So let's continue, I've waited for everything necessary and prepared for assembly, now I'm starting to put things in their place.

Here are the rest of the consumables, I replaced everything that caused doubt, all hardened hoses, gaskets, etc. Also cleaned and slightly polished the intake pipes of the compressor part of the turbos and also installed a Toyo oil cooler with an adapter for an HKS oil filter and reinforced hoses with fittings. Adapter with thermostat!

Essentially here's how the new water pump differs from the old one, it's much lighter as well). I got the water pump from a 1JZ-GTE VVTI engine. The new water pump doesn't have the radiator fan hydraulic actuator pump, which is why its construction is simpler and lighter, plus there’s a more advanced impeller - metallic instead of plastic with better blades for improved cooling)

Spent a lot of time looking for a good sports thermostat with earlier opening, but couldn't find anything decent. So I'll deal with this issue closer to spring, but when disassembling the old water pump, I found an advanced 72-degree thermostat, whose origin is unclear since it has no markings, but stock thermostats are usually 80 or 82 degrees! I think this one will be sufficient for me and there's no need to replace it anymore)) What doesn't happen - happens for the better)

Well basically transferred all tubes from the old water pump to the new one and installed it in its rightful place). Everything fit perfectly, even though my engine is 2JZ but the water pump is from a 1JZ — Toyota forever!

Prepared the upper water pump hose for installation. Unscrewed the stock coolant temperature sensor and screwed in a new Bosch sensor specifically adapted to the Autonic SM4 engine control unit.

Next, installed the hose on the motor and proceeded to install the timing belt system. Matched the marks, put on the belt, pulley, and tensioner. Turned the crankshaft by 360 degrees, checked for mark alignment, and then pulled out the pin from the tensioner)

Now we install the timing belt covers and the pulley-tensioner of the accessory drive system.

Bolt the water pump pulley and put on a new shorter belt)

We've finished with the front part, now moving to installing the hoses.

Well that's all I've managed so far. To see the work done, look at the intake manifold which I haven't touched yet, and at the polished pipes which were previously like the manifold))

More coming soon in following episodes: replacement of cam cover gaskets, removal, cleaning and polishing of the intake manifold, removal of an additional throttle valve, rear crankshaft seal replacement and final assembly for engine swap)

Thanks for your attention, see you next time. I'll be glad to read your comments and likes)
