Pulley Diameters

Not a hijack. Please continue as I think this may help more members than just us. I've read a ton of threads on heating/cooling & I don't recall seeing much info on pulley diameters, etc.

I can live with 210* if that as hot as it gets, but NOT the case. I agree with you & don't like it at all...




Let us know what your radiator guy says. I'm determined to fix the problem this year once & for all....I HOPE :) (Fingers Crossed)

C, I have to agree with a few of these post and since I have seen your cooling system and you even swapped out the fan clutch AND have a shroud I have to lean towards Robs radiator thoughts.
I don't remember specifically what electric fans you have, but it sure is possible they are blocking too much air when not in use.

I'd pull those and see if the car will idle and stay at pretty much what your thermostat temp rating is.
If it wont keep the temp down at idle with the electrics out of the way you know right then there's going to be a problem when out somewhere with the car.

If it can idle without getting too warm then take it out for couple of miles and see if it runs 200-210 or so without going higher.
If it does that ok turn your air on and see if it stays around the 210 or so area.

I am taking into account an approximate 80 degrees out when estimating this.

If it keeps climbing you need a more efficient radiator.

Oh, and 1:1 or close to it on crank and water pump pulleys is an acceptable norm so please excuse me for being skeptical on that new pulley helping anything.
