap is serviceable & of correct rating,
Ensure cooling system is correctly filled, bleed off any airlocks as necessary when re-filling,
Ensure radiator hose on suction side of waterpump is not collapsing at engine revs above idle (due softening),
If the motor has been severely overheated, the head gasket could be blown - look for combustion gas bubbles in the coolant resevoir.

Testimonial: "thx..my car is not overheating.only had to pull off road once.it does get to 233 sometime."
SOURCE: Mitsubishi L200 overheating
i have an l200 animal, i started getting the same symptoms, bubbling noises, over heating, water being discharged into the header tank, i had a good look around the engine,there was no oil in the water or water in the oil ( signs of head gasket failure) when the radiator cap was off and i revved hard nothing happened, no dip in water levels and no splashing out. i took the water pump off and the impellor had sheered off the shaft. fitted a new pump and its been fine, maybe all these cracked cylinder heads and warped heads are to do with the engine being run with the fault not being cured.
