Follow the bottom radiator hose to the block.

Remove the hose. There will be a thing with 3 bolts that the hose attaches to.

Unbolt it and you will see the thermostat. Give it a tug and remove it.

Clean up the hole it came from, install the new one.

Reseal and install the flange.

Refit hose, fill with water and bleed.

ultra blue is great stuff. i used it on my water pump (with fingers tightly crossed cos it was my first mechanical work) and my exhaust joins - all are perfect.

when you 'clean up the hole it came from' use a razor (if there's sealant still hanging there) and/or some light sand paper.

i'm doing this on the weekend, if i think to do it, i'll take photos - it looks like a bitch to get to the housing bolts.

Most R33 doesn't come with a thermostat, my blown engine and the replacement engines doesn't have one either. I bought a Nismo thermostat and it's installed on my current engine. Most of my friends and replacement engines also doesn't come with a thermostat. I don't even know what the OEM thermostat looks like. lol

RPR33, Check your radiator and hoses. If your temp gauge is going up, then radiator is your best bet. Mine recently sprung a leak and cause the temp gauge to go skyrocket. Now i'm using a Koyo OEM replacement and my car works like a charm now.

Hey guys I just wanted to know how to change my themostat on my r33 s2. the thing just isn't heating up!!!

rb30 thermostat is direct fit replacement. all cars should run one, my car sits at 76 degrees with my rb30 thermostat and the PWR radiator.

as for R33's - yes they should all come with thermostats - someone removing them for some silly reason. doesnt help the car at all to remove it.

      Just had a look, they don't. Fuelling on the base map is purely alpha-N, and the ignition table is MAP. Remember it's just a base map to get the car moving

      Hi everyone, I’m Dave from Canberra. Here's a few pics of my 1992 R32 GTST coupe which I imported back in 2006. Only mods so far are HKS Hi-power cat back exhaust, K&N filter, ATC Volanti steering wheel, Pioneer stereo, amp and sub. This was my daily driver up until 2015 and sadly hasn’t been driven at all in the last 5 years due to marriage, work, and kids taking up most of my time and spare cash.As such its in need of a bit of TLC and one of my goals for this year is to get it back to running condition and maybe look into club/historic rego. I’ve joined SAU so I can ask a few questions along the way (although I promise to google Current Problem +SAU beforehand!)

      From talking to the mx5 guys the NC doesn't actually need bonnet vents like the earlier NA and NB models, due to a better designed cooling system and undertray design There's plenty of them used as street cars and weekend track toys running anywhere from around 170 to 250kw with stock non vented bonnets, I initially was going to get some bonnet vents, but, as they are not actually required, I'll put vents on hold for a while and just monitor temps, though I do need to get something to actually monitor engine oil temps though, coolant temp can be pulled from the OBD2, but the oil gauge in the car is not actual oil temp, it is only a calculation based off coolant temp and RPM ☹️ They do recommend upgrading the radiator, which I have already done with a triple pass, and the only other thing they recommend for a street car is heat management, like I talked about above to protect bits in the engine bay from radiant heat, and to either replace the nearly 20 year old plastic coolant expansion tank, which I have done, or get a aftermarket alloy jobbie for some bling They did also say that if I wanted to track the car on occasion a oil cooler and sump baffle would be required, and as I already have had a sump baffle installed when the engine was out......... I'm going to get a oil cooler with a thermostat....... just in case I do eventually track the car, but probably not, but still maybe...🤪
