Sign of possible head gasket failure
Only if there is a problem with the radiator.
You use the coolent reservoir bottle to fill the radiator. It should fill the rad before it fills the bottle.
take the vehicle to a reputible radiator repair shop and they should be able to flush the whole system out for you.
Many VW Beetles from '98 to '05 don't have a traditional old-school radiator cap. The radiator fluid usually is poured into the radiator fluid recovery bottle. There should be a fill line on the bottle.
Stop leak products for the radiator from auto supply stores are not meant as a long-term solution. They should only be used to get you home or to a mechanic who can repair or replace the radiator properly.
Well radiator repair will depend on the damage or replacements needed to fix the radiator. Thus, no average cost is really available. However, if it is only minor repair I would think that it should only cost $50 dollars for parts and then whatever the repair man is charging for labor.
You should try to find out if you can repair it yourself. Most radiator problems are the result of impacts from road debris. If this is the case you may be able to repair it simply by yourself. You certainly don't want to delay. Repairing a radiator is simple and inexpensive. Not repairing it could lead to great trouble and expense.
Here is advice: * The best thing to do it to take the radiator to a repair shop and let them handle the repair. They will clean and flush it and repair any leaks. It may be almost as cheap to replace as to repair. Check on the price of a new radiator before paying for a repair. * Most modern radiators are aluminum and plastic composite. They are not economically repairable and therefore should be replaced. NEVER replace the radiator without new hose, new radiator cap and new coolant. A new thermostat is recommended. NOTE: Unless damaged, the chief cause of radiator failure is actually a blown or leaking engine head gasket allowing the cylinder pressure (80-125 PSI to leak into the radiator (max 20 PSI).
According to the Haynes repair manual for Chevy/GMC trucks 1988 thru 2000 the cap should be a 15 psi radiator cap.
check that the radiator hoses are not soft with engine hot , squeeze hose with your hand you should have strong resistance in hose if they are good other thing is to not fill radiator thru radiator, but to fill thru overflow bottle
Qualifications a repair technician must have is a state board certified licence say that the technician has the proper school and work experience to do a major repair.
Repairing radiators has gone out of style. It is cheaper to get the parts rather quick.
