Since this is about as low tech as it gets, I am putting it here. Absolute, if you think it needs moved, feel free.

I have had the abosulte hardest time trying to get my engine temps up high enough that I feel safe. The combo of the Mexiere EWP and the LG supercool radiator w/ a 180* stat I CAN NOT get my engine temps above 140*. Even on the dyno with NO fan running it never went above 140. If it did right after a pull it would drop like a hot rock right back to 140*.

I saw an older post by Lou on LS1tech saying that some of us would have to "tape" the radiator to get out engine temps up to a normal operating area. What did he mean by "tape". Did he mean litterally tape over part of the radiator? And if this is right, what would I use? Duct tape, 200mph tape? And if I do use tape wouldnt the heat off the radiator melt the stick'um off the tape? i was going to use a pice of cardboard to block about 1/4- 1/2 the radiator and thought of using tape to hold it on but was worried about melting the tape.

Can anyone help me out with this?

Well here is what I think might be hurting me. The Meziere is flowing a constant amount of collant no matter what (roughly comparible to 4500 rpm). As per Mezeire instructions I drilled 2 holes on either side of the thermostat to facilitate a little coolant flow. Could the amount of coolant that is slipping through the 3/16 hole be what is hurting me? My temp sender for the mechanical autometer procomp gauge is mounted on the rear most hole on the passenger head. I can see how this would show a small difference in the gauge reading and the thermostat opening. The guage used to show me about 160-170 before it would drop (I figured that meant the therm. was opening). and since the therm. is a 180* the 20* diff or so because of the sender location seemed right to me.

The last few days have been warmer than before. 70-80 degrees and it still wouldnt get above 140* on the gauge. Maybe the therm is stuck open. Thats a good possibility.

I am leaving town for 3 days so when I get back I will have to start diagnosing this. I may put the 160* stat back in and see if that changes anything. But seeing as that the Meziere pump uses a standard chev SB thermostat I may have just got a crappy one from Schmucks when I relpaced the 160 with the 180.
