I think it was an air pocket after all. 1) I removed any hose connection I could find and tilted the car is various angles to drain the existing coolant. I recovered almost 5 gallons. 2) I replaced the thermostat and heater control valve since the coolant was out. 3) I used by HD /AirVac...

A friend today suggested that perhaps I have a small air pocket blocking the thermostat. He recommended that as i see the temperature rising I should blip the throttle to speed up the water pump eliminating any air voids present. His argument being that at idle the blade is barely turning. Any...

Good afternoon. Some updates. I had a great call with Scott Swartz yesterday that was most enlightening. Speaking with him about the heater bypass, I located a vacuum line that was off my heater control valve. Specifically I was able to find a disconnected vacuum line to the heater control...

Thanks Howard. I'm not sure of the thermostat temp - I thought it was 190 - but see below - I was able to stabilize yesterday around 210 A little update Yesterday afternoon I ran the car for 1 hour with the cap off and it stabilized around 210. Outside temperate was 80 and intake temperature...

Got some info to report. The car is one of the two rapier models that was built in 2011 by RCR, so I don't have all the info. Here is what I verified. Lets get some clear data into this thread. 1. What model number/type electric pump are you using? Meziere High Flow 55 GPM remote...

Thanks. I’ll get the answers to these questions and post shortly. Thanks again

Yes. I am running both the electric pump and engine pump Not sure on the heater valves. I might have to talk to Fran since he built the car.

Thanks to all for the suggestions. Here are some pictures that might help. #1 is header tank with connections #2 is overflow tank #3 fans installation I went with Mishimoto 11" Race Fans as they provide 1700 CFM per fan at only 12 amps. Given the size of the fans I don't have a shroud...

A month ago I had a leak in a heater core tube. That prompted me to replace all the coolant lines from the radiator back. Problem is with refiling coolant and burping the system. 1) I am using the HD Airlift Evacuator System - recommended to my by Fran 2) I can hold 25lbs vacuum and the...

Thanks, much appreciated. I will reread my manual and email Fran for a newer one.

I am getting some scrape on the left door when I close it. Manual is absent on how to adjust the hang. Wanted some advice before I go tearing the door apart :) Anyone have experience in adjusting the gull doors? Thanks -kb

**UPDATE** Coolant swap is finished. 4.5 Gallons of BeCool later, car seems to be running 10-12 degrees cooler than before. Not very scientific I admit - but initial testing shows I am running in the 180 range now where before i was almost always above 190. Thanks again for all the...

Thanks Alex and Will. Here is my rationale for changing the coolant. Its 96 with high humidity here in Atlanta recently. On the highway - car runs well about 190-195 degrees. Any stop and go and/or red lights and the temperature creeps up to 210. My pyrometer reads the temperature...

I need to replace the coolant in my superlite. I have the Airlift II system (thanks Fran) to replace the coolant, but I'm trying to figure out how to evacuate all the existing coolant. If I drain from the radiator I think I'm leaving a few gallons in (coolant lines, block). Can anyone suggest...

Yikes, and I thought my wiring had challenges :drunk:

Fran hooked me up this spring with a coolant extraction tool. Basically air pressured, plugs into reservoir and creates a vacuum to extract all the coolant. Haven't used it yet, but planning on this weekend. Will update on the progress.

Coolant mixture unknown - came in the car already. I bought 8 gallons on Be-Cool that I am going to replace it with this weekend. Thanks for all the information and advice. Very beneficial and very much appreciated.

Have had an ongoing challenge with cooling the superlite here in the south. Previous owner added a supplemental electric water pump and I discovered the fans weren't operating properly (see earlier wiring thread). Rectified the fans but I'm still concerned about rising water temperatures when...

Just finished updating the wire looms on the superlite. Basically removed (read: stripped) all the wire added by the previous owners and started over. The original wiring loom with fuse block was in good order - just a bunch of stuff added over the past couple of years that wasn't well executed...

Thanks Will for talking me off the ledge. As always - yours is a voice of reason. I have started the diagramming using my trust ohmmeter but uncovering the rats nest has been problematic. There is a lot of splices into the original harness that just doesn't seem to make sense. In some cases...
