Thanks, I've run it for about 10 minutes at a time, just idling and light revs once a bit warm. I've been too scared to let it run longer for fear of causing damage. What is worrying me id that the heat isn't getting to the heater radiator either - shouldn't that be getting hot straight away...

Hi all, Does anyone on here know the diameter of the crank pulley on a stock 1UZ ? (the pulley for the accessories belt - not the cambelt pulley) I'd be really grateful to know. I haven't got an easy way of measuring it, as my calipers are too small. Other than a rough and ready string round...

Hi all, Thanks for the replies. Sorry forgot to finish the sentence.... I meant take the thermostat out to test it - wasn't planning on leaving it out. but I've been running it with the heater valve open and the heater fan on, and that is not getting hot. I've got a Gates cambelt kit with a...

Hi, No I ran it last night, for about 5 minutes, no heat at heater radiator or main radiator, gauge went up to 80 degrees C (nb the gauge is uncalibrated) engine felt warm on the plenum and the cam covers. It just occurred to me - my car is on ramps at the front - ie pointing upwards at the...

Actually scratch that - just looked in the garage and I put two whole 5 litre bottles in, so at least 10 litres went in. Mat.

Hi all, Finally got my build running, 1UZ into a 1979 Lotus eclat. After a very long time of fabricating, designing, building, electrical systems, and making a full custom wiring loom it started first click like a new engine. BUT - I'm having trouble with the cooling. The engine starts and...

Hi, yes I got a set of 8 iridium plugs, haven't fitted them yet. I finally got my build finished and it started first click like a new car. It's been about 7 years since the engine came out of the soarer it was in!!! I have oil in it and turned it over on the starter every couple of months, got...

Hi, thanks for the replies and the part numbers. Mat

Hi all, Does anyone have a recommendation for plugs for a 1uz from a soarer, unmodified, I think I'd prefer platinum for the longer life, but open to any suggestions from those in the know. Thanks, Mat.

Hi all, Sorry for posting it in the general section - mods please feel free to move it if it shouldn't be here, but does anyone have the wheel that the cable sits in, I have been drilling mine out to fit the larger nipple on the cable I have on my car, but it snapped when I tried to drill it...

Hi, I stopped looking for the double pulley, as I've gone for a Rotrex C38 which can run off a 6 rib belt (although they recommend 8 rib belt) and found an OEM double sided aux belt, using the location vacated by the idler pulley which used to be the hydraulic fan pulley. It has more than...

Thanks George, So I guess I shouldn't worry about not having the time circuit on the cold start injector? Cheers, Mat.

Hi all, Sorry to bombard the forum with wiring questions - but I've been going through my loom, figuring out what does what, against the lextreme diagram I've got, and the toyota diagram that I found somewhere. My 1uz has the cold start injector, it is a 1992 soarer engine, with 40/40/40 plugs...

Hi all, I'm wiring a 1uz, I've got the loom off the car and going through it with the diagram it all checks out. However there are a few connections that are not on any diagrams I've seen - the engine is off a 1992 soarer, the 40/40/40 plug type of ECU. There are about 5 wires I can't locate...

Thanks Rod - good point! I'm guessing it's "normally closed" so closes to ground with the engine off, then opens under normal oil pressure? Thanks, Mat.

I found the above pic on the web - my oil filter barcket off was like the one on the left (now have a remote filter) but the sender/switch is seen on the black one on the right. This is the sort I have. Is that actually a switch? If it is I will junk it unless it is needed to send an input to...

Thanks - sorry I just presumed it was a pressure sensor - I have a photo but it wouldn't let me attach it and I don't have a way to crop or compress the photo It's a 1992 soarer engine - has (had) the angled oil filter bracket and the sensor/switch is mounted onto the bracket on the other sde...

Hi all, I want to wire the oil pressure gauge on my 1uz. I've got the stock pressure sender, but a VDO oil pressure gauge I'd like to use (or I will use any other if there is a known one that will work accurately). How do I work out what gauge to get? Do they have a standard for volts vs psi...

Hi all, I'm building up my intake, and have got a silicone hose to go from the MAF body to the throttle body inlet. I had planned to fit a sealed 16mm take off to connect to the idle speed control. But looking at the MAF body, there is a shaped section on the side, low down on the side facing...
