Thread: Hot Running Engine

Tweet

I have a 305, an autozone reman with about 15k on it.
It was in an 84 camaro (with all the 84 emmissions crap) and it wold run hot - as in boil over once parked after 30-409 minutes of driving (even hiway cruising).

I had the rad checked for HC (leaking head gasket) and no problems found.

Put the engine into a Jeep - taking out a 78 or so 305. replaced the 84 parts with the 78 305 parts: carb, dist, water pump, new temp sensor for guage, new 180 thermostat. Kept the 'jeep' fan, rad, shroud, exh manifolds. I didn't check the pump - it don't leak and the pulley turns. no idea if it pumps though.

When i got the jeep the 305 had a broken rod. The PO said it ran fine until then (no overheating) so I assume then the cooling system is OK. (rad, pump, fan/shroud combo)

I set the timing to max vac at idle..pinged when at p temp up a hill so ihave backed it off. I will be re0checking thte TV cable as well and after it cools go for another ride.

Since the motor ran hot in teh last car and this one, i assume the motor is the issue...any ideas on what is the cause or what to try to cure it? A bigger rad is not my first choice cost wise, but it has just a 2 core in it now (the camaro had AC (broken) and only had a 2 core in it)

Should i just change the water pump for the heck of it? i have the old camaro pump...i can check it - i doubt BOTH pumps would not pump. I left the cap off to bleed...never did see the flow i was expecting BUT i may not have let it get hot enough fot the thermostat to open..will check for flow at lunch.

Any thoughts?
