Radiator problems of the 2002 Dodge Ram 1500

I have a 2002 with the 4. 7l that I am having overheating issues that I have never experienced before. When driving around town or even on the highway under 65 my thermostat never goes above just under halfway. Driving in town I have yet to see it go above that point. However, when driving down the highway if I increase my cruising speed to 70, my thermostat climbs. When going 70-75 it will go up to about the 1 o'clock point before I slow down, so I don't know how far it would go if I continued. I replaced the thermostat, flushed the radiator, replaced the fan clutch . But the problem remains.

Tl-the contact owns a 2002 Dodge Ram 1500. The contact stated that while driving 55 mph, the low coolant warning light illuminated and white smoke started to emit from the exhaust. The contact mentioned that he waited for vehicle to cool down and added coolant fluid to the radiator. The vehicle was not taken to repair shop or dealer to be inspected or repaired. The manufacturer was made aware of failure who filed a report and did not offer any additional assistance. The failure and current mileage was 54,000. Pmb.

Thin cracks appeared on upper right of the main radiator, fluid leaking out. Car had not sustained any accident and is a clean title. My conclusion is that inferior products/polymers were used to manufacture this radiator. This is not an aftermarket radiator, but the one that came with the vehicle from the manufacturer.

My 2002 ram van 1500 6 cyl engine failed state required smog check. The check engine light went on prior to this. The smog report showed 3 cylinders out of 6 were misfiring. The diagnosis was damaged valves and lost compression. After the mechanic opened the engine he found both heads to be cracked. He also found problems with the water pump and radiator. The total cost of repair was $3100. After further investigation I found out that there are thousands of 1500 engines that failed for the same reason. As with the other owners I changed my oil at regular intervals and maintained the vehicle properly. I had a 1997 1500 in which the same thing happened. Dodge denies responsibility and blames the sludge build up on poor maintenance. Since it was no longer under warranty I was forced to repair it. There should be a national recall of this vehicle's engine and I should get reimbursed by Dodge for the repairs. I unfortunately didn't have a choice but to repair the engine but fear that the design defect will result in subsequent failure of the same nature. Dodge should be held responsible for this. Please help.

The contact owns a 2002 Dodge Ram 1500. The contact stated that the driver of the vehicle alerted her that the radiator hose blew. The contact did not know the details in regards to the failure. The vehicle was taken to an independent repair shop where it was repaired. The contact also stated that the vehicle would burn coolant at an excessive rate and the engine would intermittently stall. The manufacturer was made aware of the failure, but offered no assistance. The failure mileage was unavailable. The VIN was unavailable.

Upper radiator hose blew-out,@42,000 miles , after replacing increase in engine temp. Replaced thermostat and radiator, temp remained elevated. Vehicle never overheated. Engine valves started tapping, antifreeze accumulation on the inside of engine oil cap. Bad headgaskets. Engine oil & filter changed every 2500 miles. Now with the warm weather, only occasional engine tapping and no antifreeze on the inside of engine oil cap. Head gaskets must be leaking or shrinkage of the gaskets with the cold weather. Contacted Dodge and they say that they have never heard of this! checked online and found multiple Dodge vehicle owners with the 4. 7 litre engine have experienced similar problems. Poor engine design, thin walled engine block, lubrication holes in rocker arms not drilled in correct location= check replacement rocker arms as opposed to original equipment. This is a 2002 Dodge Ram 1500 pickup 4. 7 eng 43,000 miles. Chrysler should have a engine recall and replaced these defective engines as they were only available for a few years and then discontinued, I wounder why!!.
