Just wanted to give a quick shoutout to @Extinct for the awesome Inline Thermostat mod.

I started reading and soaking up a lot of Rover V8 related content recently. The more I read, watched, and absorbed the more it became obvious that these motor were designed in a time when engines ran cooler and high octane fuel was available at the pump. The folks in the UK building these for racing applications run them below 170 degrees F for maximum performance. Because of the collective knowledge of the internet (or lack-thereof in some cases), I decided that my OEM 180 T stat wasn't keeping my motor as cool as I'd like it to be, so I bought Extinct's kit. Since my truck is new to me and has a new radiator, hoses, and water pump I am not familiar with the cooling system. Even so, the entire inline stat installation only took me a few hours, moving very slowly at every step.

The engine temps are now more along the lines of what I believe these engines were designed for. The bulky OE stat is gone so the system is simpler and takes up less space in the engine bay. The motor comes up to temp in the same time as it did with the OEM T stat. Overall super happy with the modification. If you are on the fence about making it, I'd recommend it 100%. It's affordable and simple.

 

Best mod you can do by far. I would never run a standard LR design thermostat, regardless of manufacturer. In fact, I have a few extra from the ones I have removed if anyone would like one (you pay shipping). PM me your address and I will send you your choice.

 

😂😂😂

 

Link for @Extinct kit?

 

PM me your email address and I will send out information.

 

Yes. I feel guilty not sending out one of these earlier thanking Extinct. Many emails exchanged before, during, after inline mod trying to figure out high running temps. Figuring out bad one year old radiator needs replacement and addition of oil cooler. As well as many other questions answered. Thanks for all of the time and help Extinct.

 

Interesting. After I went inline I was getting high temps only is super hot temps with high grades. I sort of gave up after I added some water wetter and removed the grill and was able to keep the temps around 210 at the very hottest days straight up a mountain.

How did you diagnose your bad new radiator?

Can I add an oil cooler to my 04?

 

Yes, oil cooler will probably knock off 10 degrees in your extreme conditions. 04Disco2VA was in FL - temps similar to yours but flat ground. He eventually ran a test with no thermostat installed in housing, still ran hot. Don't remember if you tried that? My general read on yours was you were really taxing the cooling system beyond normal operating conditions for the rest of the US. You are gonna be my beta tester for the ginormous radiator mod next summer.

 

Thanks Extinct!

I never tried empty housing because I was able to manage temps by removing the grill. I figured on the 2 or 3 times a year I am driving up a mountain in 105 degree heat, I will pop the grill off and hope for the best.

We are going into ski season now so my motivation to troubleshoot overheating issues has vanished.

I am down to help test anything!

 

Yeah, hit me up in April.
