Customer Question
Hello I have an overheating...
Hello I have an overheating issue with an 02 exterra 3.3L. The timing belt and water pump were replaced with an aftermarket kit. Approximately 20,000 miles later the water pump starting leaking coolant steadily. The water pump was replaced with a Bosch aftermarket pump. About 400 miles later the cutomer noticed the truck getting hot while driving at about 40 miles per hour and seems to overheat faster with the A/C on. a pressure test revealed that a heater hose was leaking. I replaced it and repressure tested the system after vacuum filling the system with 50/50 ethylene glycol coolant. The system is holding pressure at 1 bar and there are no other external leaks. I have done a block test and a cylinder leakage test and both passed ok. I checked and adjusted the ignition timing to 9 degrees btdc. The truck has a torque convertor clutch circuit intermittent code and the short term fuel trim for bank 1 and bank 2 are in the negative values ( around -10 each ). all of the spark plugs insu

All of the spark plug insulators are white and the ground electrodes have light tan combustion deposits. The piston heads are dry and have mild carbon deposits on them. The short term bank 1 and 2 fuel trims are around -10 at idle and at 2000 rpm.

Hello and welcome to Justanswer!

Incorrect cam timing can cause fuel adaptives to go high positive or negative. Has cam timing been rechecked since the issue started?

Does it have any driveability issues?

No drivability issues. When I replaced the water pump I verified cam and crank alignment.

THE ENGINE GRADUALLY starts to overheat after about 20 minutes of driving.
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 2 years ago

Does temperature come back down if you stop?

Does the cooling fan work?

Customer reply replied 2 years ago
No it dosent come back down. The fan clutch was replaced about a year ago the radiator was replaced about 3 years ago and the thermostat was replaced about 20,000 miles ago.
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 2 years ago

How hot does it get? If you continue to to drive will it bury the gauge and boil, or does it just run hotter than it should?

With the radiator cap off and the engine running during bleeding it boiled over but I haven't allowed it otherwise to get real hot because of the possibility of warping a head.
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 2 years ago

When it came back initially was the coolant still at the level you left it?

I checked it after it cooled down some what and the radiator was full.
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 2 years ago

If it overheated quickly then I'd suspect the water pump or a stuck closed thermostat but your symptoms point to a restricted radiator. When the cores become restricted it effectively reduces the capacity of the radiator which will cause the engine to run hotter under load. If there are no internal or external leaks, it takes that amount of time for it to get hot and it's worse with the a/c on that points to the radiator.

You think it might be restricted with corrosion deposits?
Nissan Mechanic: sprinkles08, ASE Certified Technician replied 2 years ago

Yes, it could be corrosion, something left in the radiator during manufacturing that has accumulated, I've even seen casting sand break free out of an engine block and end up in the radiator.
