Pinching radiator hose reliability for H gaskets

Loosing coolant and can pinch hose easily and now have scheduled a pressure test at dealer. Trying to be prepared for what dealer may say. Can pinch the hose completely in the morning before starting. Can not find any leaks or see coolant on ground. Losing about a pint every few days. Also, not much coolant going into non pressurized side (fender side) of plastic tank. I know the EGR can also be leaking but would be going out the tail pipe (?). Not noticing bubbles with radiator cap off and engine running. Thanks,

Lots of leaks are very hard to find but relatively cheap to fix. Don't start worrying until you have their diagnosis and repair estimate.

Where do you find the EGR blocker plates?

I believe there is nothing in the EGR valve itself that has coolant in it. What leaks is actually the EGR cooler. The block off plate prevents the exhaust gas from being sent back into the intake.

Well, dealer says the heater core is leaking and will cost $13XX to fix. Should be ready tomorrow afternoon. Said they have to remove the dash to get to it. I wonder if the "diesel smell" in the cab was really coolant smell?? Different dealer than one that replaced the gasket on the "down pipe".

Seems likely that might have been what you were smelling, given that it's been loosing coolant.

However, to my nose they don't smell the same.


Hope that fixes it for you.
