Hey everyone, I have an interesting issue and I'm curious if anyone has experienced something similar. Recently, while driving uphill, I noticed coolant leaking from somewhere in my vehicle. It sprayed out over my right shin from behind the throttle area panels. Strangely, the leak stopped once I reached the top of the hill. After inspecting my vehicle, I couldn't pinpoint where the leak was coming from. The same issue occurred during another uphill drive, but there was no leak while going downhill or driving on flat surfaces. Has anyone encountered this issue or have any insights on what might be causing it? Thank you, Paul.
One common issue associated with them is a tendency for head gaskets to fail.
Do you know which engine is powering your vehicle - is it a Cummins or Detroit 4-53? When climbing uphill, what does the temperature gauge indicate? It seems like the radiator may be overheating and pushing fluid through the cap relief tube. This could be caused by the fan pulling air in instead of pushing it out. If the engine is running smoothly, it is unlikely to be a head gasket issue.
User old-iron-habit inquired about the engine in the vehicle, specifically questioning whether it is a Cummins or Detroit 4-53. They also raised concerns about the temperature gauge readings when driving uphill, suspecting a radiator issue. It was mentioned that the vehicle is equipped with a 4-53 Detroit engine. The temperature gauge has been replaced with an aftermarket one that reads in Celsius, reaching the high 90's 'C uphill and dropping to the high 80's 'C downhill or on flat terrain. Suggestions were made to replace the old radiator cap and inquire about the appropriate pressure rating for a new cap. It was noted that the fan is blowing air, not pulling air, and the efficiency of this setup was questioned. Despite these issues, the vehicle is reported to be running smoothly and powerful.
Answer: - The issue of coolant leaking specifically while driving uphill could be related to the increased pressure on certain components of the cooling system during uphill driving. This pressure might be causing a weak spot or a faulty part to leak coolant. It's recommended to have a professional mechanic inspect the vehicle to identify the exact source of the leak.
Answer: - It is not normal for coolant leaks to stop spontaneously once the vehicle reaches the top of the hill. This behavior could indicate that the leak is somehow affected by the angle or pressure changes experienced during uphill driving. It's important to address this issue promptly to prevent any potential damage to the vehicle's cooling system.
Answer: - If you are unable to visually identify the source of the coolant leak, it's advisable to have a professional mechanic perform a thorough inspection. Mechanics have the expertise and tools to diagnose leaks that may be hidden or difficult to spot. Additionally, they can pressurize the cooling system to replicate driving conditions and pinpoint the exact location of the leak.
