Would the water pump show any visible signs of a failure? Do they suck in air through the weep hole?

I have a 2006 ud with the jo8e. I’ve been losing coolant. Not a lot, but usually just enough to trigger the low coolant alarm. Sometimes 16 ounces will top if off. The alarm sometimes is on when the engine is cold but after driving a few miles and the coolant starts circulating it goes...

New discovery... I was putting the fuel treatment in and saw improvement, but later realized that it wasn’t necessarily the fuel treatment, but it was the full tank of fuel. When the tank got below 1/4 the knock would return, but after a fill up it went away. Is there a pickup tube that...

I have a 2006 UD 2000 with the hino engine. 218k miles. Lately I’ve been noticing a slight knock at certain rpms (usually around 1200). Could this be injector knock? I don’t have any check engine lights. I ran some Lucas fuel treatment in the last tank and it seemed better but the next tank...

I got my new turbo installed today. Everything went well. No broken bolts! My check engine light is out and the truck runs great. Thanks to everyone for the help.

My vnt controller/actuator is bad. I believe the turbo itself is ok. I was unaware of the need to maintain the linkage on the turbo and I’m pretty sure the guy I bought the truck from never knew either. Sean at tri-state turbos was very knowledgeable and helpful.

I called my local hino dealer this morning. They weren’t able to cross reference any of the part numbers from the turbo. He told me that he needed a hino vin to look anything up and since my truck was a UD he referred me back to the nearest UD dealer. I found a good deal on a new...

Thanks to everyone for the help thus far. I have not ordered any diagnostic tools yet, but instead I decided to investigate a common issue I have read about from many previous posts on here. The turbo and vnt controller. I pulled off the back cover on the controller and indeed it is fried...

Thanks. I’ll keep searching.

Yeah, that’s true. It may come to that if I don’t figure it out soon. I’m sure I’ve made a more than a few people quite upset following me while going up a hill.

I called them. They initially said they could scan it, but the guy on the phone asked someone else since it was a ud. Then he said no. Apparently even though it’s a hino engine, it uses the Nissan ud ecm.

The closest UD dealer is over 100 miles away. I could limp it there, but it will only go 40-50 mph. My reason for trying to find a scan tool to purchase is more for future needs (and this time). I’m just thinking of a future scenario when it may or may not be able to limp there.

I have a 2006 Nissan ud 2000 with the hino jo8e 7.7, 165,000 Miles. I initially had a random check engine light, but turning off key and restart would correct it, but now it’s on continuously and the truck will not rev past 1900 rpm. All local repair shops encouge me to take it to the dealer...
