My Isuzu pick-up has begun boiling over into the recovery tank even though the temp gauge does not indicate it is overheating. What would be a likely cause of this? The thermostat seems to be operating. I can see the level of coolant drop in the radiator with the cap off after letting the engine run.

The cap is brand new. I replaced it as the first thing. The flow into the recovery tank is VERY agressive but it does not smell hot.
Yesterday when I checked the coolant level in the radiator it was very low. I had to add a gallon of coolant

How much will it cost to fix if the head gasket is blown?

bad radiator cap...you are not getting the correct pounds of pressure from the cap.....replace the cap and the problem will go away

in the time of your holiday up the canyons your motor vehicle heated up and boiled because there became air contained in the cooling equipment. Coolant lower than pressure can keep up 245/250 ranges 50/50 coolant to water blend at 14 psi. Air compresses and the pocket of air contained in the cyl. heads of your motor vehicle's engine when you turn it off motives the boil. It took quite a few, warmth up and boil out to suck in adequate coolant and expel the air. Your doing top purely keep the tank on the completed line. no longer understanding what buick the three.8L engine thermostat housing has a bleeder for air on it.

Try flushing the cooling system. Sometimes, the flow is blocked just enough to back up into the recovery tank. The reason why the level of the cooloant dropped is partly because it went into the recovery tank!

If the radiator cap doesn't fix your problem...it's possible that you have a blown head gasket that's pressurizing the coolant system.

Are you sure your coolant is BOILING over? It is normal for coolant to expand into the recovery tank as the engine warms to running temperature and, conversely, to contract, or suck back into the engine, as it cools.

If there is no proper outlet from radiator or less outlet due to
inbuidwater pump defect or lesser efficiency, excess water will flow
to reserve tank due to accumulation in top portion of radiator.

I agree with your first answer, Bobsled. You can pick up a radiator cap at any type of auto parts store, like Auto Zone or Hi/Lo. Best of luck to you..........

put a new cap on it and do a routine flush and fill with right amount of antifreeze and water and that should solve you problem
