Will the catalytic converter cause the engine to run hot? My CC has been rattling inside for a couple of years now and here lately I have been having trouble with the engine running warmer than normal, apprx 230*, standing still or cruising down the highway. I thought that I heard somewhere that they could get plugged up and cause the engine to run hot, anybody got any ideas about this? thanks, Jim ------------------ '84Z28/'92 305TPI '92 complete rear suspension/PBR disc/Posi/3:42 Light weight 34.5mm stabilizer bar in front ($10 from wrecking yard)/ "wonder Bar" ($5 from wrecking yard) 23mm sta. bar in rear Rear RS Springs (slightly softer than my Z28) comp cam, flowmaster TB coolantbypass/shutoff valve to heater core powersteering cooler lines (liberated from another wrecked car of course) MAT relocated Ram-Air(home-made) gutted air-box IROC ground effects/wheels GY245/50's 700R4 superior shift kit/ corvette servo(excellent shift kit btw) home-made strut tower brace (cost $6) Rebuilt engine and transplanted it myself.

this could possibly cause the car to heat up, although 230 isn't really a danger zone. But if this is a major change from what it's been running at, then I would check a couple of things. 1.make sure the cooling fan is coming on, and at the proper temperature(around 220 degrees)-ignore if you don't have an electric fan 2. check to make sure your thermostat is not stuck shut 3. make sure that you have changed your coolant within 50,000 miles 4. check to see if your water pump is leaking or siezing |
Yeah, if your cat is plugged it could be causing increased back-pressure which would cause your engine to hold more heat. ------------------ iso 91/92 camaro. 96Z M6 subframe connectors, boxed trailing arms, tubular panhard rod, BMR stb, SS rims, 6 point cage, other misc. debris |
Dont know about anyone else, but my car gets cooler going down the highway. Check to see if your front air dam is intact and not damaged. I believe our cars get 80% of cooling air, if you will, from under the car. Hopefully that helps. Also check other things already stated. |
If your cat was clogged you'd hear it. It would most likely make a whistle sound. That's the exhaust escaping from the cat and the y pipe connection. Check to see if your air dam is still there, and consider getting a 160 or 180 thermostat. With a 160, install a switch to kick on the fan whenever you want. But with the highway temps not going down, it sounds to me the airdam is your most likely suspect. 230 is high, mine runs best in the 180 range. 220 is the most I'll ever let mine get. ------------------ Member of the Jersey F-body Association (JFA) 1989 Camaro Convertible RS Gunmetal gray w/black top 305tbi, auto, 3.73 posi SLP exhaust, 16x8 black GTA Crosslace Rims Check out Phil's Rice Boy Page |
