Question about 2002 Volkswagen Jetta TDI
We replaced the coolant, then the heater core shot! we bypassed the heater core (to drive it), and put more water in it. ran fine as long as i didnt go over 55 on freeway. THEN we put VW coolant in it and now its overheating. cant get 1 block and its at 230! we pull over & engine is cool to touch, but idiot lite reads 230. we've been burping the system but it takes forever! My Bro is a great mechanic but this is systems & im thinkn its over his head. Fans are on (hardwired so theyre on all the time cause the O-heating). Its as if there is no flow of coolant mix, although we did unhook hoses & theyre full. Ive replaced coolant flange. - was reading a post bout the water pump propellor might be broke....could the water pump be bad? Is it casue we bypassed the H-core? does it just need a big-*** burp? should i just replace the themostat AND water pump? i need my car for work, HELP! :)
Had similar problem on my 2000 cabrio---hit the dashboard lightly above the temp gauge and it dropped to normal reading---the temp gauge spring was oversprung from the previous overheat problem I had---as long as the engine is cool --then so are you
