As the title says. I take out the Viper today and I'm getting on it pretty good, as always 
, when my temp gauge suddenly pegs at redline and the coolant/water temp light comes on. I thinking **** and I smell coolant. I let off on the throttle, RPM's come down and so does the temp. Odd. Get it on it again, temps go up and I smell coolant. I pulled over and the temp dropped down to 200. Fortunately, this was only a couple miles from home. I baby it home, temps stay around 220 or so, never hit redline so long as I stay under 3K rpm.
I get home and find coolant all over my passenger side side sill and on top of the expansion tank. Looks like coolant was coming up through the radiator cap. I check over the overflow bottle and it's empty but there's coolant in the fascia. Looks like it threw up in there too. Cap was on tight, no leaks. The expansion tank was also empty.
I cleaned everything up, fill up both tanks, put in a new radiator cap, burped the cooling system and take it for spin. For the first several miles, all is well but the temps start to climb as I get on it again. Sure enough, temp gauge pegs at redline, I let off on the throttle and the temp climbs down a bit but still high. I smell coolant as well. I get home to check everything. The radiator cap is not leaking but the front fascia where the overflow bottle resides is leaking. Looks like it threw up in there again.
I removed the fascia and there are no signs of leaks with the coolant bottle or hoses to/from. Cap seems tight but it looks like it's burping through the side passage built into the plastic bottle. My guess it must be overflowing as the cooling system is pushing out air? This time, there was a little bit of coolant left in the bottle but below minimum. The expansion tank was half-full. However, my temp gauge was close to reline no matter what the RPM was.
I don't know why this started acting up today. No changes have been to the coolant system components. I did several pulls on the dyno Tues and had no issues with temps or coolant leaks. I was planning on replacing the radiator cap as it looked suspect and luckily Tator mailed me a new one last week.
I'll probably drain/refill the coolant tomorrow. Give the amount of coolant I lost today, there must be some air still trapped in the system. I'm wondering if I have one those suspect water pumps. The temp gauge/RPM behavior seems to fit what Tator told me of the faulty impeller symptoms would be.
