I will be replacing the coolant in my AE93 Corolla with the redtop 4age motor. Going to replace the thermostat as well. Just wondering, what temp rating thermostat do I need, and is there a specific part number for it, or are all thermostats the same size, with only the temp they open up being the difference between them?

Not sure if it is faulty. As the coolant is rust colour, I'm thinking it may be a good idea to replace the thermostat as well. Car has never overheated, gets up to slightly under 1/2 way on the temp gauge at most. But it can take a while to get up to operating temp on colder days. Car does run a bit rich also.

replace the thermostat with a genuine part, while the coolant's drained take the radiator to a radiator place to have the core unblocked. They remove one of the tanks and clear the core tubes with a steel rod. If it's never been serviced before it will be at least 40% blocked.

      MWR Oil Pump

      Thanks for your response, I’m just hoping and praying that the oil pump will withstand the over-revving which is why I purchased the product. Also, I know very well about the flaws of the 2ZZ in regards to the oil pump and oil sump.

      MWR Oil Pump

      MWR are a reasonably respected name in the aftermarket 2ZZ business, they're not the cheapest (especially with shipping) but the products are usually solid. In this case though it is only the oil pump gear itself which is upgraded (as that was the issue with the stock ones), the housing is new/refurbed OEM Toyota/Aisin. FYI 4340 is the grade used, it's a high-tensile chrome-moly steel. I believe the stock ones are sintered (ie powdered steel pressed in to shape at high pressure/temperature), which contributes to their propensity to shattering (although I think it is much rarer than people are lead to believe, and usually as a result of over-revving via mis-shifting)

      Engine starts but won’t rev, only idles. 2002 Hilux 4d4

      I left my fridge on in car for five days and it completely ran the battery flat. I have replaced with new battery and engine starts but only idols cannot be revved at all. Any ideas?

      MWR Oil Pump

      My new Monkeywrench Racing Oil pump came in the mail last week ago, which had been shipped from RideRound.nl in the Netherlands. Does anyone know anything about Monkeywrench Racing? Do you all think I made a good choice buying this aftermarket oil pump? I ordered it to to upgrade from the stock OEM one which is vulnerable to disintegration. The aftermarket one is meant to be bulletproof because it is made from some type of so-called '4340 steel'.

      Loss of power

      Hi Darryl, I’ve just read your post about loss of power in your UZJ200R and multiple fuel pump replacements. I have the same issue in my 4.7L and was wondering if you were able to get the issue resolved? My loss of power occurs after approximately 5 hours of towing a load (caravan) and results in loss of power and eventual engine backfiring. The problem resolves it self after a few hours of cool down time. I have replaced the fuel pump, fuel & air filters, plugs, ignition coils and mass airflow sensor but still have the issue. My auto electrician suggests that I now replace the fuel pump control computer (part no. 89570-60160) that sits on top of the right chassis rail just forward of the right rear wheel. He thinks this might be getting hot which could then affect the integrity of the signals being sent to the fuel pump. I look forward to your reply.
