New temp gauge up & running.

[si tate]

The temperature sits between 75/80 degree's under normal driving, motorway driving is about 85 degree's & towing, err not towed yet..

Looks good mate, nice work

[POPEYE]

Nice looking gauge, now you can see whats really happening with the temp

[greeley]

yeah smart tah si,good work bro

thread revival!

just wondering what brand the gauge is and where it came from?

also (and I'm not suggesting you've done it wrong!), is this the best place to fit the sender?

I've heard that if after the thermostat on the way to the rad, then you don't get a true reading till the stat opens. I've also heard that it should be put at the bottom of the rad near the drain plug. Where exactly is the OEM one (truck isn't with me for 2 months now so I can't go look).

I've also heard something about adding a Voltage follower across the OEM sensor, which can then send to an aftermarket quicker reacting gauge....

Sorry for the Qs, but I'm reading all sorts of conflicting stuff, and as my truck will be dealing with a Caribbean summer and some ridiculous hills shortly, and I want to get it right...

Hi Dominic, the gauge came from here:
http://rspec.co.uk/performance-gauge...perature-gauge

The stat on a 3rd gen is down the left hand side of the engine & if you put the sender on the bottom hose it will read cold all the time, where as the top hose gives you the exact temperature because the water is streight from the engine "before the stat opens".

"I THINK THATS HOW IT WORKS"

Anyway, ive never had a problem with it & TBH i only bought it for towing the caravan but now i don't tow so its kinda redundant but i guess its still nice to have as a backup gauge.

If i were you i would'nt bother if your not towing, just put a new stat in & a good flush out, use genuine toyota coolant & you should'nt have any issues.

Si, has the sender in the correct place. Understanding how a radiator works will give you a better understanding on why he put it there.
http://www.familycar.com/Classroom/CoolingSystem.htm
Putting a sender at the coolest part of the engine will not give an accurate reading. Two major engineering faults with this engine KZN, is firstly the thermostat has been placed on the outlet of the radiator(cooled water) and not as normally found on or near the cylinder head, which is the hottest place and where you will normally find a thermostat. Secondly the toyota temp sender is placed on the side of the engine block under/next to the oil filter housing, that is why you will never get an accurate reading from the stock gauge.(3ltr)

Ask elvis is the funniest thing on radio.

Nice gauge
Do you have an 82c degree stat? Mine stays just about 82c for everything unless it's a very hot summers day and I'm driving hard, then it has gone to 90c and stayed there. Ages ago, I was pushing a bit too hard up a hill on a dual cariage way and the temp moved up to 100c ish, the dash gauge also began to move though.

It's a standard Toyota stat so I'm not sure tony, hit 90 degrees once when towing up a step hill but dropped as soon as the road levelled out.

aye, there's me answers Don't worry, I'm a tech/engineering head and not a complete noob to spannering (but by no means a time served mechanic either), I'm just new to these engines. I'd been reading all sorts about this engine not having the ideal places for temp senders, and also not being easy to fully drain when flushing (apparently impossible to completely empty without loads of hassle?), so was wondering what was best.

Seems like Toyota were being rather idiotic in the above mentioned design faults.

Does anyone know the size of the top hose off hand? I'd like to order the gauge and decent sender adapter before the motor arrives, as it's currently somewhere off the N.W French coast...
