Hi All I went to the local toy dealer buy a thermostat for the 1UZ fitted to my hilux. I showed them my thermostat and asked for the same thing. They had no way of telling from the sample what they should order. They asked me what year, I thought '98 LS400, they ordered, and the wrong thing...

My cam timing turned out to be way off. Since that has been corrected the cooling is much better. I was driving around town with a bit of stop/start traffic last week in 25C weather with the fans disconnected and the temp didn't go up. Offroad I dug it into sand dune agressively, and the temp...

My mechanic showed me today that my cambelt slipped 2 teeth on the right-hand cam and 1 tooth on the left cam. Hopefully this will resolve my power loss problems and also help with the overheating issues. Now the question is, why did it happen??? And how do I prevent it from happening again???

Firstly, I don't have a factory ECU, so I won't get any error codes. Secondly, please elaborate on how to check if I'm out by a tooth:notworthy:

Something I might be overlooking, is the fact that my engine is still seriously underpowered. One of the possible problems suggested here was that I might have slipped a tooth on the cams. My friend who runs the local toy dealer's workshop, said they've also seen it. If this is the problem...

I had a look at my thermostat and the people who did the conversion cut the inside of the thermostat out. The guy that fitted the latest radiator completely removed it. I went to my local stealer to buy a new thermostat, but the one they oredered was too big, eventhough I wanted to give them the...

I'm going to temporarily hook up the Holden radiator and see what it does. It won't cost me much as I have the rad and I'll borrow some flexible pipe from a place I used to work at that does engine dyno testing.

This is Africa, not Ford Tauruses around:dunno: I do have a fan here from a 2007 E90 BMW 3 series, wonder what it's performance will be like.

A local company makes a 17" fan that puts out 2800CFM and it's only 65mm high, but still very expensive. The thing that concerns me is that my aircon condensor sits in front so there is no space for a fan from the front. The aircon also isn't connected up yet, so I'm afraid that will push it...

No, my manifolds don't have heat shields. I think I must wrap them. I'd like to keep the big BMW radiator as we had to do a lot off work and spend a lot of money to make it fit, and I thought it would work great since the smaller BMW rad was almost there. The current radiator is...

This has probably been discussed, but I've searched and haven't found the answers I'm looking for. When I got my hilux from the guys who did my 1UZ-FE conversion, the heat was fine onroad, but as soon as I went offroad it started to get hot. They then replaced the first radiator with one from...

A friend of mine tested the fuel pressure over the weekend and it was 2.5bar at idle speed and went up to 3bar when I blurped the throttle. Is this ok? It is definately running way too rich on the current mapping, last tank only gave me 1.5km/l. Will be switching back to the previous map that...

Any more ideas? I'm taking the vehicle to my mechanic on 3rd Jan, and then he'll go through everything I've already checked and everything mentioned here.

Will it cause the plugs to die completely? All the plugs were still firing when I checked it a week ago, so there aren't any completely dead plugs. Or will it cause weak spark, and will that weak spark cause the massive loss of power?

Timing belt jumped a tooth or two? This will definitely cause rough running. Possibly, how do I check this? Plugged cats, or other major restriction in the exhaust? No cats on my rig, and I've alray had the exhaust system checked. Air filter OK? Yip, it's got a cone filter, which was...
