Can a TDI cooler leak coolant from the intake?

Only gas models. TDI= oil cooled only. The EGR cooler could leak coolant and go back into the intake through the EGR. Remove the intercooler and pressure test it underwater. Only other place coolant sees intake is the EGR cooler.

When did the coolant crack in my T6?

My T6 had a hairline crack in the coolant bottle (around the drain connection) when it was about a year old. Worth a look. Have heard of a few cases of the oil cooler seal causing this. At least 4 of our new work vans are off the road with this same issue. All less than 4 weeks old. Been told its egr cooler but will have to wait and see.

Why does coolant come out of the overflow tube?

While this may seem to be a minor issue, it can lead to dire consequences. In normal circumstances, the coolant gets ousted out from the reservoir overflow tube, the moment the engine starts warming up. This leakage is visible and may result from bad reservoir cap. Go through maintenance tips for consequences of the overfilled coolant reservoir.

What happens if you lose antifreeze with no apparent leak?

Losing Antifreeze With No Apparent Leak. Whenever a vehicle loses antifreeze, also known as coolant, the usual expectation leads the owner to check for evidence of leaks at all the coolant connections and components. Obvious coolant leaks can usually be found in the form of puddles left on the pavement.

Is there a leak in my coolant system?

So far I have pressure tested the cooling system at 20 psi and found no leaks. Today I have added the dexcool friendly uv dye in hopes of the leak showing up. After letting the dye circulate for an hour or so no leaks noted. There are no stored DTC codes, no milky oil and no white smoke from the exhaust.

When to change the TBI pump in a car?

Nice thing about the Actron gauge is the hose is long enough that you can watch it while you drive. If the fuel pressure drops more than 1 psi under 8-10 seconds of full throttle the pump should be changed and dont put the stock TBI pump back in even if your engine is stock.

How does the TBI system work on a car?

TBI being a MAP sensor based system will see the leak just like opening the throttle blades and will feed the leak and then you have a high idle. Finding the leak can be tricky as it can be the intake gasket on the bottom side if you are using a Chinese junk carb intake or you weren’t real careful putting the intake on.

Why does my radiator leak with a 6.4L Powerstroke?

Unlike the 6.0L Powerstroke, a puddle of coolant underneath your truck isn’t because of a blown head gasket. 6.4L Powerstrokes are notorious for developing radiator leaks because of the poor radiator design. The crimps on the plastic ends of the radiator tend to separate, causing them to leak.

What should you do when your car is losing coolant but no leak?

Generally, there should be a leak somewhat if the vehicle is losing a high amount of antifreeze. However, a car could be losing coolant but no leak. What should you do when coolant disappearing from reservoir without leaving any trace?

Why is there no heat in a 6.4L Powerstroke?

This is the first sign of a failing 6.4L Powerstroke. As the crack grows, the injector continues to fire fuel into the cylinder, but, there is no heat in the cylinder because it cannot make a good enough seal and create the compression it requires.

What should I do if I lose coolant in my engine?

It is very important to note: If an investigation of loss of engine coolant leads to coolant found in one or multiple cylinders on the right bank, YOU MUST test the EGR cooler for leakage BEFORE attempting any engine repair. The cylinders affected with coolant will depend on which exhaust valves were open at the time of engine shutdown.

Are there any problems with the Ford Superduty 6.4L diesel engine?

Here’s a list of the most common issues found on 2008-2010 Ford Superduty trucks with the 6.4L Powerstroke Diesel engine. Now that you know the most common problems found on these trucks, it’s time to dive deep into every specific problem and how to fix them.

Where does coolant go in a Duramax Diesel?

If it can be determined the coolant loss is from the driver’s side (engine right side) of the engine, the following information should be considered. Leaks from the exhaust gas recirculation (EGR) cooler may allow coolant to pass through the exhaust system and enter the combustion chambers on the right bank cylinders.
