Thread: High engine temp V8

The standard one

I've been waiting to get my bluetooth dongle working,, and now that it does--
one ten minute drive and



97 while moving and over 100 when stopped.(ambient was around 25 and raining!)



this is with new everything. rad, pump, hoses,

so this is what LR designed the V8 to run at.



I'll start with some water wetter, but can see a new thermostat in my future---

Went for a quick run out to Oakey and back to set some sort of benchmark,,
around 93 with clean air at 100kph,
following a petrol tanker at the same speed with a two to three second gap added 5deg instantly.
a two minute idle in the driveway saw 101.

Mine with block flush and all new cooling system...ALL..is av of 88 tooling along and up to 94 in traffic on the scangauge. Standard thermostat.

Pedro's, very similar to what I'm getting using my OBDII wifi scanner. 93-97c when driving. At idle in traffic in Drive A/C on it occasionally tops 100c but quickly drops when I accelerate away. Today I wanted to test it towing for the first time with a 2.2t caravan. Up a long climb on the freeway foot to the floor speed topped at 65km and the temp dropped to 91c. The harder I drove it the more cooling was applied. After a lot of chatting to various LR specialists, this is exactly what these engines run at . They have all told me the best investment I made was fitting the engine saver low coolant warning. Cheers Craig

Pedro, You may want to try the lower temp thermostat, cant hurt and could save a lot of money, having said that it is within agreeable limits.

It could have air in the system. My v8 from factory never had temps that high even towing 2 tonn up the hills of Paddington in a 38 degree summer day. It only started those temps when I had cooling system failures and later when I had a head gasket gowing and overpressurising and overheating the water jacket.
Cheers

A lower temp thermo may not work per one of the posters above but also may just mask a problem that when it does get worse will do do quickly and spectacularly.
