cletus Posted March 26, 2018 Share Posted March 26, 2018 mine was not meant to have a 20psi cap on it. not sure what it was meant to have from factory- probably 9 or something like that? 7 was just because there was one in stock in a box under the house my concern would be using a higher pressure cap, on components that are designed for a lower max pressure. it may well be fine and I might be talking out of my bottom, wouldn't be the first time Quote Link to comment Share on other sites More sharing options...

tortron Posted March 26, 2018 Share Posted March 26, 2018 I figure a full metal rad and heater core is probably up to it though Thinking about it it's always going to operate at its normal pressure anyways, unless it overheats. Which I think is why dingo cars have such high pressures so they don't boil in the desert right So Idk probably it doesn't matter anyways Bang one on and see what happens probably Quote Link to comment Share on other sites More sharing options...

ajg193 Posted March 26, 2018 Share Posted March 26, 2018 You could run that waterless coolant if you want. Super high boiling point so won't pressurize your system (according to Jay Leno). But yeah, if your overflow bottle is getting filled then you are getting to the rated pressure of the cap. / Water expands when hot Quote Link to comment Share on other sites More sharing options...
tortron Posted March 26, 2018 Share Posted March 26, 2018 Yes I'm aware, Main concerns/thoughts are around efficiency differences in the system. Higher pressure tends to give better flow, less hot spots. Possibly less cavitation at the pump. Also, if the gauge red is set for high pressure and therefore higher temps then I may actually boil it at 3/4 for example. Quote Link to comment Share on other sites More sharing options...
tortron Posted March 27, 2018 Share Posted March 27, 2018 On a related note Laser says 95C at top tank and 63 on bottom hose when gauge is at 3/4. Cooler than I expected Quote Link to comment Share on other sites More sharing options...

Or under the floor? I can't access my rx30 very well at the moment but am trying to decide if I should pull the fuel tank from the rx60 im wrecking.

tortron Posted March 31, 2018 Share Posted March 31, 2018 Oil filter sandwich plates. Are they much of a muchness or should I get name brand? Want one with a thermostat in it Quote Link to comment Share on other sites More sharing options...
Transom Posted April 2, 2018 Share Posted April 2, 2018 Silly clutch questions Release bearing should just against pressure plate at rest (clutch out ) ? how far should the pushrods be into the slave cylinder ? Push cylinder Mazda rx/mx/5/6 bits have a few lengths of pushrods here or can it be adjusted by shimming the pivot ball? Also ..... should the release bearing be almost at the end of the gearbox input snout it slides on (will slide partly off when clutch is pushed ...) ? Thanks never done a Frankenclutch before ...

MightyJoe Posted April 2, 2018 Share Posted April 2, 2018 Has anyone tested the pressure of w cooling system? Just cos it says 20psi on the cap doesn't mean the 27 year old rad cap will provide 20 psi of closure. My truck used to spill it's coolant daily. Until I replaced the rad cap with a 17psi instead of 12. That was after first trying a new 12psi rated rad cap and doing a head gasket comp test. Leakdown etc etc. Quote Link to comment Share on other sites More sharing options...
tortron Posted April 2, 2018 Share Posted April 2, 2018 My old one had a leaky seal so no it was holding 13psi. I am using a new 13psi one now. I did try the 20psi one a little while ago and it didn't explode Quote Link to comment Share on other sites More sharing options...
peteretep Posted April 2, 2018 Share Posted April 2, 2018 On my escort, according to the manual when you set up the clutch cable, there should be about 7-8mm travel in the cable between release bearing and fingers. This would equate to 3-4mm actual distance between release bearing and clutch fingers due to clutch arm pivot. That’s pretty old tech though, so could be different in more modern stuff 1 Quote Link to comment Share on other sites More sharing options...
Transom Posted April 2, 2018 Share Posted April 2, 2018 Cheers ... managed to find some googles on aftermarket clutches and release arm angles and free play at pressure plate as well will carefully throw it together with some measuring give it a bleed and see what I can see thru the starter hole Quote Link to comment Share on other sites More sharing options...
AllTorque Posted April 2, 2018 Share Posted April 2, 2018 You don’t want the release bearing touching the pressure plate when disengage. It will wear the bearing out fast if it is always spinning. Quote Link to comment Share on other sites More sharing options...
