Head Gasket

[Roy]

Try taking the truck to Phil, Lots of people have been taken at Foss.

If you have a suspect area you can try talcum powder or chalk dust . dust area then after running see if it has damp spots or seepage paths ( don't use flour or corn starch as they will burn)

head gaskets are not common on these trucks. i have worked on these trucks for a long time now and i have never done one for a coolant leak. I worked at the dealership for years and now i own my own shop. i would be happy to look at it for you if needed. thanks

Nice!



I wish we had a shop owner in Alberta as part of the club!

WOW!!!!!



You guys are truly a great group of people.

Thank you Thank you.

I have not taken it in yet. I live in Haliburton and the only thing I seem to do is work..... does not seem like I am any richer. Oh well.

I may take the truck into Master Mech. in Brampton is that where you are from ( the last e-mail )

They seem like a good and honest place.

Well it will be in a couple of weeks because I have to go to the armpit of America ( Buffalo )

just kidding if there are any Buffalo residents on the list.



Thanks again everyone

Hi Paul, a little late to the party here but if you still want to try the DIY route then this is the checklist you want to refer to... it should cover every possible scenario for loss of coolant! On my H3 recently I was losing coolant reeeaally quick and I couldn't figure out why, long story short I didn't tighten my rad cap (cross threaded while tightening by mistake) and was amazed just how fast I lost coolant. So in my experience even a small problem can manifest as a large loss of coolant! Hopefully this checklist is helpful for you.

Inspect the coolant level.



Is the coolant at the proper level?







Fill the cooling system to the proper level.







If the engine is suspected to have a coolant



leak into a cylinder, the coolant can



hydraulically lock the engine.



Does the engine crankshaft rotate?







Engine overheating can cause a loss of



coolant.



Is the engine overheating?







Extended operation with a low coolant level



can cause engine internal component failure.



Is the engine knocking?







Is a heavy white smoke present from the



exhaust pipe?







Does the white smoke have a burning coolant



type odor?



· Coolant in the exhaust system creates a



distinctive, burning coolant odor in the



exhaust.



· Condensation in the exhaust system can



cause an odorless white smoke during



engine warm up.







With the engine idling, inspect the coolant



recovery system.



Does the coolant recovery system discharge



coolant while the engine is idling?







Visually inspect the hoses, pipes and hose



clamps at the following locations:



· Coolant reservoir



· Heater core



· Radiator



Are any of the hoses, clamps or pipes leaking?







Visually inspect the following components:



· Block heater



· Coolant pressure cap



· Core plugs



· Cylinder head gaskets



· Engine block



· Intake manifold



· Radiator



· Thermostat housing



· Water pump



Are any of the listed components leaking?







1. Pressure test the cooling system.



2. With the cooling system pressurized,



visually inspect the above components.



Are any leaks present?







Pressure test the coolant pressure cap.



Does the coolant pressure cap hold pressure?







Inspect for the following conditions:



· A coolant smell inside of the vehicle



· Coolant in the HVAC module drain tube



· Coolant on the vehicle floor covering



near the HVAC module



Is coolant present?







Inspect the underside of the engine oil fill cap



for a gray/white milky substance.



Is there a milky substance under the oil fill



cap?







Inspect the engine oil fluid level indicator for



a gray/white milky substance.



Is there a milky substance on the engine oil



fluid level indicator?







Inspect the automatic transmission oil fluid



level indicator, if equipped, for a gray/white



milky substance.



Is there a milky substance on the automatic



transmission fluid level indicator?
