So I was driving on a 35* day in February, punched the throttle and did some full boost pulls. I was entering a freeway so was increasing speed from a standstill, and noticed the car felt really slow. A quick glance down showed 3/4 temp gauge. Instant panic ensued, it really is a horrible horrible feeling of impending doom, and i immediately assumed I was going to blow the headgasket and warp the engine and blow up the car haha.
Shifted into 6th and started cruising at 100km/hr, looking for somewhere to pull over. Temp rapidly decreased down to normal.
Hmmm what? I continued home, off boost just in case.
Sitting in traffic with AC on, temp crept back up, no more than 3/4 but still terrifying.
Temp climbed again when doing a full load pull up a very steep hill, and came back down shortly after.
The car has all oem ducting and undertrays, cooling system properly bled.
I believe there were multiple issues at play.
Firstly, overheating when stopped could have been the ebay ASI fans not adequately pulling air through, and the waterpump failing.
Secondly, overheating on pulls could have been the thermostat sticking and the waterpump failing. I had a look at the Goldcoast Mazda Dealership service records, indicating ONLY THE TIMING BELT WAS DONE AT 100km, nothing else. MORONS!
So the car sat very sadly while everything was ordered
All genuine parts
I also bought a Garage Star cooling panel to help divert air through the rad rather than over the top, although the NB is significantly more sealed than NAs so this piece was also to help clean up the look of the engine bay.
I decided a full set of gauges was necessary to properly monitor the engine, so I figured while the coolant would be drained I should install a coolant temp sensor block. I chose Works Engineering as I have been very happy with all their products previously, and this was no exception. Very well priced, quick delivery and fantastic quality. More on the gauges later
I opted for a complete Stage 2 cooling set up from FM, including their Crossflow radiator, sealed shroud and twin 2700 cfm 12” SPAL slim fans.
The radiator itself performs outstandingly, my car warms up considerably faster, however runs cooler! The oem gauge sits a notch lower than running temp previously. You have to buy the fans and the shroud also, as the neck of the rad is moved completely to the left so it would foul on the stock fan set up.
However there are many cons.
I had to go to Bunnings and buy my own bolts to mount the fan shroud.
I had to trim the shroud as it wasn't sitting flat. It also hit the coolant overflow line, had to be trimmed.
Also didn't fit my SE at all, even though it was ordered for an MSM.
I had to have the oem intercooler piping very skewed just to get the rad in.
Had to grind out the holes in the actual radiator mounting plates to reach the rad, the whole thing is under considerable tension, and doesn't sit squarely either. For the amount it cost landed, which I will not disclose as it is a hideously large sum of money, I was expecting far far better.
Quick engine bay shot after everything was installed. Even got a brand new coolant overflow bottle
Pretty pleased with myself at this point haha, car really was driving perfectly.
Installed the BuddyClub P1 wheels with RE002s and gave it a proper wash and detail.
Nice end to a very stressful month haha.
