Hi, It's me again with another question for the jag experts. All the tech articles I've read seem to talk about the engine & trani in the series III jags run on the hot side. Can I get input from you guys on these 3 questions:

Should I install a 160 degree thermestat vs. the 180?
Do you recommend installing an aftermarket trani cooling system?
What about aftermarket oil cooling system?

Also are the aftermarket cooling systems relatively easy to install?

Thanks!

 

where can i buy a tappet hold down kit? How much do you figure it will cost me? Is it something easy to install or do you recommend install by a mechanic? thanks for your help!
