Author Topic: s trim 306 running hot after traffic or hard driving street_illegal_stang ¯ Member # 1554 posted                              question is the topic. I have a 91 lx with a o-ringed stock block ,twisted wedged heads with head studs,saleen intake stage 3 ported matched to the heads,trick flow stage 2 cam,msd btm,s trim, Mac 1.3/4" long tubes w/ 3" pro camber pipe and 3" mac catback,tko,60 lbs injectors with supporting parts,7 qt canton oil pan,and dynotuned by grc with diablosport chip. Now for cooling I have a 3 row alum fluidyne radiator,180 thermostate,i think stock w/pump,and A electric fan with shroud on a thermostat. Do you think I should just run a toggle switch to the fan? What are the chances of a thermostate getting stuck open? The car warms up to 180 after 10mins But gets hot to like 205-211 after 25mins ... I took it to the drag strip the other night and run once then did a hot lap,and after that run she shot up to 210 again. THE OiL Is Clean! Im gonna pressure test the cooling system when i get a chance. btw it stays below 180 cruisin on the freeway above 65mph. I run 91 octane with 108 turbo and Keep the timing low. what do you think? I'll be out till friday fyi.

I run the same set up as you but a 331. I have a 3core rad but use a stock clutch fan. I can not get my car to heat up. i had to use cardboard and drive 10 miles to heat it up enough for smog. It doesn't sound like you are pulling enough air.

Is the fan rotation correct?

This sux cause its kind of a expensive setup. Posts: 1276 | From: Long Beach C.A | Registered: Jul 2002  |  :
