[TR] Overheating Project

Curious why you feel the need to replace the timing chain and sprockets?  You're just close enough into the engine so you might as well?  Which makes sense.  When installing the front plate back on, I used Permatex Ultra Black along with the new gasket.  No leaks.

When I rebuilt my engine I did replace the timing chain and gears.  I pretty much replaced and/or rebuilt everything.  As for the timing gear that bolts to the cam, mine was also a general one so no timing mark on it. I was able to align the old gear and new gear and then used a spring loaded punch to transfer the timing mark to the new replacement gear.  https://express.google.com/product/6336481475320676757_17424741397128436922_8613692?utm_source=google_shopping&utm_medium=tu_cu&utm_campaign=8613692&pdata=CgUzNS45OQ&utm_content=eid-lsjeuxoeqt,eid-dqdncagwvd

Also, be sure to rotate your engine so #1 is at TDC before messing with the timing gears.  There is pretty detailed instructions in the Haynes manual and others.  Probably a YouTube video or two, and Moss must have a video too.

I converted to an electric fan and have been very happy with it.  I was even in a parade on July 4th, and most of the route was slightly downhill so I was just idling as I very slowly coasted in neutral down the hill for about 30-40 minutes.  My water temp fluctuated between 190 and 200 degrees.  It was very fun as some of the kids would yell to me to rev it up, which of course I did.  Got some cheers for that.  :-)  I also added an overflow bottle to my cooling system.  I really like this one as it's stainless steel, and with the hose up the side I can see the fluid level.  https://www.summitracing.com/parts/mrg-9135/overview/

Good luck,

Fellow Listers,

My 1962 TR3B has had a problem with overheating.  I replaced the thermostat (although not the sleeved one) to no avail.She used to overheat at idle and now even with motion.  Previously I have installed an electric fan, the radiator air shroud and bypassed the heater so no fluid goes there (as she is not driven in bad weather anyway).

I would fill up the radiator, and go for a drive...overheat and fluid gone upon return.

So I puschased a new aluminum Wizzard radiator, new hoses, new water pump and pulley, 8 blade yellow fan from TRF.  As long I was in there figured I should replace the timing chain and sprokets.  Finally got past teh house projects to work on her.

Goal on 4th of july was to get the apron off....5 hours later success...it was not too hard, just tedious.  the lateral fender bolts prooved most difficult, but PB Blaster and heat got them going...thank goodness. (anyone wanting advice and how to on that let me know).

Took the radiator off today.  No fluid in thermostat housing but drained a lot from bottom of radiator once bottom hose removed.

Question #1: I see the petcock on the back of the block.  Should I remove that and flush a garden hose in there to see if it clears or go with radiator replacement (once all the other stuff is done)?  The hoses are off and the heater cock has a hose going to where the heater pipe hose would be...where will the water come out of?

Question #2: Need to take the fan off next...any tips/advice on this, especially considering I have to put the plastic yellow one on and the TRF stuff did not come with instructions.

BIG FEAR: The timing chain scares me...never done that before and the new sprockets from TRF do not have markings...more on that after fan removal and water pump removal.

THis list is the best and thanks for any help and advice.
