No mate. Not really an issue. You may find your oil is sludgy, under the rocker cover, when you pull it down, as the oil is designed to run at high temp. Change your oil and filter when you get a spare $50.
You computer will try to compensate, as Dean said, by thinking the engine is cold, and adding more fuel to richen it up. Temp gauge should be a third to half way up when fully warmed up.
If you run without a thermostat, you may actually 'overheat' your engine. (coolant travels too quickly through the radiator, and doesn't have time to cool down, basically)
Yeah solid I’ll get into this now and also check the thermostat after iv got another ready to replace it with. Iv been researching all day and the only information I can find on damage from stuck open or missing thermostat is fuel consumption. I think maybe the previous owner had it stuck shut and car was overheating so they just removed it? I’ll only know when I pull it I suppose
I think Deaner's onto it... I'll add that my EF used to get in the 9s on a trip, 10.5s around town. Manual though.
My current EL wags (auto) gets around 14.5 to the hundred, but there's something not right with it. Done TPS, oxy, MAP, still tries to stall occasionally at the lights then catches itself again. I'm actually thinking now it might be fuel pressure reg sticking intermittently but haven't bothered going any further with it. My 302 XE gets not much worse than that, doing identical driving.
With yours, no trip computer means you'll have to calculate it the old way. Take fuel used, divide by km on the odometer and multiply that number by 100 to get litres per 100km.
Sorry to keep bothering you deankdx but if my thermostat is actually stuck open what problems can this cause? Apart from fuel economy? I will definitely replace but probably can’t do it straight away. Obviously it’s not as bad underheating my car than overheating but can I cause more damage with a stuck open thermostat?
Found a few thermostats on eBay and they pretty cheap, I might just change it anyway. At least if I do that I know it’s sweet and not stuck open as I’m more worried about that now than fuel consumption 😂 but if it helps with fuel that’s a bonus. But yeah the Ute never gets hot at all and I’m actually thinking you must be right about it being stuck open
i used to get 10% better economy from 91 to 98, i don't think 95 was popular back when i had it.
i don't like 91(i'd use it in a stock newer car happily), and going from 95 to 98 i would expect not much difference if any even cost..
the XG should be fine on 91.. i'm sure it would cost less over all.. but my question is whether it would make the head gasket pop sooner?
hard to compare fuel economy without a figure.
Iv been reading up and I think you’ve got it... the thermostat must be stuck open as the car never gets hot. It literally never even makes it very much passed the start line of the “normal” part of the temp gauge. If it has a thermostat? I’m just trying to find it now. If it does and it’s stuck open is that a WD-40 kind of thing or should I replace it? First I need to find it I guess 😂
I’m not actually positive what it’s getting in kms to litre I’ll have to monitor it and let you know. I run it on 95 octane as I was told by my mate that’s the best for those motors. Would you reckon I should swap to 98? Will that make a difference? He says that the older cars are fine on 95 but iv always been under the impression 98 is the best for everything.
