[TR] heater valve on block tr-3

[Bill Brewer]

     I have a Marandyne heater in my TR3. I think that I was the first person to post it to the list originally.

     I made a new heater valve for the top of the head from fittings from the local TruValue hardware store. I used a ball valve with a lever handle and had to make a fitting to match the hose to the firewall fitting. Has worked great for about 10 years.

     The major issue with my heater was the return pipe that goes from near the firewall to the water pump on the driver’s side. Mine had rusted solid since I had checked it last. I replaced it with a stainless steel one from either TRF or Moss. 

     My Marandyne heater works great still. My TR3 heater was always pathetic.

first wanna thank the list and specifically Randall for help with starter solenoid ?.  Tested and found solenoid was bad so all is well.

 

Just had a question for the list.  I'm just not getting as much heat through the Marydane (sp) replacement heater in tr-3.  Temp guage shows 185 degrees but temp through heater is warmish and I can grab with my hands the heater hoses going into the heater.  Checked flow and everything out and I'm pretty sure its the heater valve on the block.  It's the faucet type with the green round handle.  I'm thinking the inside broke loose and its closed.

 

several years ago I bought a radiator valve of a similar type and it leaked as soon as I filled the radiator.  My heater valve came from the same vendor and I'm guessing they both might not be made well.

 

Just wondered if anyone else on the list has had these valves fail.  I'm planning on replacing with a later valve.

 

Thanks
