overheating

Good day, I've been recently experiencing the dreaded temperature rise when going up long hills, or driving in deep sand... What do you think about my viscous hub fan?: It feels firm when the car is cold. Can barely turn on its own. When the car warms up and just after I turn it off, it keeps...

Hi All, I hope everyone is enjoying some extra time working on their projects. My 2003 ZD30 Di overheated last week and after about a week of trying to bleed the system I couldn’t get it to blow warm air consistently through the air vents then it would overheat again. After trying and trying I...

I know this has been bought up a million times but I cant find a "simple" answer. After a high country trip on the weekend I worked the car pretty hard (n/a td42 silvertop) it was hanging around the hot mark up hills but never went past it. It had blown alot out of the reservoir though. It...

Hello out there fellow Patrol'ers, I am sure this has been discussed to death, but I am struggling to find some definitive answers on the forum. What I have is one of the many GU Patrols with marginal cooling capacity. I am finding that it often ends up getting up to over 115 degrees (measured...

Hi All, I have a 1997 GQ Patrol with the RD28T engine, she is running very hot at the moment. When I bought the car about 3 years ago she was running a copper radiator out of a 4.2. Last year a belt snapped and got caught in the fan and went into the radiator so I replaced it with an alloy...

Hey everyone, new to this forum and I could find anything in the search bar. I've got a 1989 TB42 Auto, it's been acting all funny and the transmission is starting to cook itself, under normal driving my A/T oil temp light comes on and it smells like burning tranny fluid, I serviced the auto...

G’day Guys, 2009 Nissan Patrol ST I think I am in the process of solving this problem, but, I thought I’d make this post anyway as there don’t seem too many posts about it. My Mrs. Gave me a ring yesterday morning 10km from home saying the car overheated and there was a milky liquid coming...

Hi All! First post, I have done a lot of research around this but haven't found much.. Im having some overheating issues with my Patrol Ute, going up a hill in 3rd foot slowly making it the temp gauge creeps up to 3 quarters, once at the top of the hill if I back off the temp gauge goes...

Zd30- When mechanic replaced tran fluid he noticed the fan shroud was against the radiator core and was rubbing through. Rad and rad hoses replaced. New fluid, I don't know what brand. Went where I have been before and the temp rose to 105 before I pulled over and let it idle down. Spoke to...

Hi guys, I have a gu 4.2l with a after market front mount intercooler and the boost wound up to 15psi and I usually have my 240blitz spotties on the bull bar but I am having trouble with it overheating when I tow I was wondering if others have had the same and how did they fix it? I am leaning...

hi all, been having a lot of overheating issues at high revs and low speed, especially pushing it up hill (in the bush, up hill in 2nd or 3rd is worst). a mate reckons maybe the thermo fan at the front of the radiator isn't engaging. how do i test it, and when should it be engaging and kicking...

Hi guys, Having an ongoing issue with my TB42 that I wanted to get some feedback on. When pushing it uphill, especially if the weather is a bit hot and I have the air-con going, the car heats up quite a bit (around 3/4 of the temp gauge). As soon as I am back on a flat stretch, it cools back...

Have tried to find any other members with this problem. Around town driving at low rpm temp raises right up to mark before hot, also if idling for extended time eg Drive through Kfc Macca's etc. When on the open road it will drop back half way or less on thirty degree day. I have replaced the...

Hi, I am hoping someone can help me out. I have a 99 GU 2.8 turbo diesel with 258xxx kms on it. I recently had a radiator pressure test and found out the welch plugs needed replacing. Got the welch plugs and the manifold gasket replaced thinking it would solve my overheating issue. Today I took...
