FYI, that gauge cluster temp gauge is almost useless, just a guide. It takes forever to read properly. You want read it from the k series coolant sensor into the block. My ktuner ecu reads 180f when my gauge cluster gauge will still read c and then a few minutes later, it reads to normal temp. You could be overheating and not know it.
I highly suggest you pick up a mishimotor radiator and a slim fan. You spent so much the s​wap, no pt on cheaping out on the coolant system.
I really need kpro or ktuner as i really have no idea what temps I am at.
I am using a stock b series fan switch. I believe it says the fan should kick on between 194-203. I just can't imagine that I haven't gone over that by now lol.
Yesterday I removed the thermostat completely and the car seemed to warm up real quick. I bled the system (hell, that's all I seem to be doing) and once again the fan never kicked on. I jumped the plug so my fan would stay on all the time and the temp gauge dropped a tick below the C. remove the jumper and it climbs back up to normal and the fan never kicks on.
Now for my worst nightmare. I believe it has a head gasket issue. With the thermostat removed and from what I would think that all the major air pockets have been bled out, I had frequent small bubbles. Especially when I revved it up.
Today I tried again, but this time I had a IR heat gun. Temps seemed good for the first 30 minutes or so, but then the radiator reached boiling point. I checked the temp of the fan switch fitting and it was right around 190, but the radiator was at 209 on the outside and boiling. The water was almost at the top of the funnel. And a good amount was pushed out when i shut the car off. The air bubbles were worse today too. A lot of small and big bubbles when I revved it. The fan never kicked on either btw.
I am just so confused as to why my fan doesn't kick on, yet it does when I place it in a pan of HOT water.
Also, when I bought this swap the guy told me his buddy did the head gasket on it. And seeing as the cam timing was off, I wouldn't doubt he botched the gasket install too. My fault for not tearing it down like i told myself to do.
Maybe tomorrow I will get a video of the air bubbles coming out. I am pretty positive it is air getting in from somewhere and not air pockets in the motor. Too many for too long.
Any thoughts, please post them.
