His radiator is a RH setup from the early/mid 90's. It is two 3 core radiators setup as a double pass unit. The water flows through the front 3 rows then through the back 3 rows. It uses a Corvette electric fan and a VW rabbit thermostat switch for the fan.

IF.. the pics posted here where of his car...

Howard when I looked at the pictures of your car on Ebay. The cooling system was a early Renegade. It is two radiator cores one in front and one in the rear and a double pass system with the water going to the front core first and then to the rear. If you look you can see that the common tank is on the left. I had one of these in my car at first and it cooled great. This is really a good radiator and should cool your car fine.

With the temp. sender in the head its going to read hotter than if it was mounted on the intake by the thermostat.

What kind of Heads and headers are on your car? I can see that the headers are for spread port head and it looks like a adapter is used for a standard head. This is really a good thing you don't see these everyday.

Lets see some more pictures of the radiator and how the thing is plumbed up.

I'm just happy you are contributing. I'm seriously thinking about a V8 conversion area on the BBS. I have customer cars in the shop right now that have NO idea where to turn too for minor tweaks/issues that may arise during their ownership of converted cars. The common denominator they all have: web access/hate email groups/own V8 914's. humm...

Brad,

I think that is a good idea. From what I see, most of the V8 guys tend to lurk more than contribute and understand why. I've gotten over it and don't mind mixing things up.

A separate V8 section would make it easier for the newbie to find information specific to his car.

John, Bob, Asshole...

Obviously, not sure what I've got here, but do have a file folder full of receipts. Will go thru them to look for some key words on motor.

Back to sender. Should I just get another sender and put in intake manifold? Current one is useless, as it goes right to 240 and sits there. Fan, no fan, warm day, cool night, at speed, at idle, in traffic, 10 minutes after shutdown, it's 240.

Anyway, will remove cover and try to get some better rad pictures. As far as heads, engine specs and such, send in the experts. Headers are beautiful jet coated thingies that sound great, but don't know much more as of now. Someone local know this shit?

Howard I didn't see your first pictures that you linked to on your post. That radiator is just as Brad and I said. That thing will cool your car.

After looking at the pictures It sure looks like a well built car all an fittings on the water pump and those headers look great. If the rest of the car is like the few pictures on you web page you got a hell of a deal.

Howard,

I'm with Bob, you got a deal! I'd hate to admit what I have in my car and still need to paint.

Yes, I would just buy another water gage and install on intake. The pictures I included that showed top of my motor are the most common places to mount sender. You should have at least one mounting position on either left or right side of thermostat housing. Look for a pipe plug about 1/2" in dia.. Note: buy a matched set (sender and gage) as you don't know which part of your system is bad.

I prefer the mechanical gage. It takes a little longer to snake the larger tube from front to back as opposed to a thin wire, but the readings are accurate and instantanious. I recommend the Autometer 2-5/8" mechanical #105-4433 from Jegs (1-800-345-4545) or similar for about $75. It comes with 12' of tubing necessary for routing in a 914 and you can easily mount under dash, in center of car for easy viewing.

Look forward to reading about your results.

John

Latest comment from 'knowledgeable' Chev mechanic.

Later V8's have the temp sensor in the head, right between the exhaust ports. Hottest spot in engine, and 240 is 'nominal'.

Gauges on stock cars don't list degrees, just C to H. He said to get one of those and don't panic. Did show me aftermarket replacement that goes up to 270. Is this all BS???

My current V8 has two h20 temp gauges, one is a regular h20 temp gauge reads up to @220??? I will have to look, the other is an oil temp gauge that reads up to @310 ?? Both are mountd on the dash one in the ashtray hole and the other where a radio used to lurk.

Howard he is right. Thats what I said in one of my post. I went thru this with a freind. His car would read about 30/40 degrees hotter than the gauge in the intake.

Thanks, needed moral support, guys. Don't know if true, but for all you really old pharts...

Ford came out with the V8-60 in the early thirties. The '60' was the 60mph brag for top speed, something unheard of in an economy car.

The story goes.. A guy buys one that won't go past 55. Takes it back to dealer several times without satisfaction. Deal ends up on Henry's desk. Memo from him to dealer: Adjust speedometer, dummy. (IMG:style_emoticons/default/smilie_pokal.gif)

I don't need no estinkin' gauges!

Howard,

I was not actually trying to be an asshole at that point. I could'nt tell who was posting pics of whose car. I knew you owned one...

Holy shit, Brad. Don't go sensitive on me. Ragging you is the only way I can pay you back for the great advice. (IMG:style_emoticons/default/wub.gif)
